In this blog, you’ll learn about spider mites and the types of damage they cause, how to spot an infestation, and natural spider mite prevention with chemical-free solutions to protect your plants.

Plant infections are common, widespread, and can be a real challenge to treat – especially fungal infections, which are responsible for 85% of plant diseases.  Fungal diseases can wreak havoc on crops, causing damage ranging from deformation and defoliation to twig, limb, and plant death. From leaf spot to root rot, infections cause a 10-20% loss in crops each year – equivalent to $100-$200 billion in the U.S. alone. The keys to preventing fungal pests are proactive treatment and prevention.  To effectively treat a fungus, it is crucial to first recognize the signs and symptoms of an infestation. But with more than 19,000 kinds of fungi causing disease in crops worldwide, identifying which type is causing damage can be overwhelming.  In this blog, you’ll learn about some common fungal infections found in both plants and crops, how abiotic and biotic factors play a role in fungal infections, how to diagnose and manage fungal disease, and tips for preventing infections. Common Fungal Infections The sheer number of fungal pathogens makes it near impossible for the average grower to isolate what type of fungi is damaging or destroying a plant, but there are common fungus infections that you are most likely to encounter.  Following are some of the most common fungal infections and visible signs and symptoms they may be infecting your foliage:  Blight affects fruits, vegetables, and flowers, as well as trees and shrubs. It impacts the leaves, stems, fruit, and tubers, and limits yield. It can live within the soil and has the potential to cause a total crop loss. There are multiple varieties of blight. “Early blight” is caused by Alternaria tomatophila and Alternaria solani and appears in moderate to warm temperatures – 50 to 86 degrees. It thrives in humid conditions, including wet weather and heavy dew. Early blight symptoms first appear as brown spots on leaves and stems at the base of affected plants. These roughly circular spots may have a yellow halo, and as they enlarge, concentric rings appear, giving the areas a target-like appearance. Multiple spots on a single leaf will eventually combine, leading to extensive destruction of leaf tissue. Early blight can lead to total defoliation of lower leaves and kill an infected plant.Despite its name, “late blight” may occur at the same time as early blight but may not be visible until later in the season. Leaves of plants infected with late blight exhibit pale-green or olive-green areas that quickly enlarge, becoming brown-black, water-soaked, and oily-looking. Stems may also exhibit dark-brown to black areas.  This fungus can impact multiple plants, but tomatoes and potatoes are especially susceptible, and it is responsible for $6.7B in potato crop losses annually. (Late blight was responsible for the 1840’s Irish Potato Famine that killed 1 million people.) Potato tubers may develop sunken areas with a reddish-brown skin discoloration. Tomato fruits develop large, often sunken, golden- to chocolate-brown, firm spots with distinct rings. Affected leaf, stem, fruit or tuber tissue often eventually develops a white-gray, fuzzy look as the late blight organism begins to reproduce. Cool, wet weather conditions can lead to plant death from late blight in just seven to 10 days.  Anthracnose is another type of blight. It involves a group of related fungal diseases that can produce dark lesions that may be black, brown, or tan, depending on the host plant affected. Sometimes called bud, leaf, shoot, or twig blight, this fungus causes the most damage when prolonged spring rains take place soon after new growth develops.This pest may appear as irregular, dead areas on leaf margins, between and across and/or along veins, often moving onto the shoots and small twigs; sometimes whole leaves are engulfed. Large areas of infected leaves turn brown and fully infected leaves will drop. Anthracnose can cause gnarls or growth distortion, but doesn’t threaten the host plant unless defoliation, dieback, or cankering happen yearly.  Black spot, caused by the fungus Diplocarpen rosae, targets roses. Infected areas range from brown to black, are roughly circular shaped, and may be up to half-inch in diameter, often with feathery margins. Black spot initially appears during periods of wet weather, starting on lower leaves before spreading to the entire plant. Severe black spot infections cause yellowing and leaf defoliation. It is not considered fatal but can weaken infected rose bushes, making them more susceptible to other pests. Leaf spot appears as a dead area on a leaf surrounded by healthy tissue. These spots are usually seen on the lower, inner branches, where humidity is high and leaves are shaded, and may occur on the upper, lower, or both surfaces of the leaf. Spots may range in color from yellow to orange to red, tan, brown, or black and appear in every size and shape, although they may start as random spots that appear after the pathogen lands there through wind or water splashes. This type of fungus weakens trees and shrubs by interrupting photosynthesis. It may affect only a small portion of the host plant but, if it causes moderate to severe damage during consecutive seasons, it may result in a weakened host that is more susceptible to other pests and diseases. Powdery mildew is one of the most easily diagnosable fungal infections, identified by its resemblance to baby powder being shaken onto a leaf. Caused by multiple genus of fungi and most often seen on the surface and sometimes the stems of leaves, powdery mildew does not require moisture to infect a host and can survive dry seasons as a result, unlike most other fungi. The extent of damage from powdery mildew ranges from purely cosmetic to instances of leaf drop and distortion, and the death of young shoots. Downy mildew can be difficult to diagnose because there are many species of the disease, sometimes only targeting one type of plant, and each producing lesions of different sizes and colors. Caused by the fungus Pseudoperonospora cubensis, downy mildew affects a number of edible plants, including cauliflower, broccoli, lettuce, cucumbers, grapes, as well as ornamental varieties ranging from trees and shrubs to annual and perennial flowers. Downy mildew symptoms begin as small, water-soaked spots, appearing first as slightly yellow-green and progressing to a bright yellow on the upper leaf surface. Lesions become angular, brown and distorted as they progress, and plants may defoliate. More harmful than powdery mildew, untreated downy mildew can lead to damaged fruit and crop losses. Oak leaf blister is caused by infections of the fungus Taphrina caerulescens. Leaf blisters usually appear several weeks after an infection has occurred, often as leaf buds swell and open during wet, spring days. These blisters may appear as light green bulges on the top of the leaf, with the underside appearing to have a sunken, or depressed, area. Given time, the blisters may become dry, brown spots. Affected leaves may bend or curl but the fungus does not endanger the host plant. Rust is a common fungal disease in the order Uredinales that is often identified by the red, orange, brown and yellow spots it produces on leaves. Raised pustules of powdery spores may form on the underside of the leaf surface, but may also appear on any green part of the plant, including the stem and the flower calyx. Severely infected leaves may turn brown or yellow, and may fall off. Plants infected with rust disease may experience stunted growth or easily wilt. Wilt is caused by fungus Fusarium and Verticillium, two different species that cause similar symptoms in broad leaf plants. Individual branches or even single leaves may be affected at first, with infected foliage displaying a wilted appearance before developing a yellow color, often in V-shaped sectors between the major veins. Leaves eventually die and fall. Wilt may cause discoloration or brown streaking in vascular tissues. Diseased plants may die soon after first symptoms or they may sprout at the base after the top dies. Root rot may result from a number of soil-borne fungi, including Pythium, Phytophthora, Rhizoctonia solani, and Fusarium, which are the most common varieties. Because they have wide host ranges, these four fungi types can cause root rots on a wide variety of plants. Infected plants may exhibit wilt, even when the soil is moist, and have leaves with a yellow or red color consistent with a nutritional deficiency. Roots often have a bad odor and may be soft and brown. Root rot can lead to plant death. Several of the common fungal diseases above affect both edible and ornamental plants, trees and shrubs, but there are a few crop-specific fungal diseases that are also frequent pests for farmers. Septoria leaf spot is a fungal infection that targets tomatoes and is caused by the fungus Septoria lycopersici. Symptoms typically begin as plant canopies start to close and usually first appear at the base of affected plants, where small, whitish spots with a dark border spots appear on leaves and stems. Eventually multiple spots on a single leaf will merge, leading to extensive destruction of leaf tissue. Septoria leaf spot can lead to total defoliation of lower leaves and the death of an infected plant. Clubroot commonly occurs in brassicas roots, affecting crops like cabbage, cauliflower, turnips, and brussels sprouts. From the Plasmodiophora brassicae family, clubroot causes roots to swell and become distorted, sometimes appearing spindle shaped, and hinders the roots’ ability to absorb water and nutrients. Above-ground foliage may be stunted and appear purplish, with wilting leaves. The disease may kill young plants; older plants may fail to produce yield. Damping off impacts seedlings. Commonly caused by the fungus Pythium, it may also be the result of pathogens from the Rhizoctonia, Fusarium, and Phytophthora species. Seeds infected before germination may fail to grow, and those seedlings that do emerge may become soft and mushy, turn brown, shrivel, and decay. Seedlings attacked after they emerge will show decayed and weakened stem tissue near the soil line, usually causing plants to topple and die. If only the roots are decayed, seedlings may continue to grow slowly or may eventually die. Black leg disease impacts canola crops, including cabbage, cauliflower, turnips, and occasionally mustard, and is caused by two species of the Leptosphaeria fungus. Signs of the infection include circular, grey spots on leaves, with black pepper-like specks appearing in the center of the spots. When symptoms are severe, numerous leaf spots develop in the lower canopy, resulting in lower leaf yellowing and death. The spots become tan as they age. With time, lesions or cankers develop on the stems, and may extend into the stem, resulting in premature ripening and incomplete pod fill.  Fusarium is a common fungal disease in agriculture. Fusarium oxysporum is a complex fungus that has many host-specific strains often infecting tomatoes, cucumber, watermelon, eggplant, and pepper crops. Symptoms may begin on lower leaves before moving up to impact the entire plants. Temporary wilting – during the heat of the day and with overnight recovery – eventually becomes permanent and yellowing follows. The discoloration may only develop on one side of a shoot or branch. Brown leaf tips may occur, and will give way to full leaf death and the loss of the host plant.  Scleratina blight, which may also be called white mold, timber rot, drop, or head rot, is caused by Scleratina minor, and impacts leafy greens and cole crops, legumes, and root vegetables. The first symptoms of infection appear as a fluffy or cottony, white moldy growth around diseased areas of lower stems. On affected stems, tan to pale white lesions will develop and appear sunken and elongated. Soon entire limbs wilt and turn yellow. Affected branches die and turn dark brown in color and eventually whole plants die. The fungus rots stem tissue, leading to stem shredding, which means pods are unable to develop. The above is by no means a comprehensive list of all fungal infections but it comprises many of the diseases growers regularly face. How Do Fungal Infections Develop and Spread? Interestingly, a plant disease is considered a malfunction in the plant in response to continuous irritation by a causal agent.  Development. The causal agents of plant disease are biotic (living) and are called pathogens. However, not every pathogen can cause an infection. A disease can only develop with three criteria in place simultaneously: A pathogen comes in contact with a susceptible host plant during favorable environmental conditions that enable disease development. Fungi have several different lifecycle patterns based on the genus. Regardless of the species, growth and feeding take place during the vegetative stage, which is when microscopic threads called hyphae develop and absorb nutrients from the environment. Hyphae growth can distribute the pathogens that spread disease. Hyphae may form a visible network of thread-like structures called mycelium, which release spores to spread the fungus to other host plants.  For a disease to spread, a pathogen requires inoculum, which is any part of the pathogen that can cause infection, including spores, particles, cells, or nematodes. In the case of fungal diseases, fungal spores or mycelium make up the inoculum. These inoculum can be found in soil, seeds, weeds, and other crops or crop residue.  The fungal disease cycle follows this pattern: The pathogen is spread. The inoculum penetrates the host plant. The infection develops within the host plant. Secondary cycles begin, producing new pathogens. The inoculum survives between growing seasons. Dispersal. Fungal diseases may reside in seed, soil, crop residue, other crops, and weeds, and are easily dispersed by any number of factors. Weather elements (wind and rain), contaminated items like gardening equipment, gloves, or clothing, or a vector—a living organism that transports a diseased spore between plants, like an insect or a pollinator.  Many fungi survive the winter in infected plant parts, including bulbs, roots, stems, and bud scales, emerging during the growing season and spreading as mentioned above when the conditions permit. Some, like powdery mildew, may spread for hundreds of miles carried by a gust of wind, making these pests challenging to contain and manage. Diagnosing and Confirming the Disease Plant diseases may be biotic or abiotic, or both. We covered several biotic, or living, diseases above. Abiotic plant disorders are not associated with a living organism like a fungus, but are attributed to physical, environmental, or chemical factors. Physical. Types of physical factors that may impact plant growth include poor planting methods – not providing for deep enough root development, for example – along with improper pruning and soil management, and take their toll on gardens and landscapes. Environmental. Climate conditions play a significant role in plant disease. Soil that is consistently too dry or too wet weakens a plant’s immunity, as do temperature extremes and too much or too little shade. Drought stress and cold injury lead to conditions like leaf scorch, leaf drop, and branch dieback, all of which lead to weakened immunity against fungal infections. Chemical. Abiotic plant disorders result from chemicals like fertilizers and pesticides used to fight plant disease, but they can also result from factors unrelated to agriculture, like air pollution, spilled motor oil or drain cleaners, and ice-melt mixtures that make their way into soil and impact vegetation. These chemicals cause phototoxicity in impacted plants, which can result in leaf cupping, distortion, wilting, browning, stunted growth and plant death. While these abiotic physical, environmental, and chemical factors may result in plant disease in and of themselves, they also create ideal conditions for biotic fungal infections to occur should a pathogen be introduced. Given the information above, growers may be able to diagnose some fungal infections by doing a bit of research without expert input. Following these steps can help you identify the cause of a plant disease and ultimately take steps to manage an infection:  Identify the host plant and how a healthy specimen should look. Multiple species of the host will have different appearances and it is key to ensure the correct variety. Examine the plant for symptoms and signs. Carefully inspect each aspect of the diseased plant, from the leaves to the stem and roots, taking note of color and texture variations that appear unusual. Research common problems for the plant. Understanding frequently seen issues may help dismiss disease concerns. Consider which causal factors might be biotic and abiotic. Plants that were placed in unfavorable growing locations may be failing due to location versus infection. If you’re unsure whether your plant is infected by a fungal disease, reference materials also serve as excellent resources. Experts at local garden nurseries or college extension offices, which are staffed by people with knowledge of plants native to that location, are also able to help diagnose plant diseases. Many states also have a plant diagnostic lab that can assist in identifying infections. Treating, Managing, and Preventing Fungal DiseasesIntegrated pest management, known as IPM, is a science-based approach that employs multiple methods to manage plant health by managing the ecosystem. Cultural disease management strategies are based on good sanitation and husbandry. Controlling plant diseases with cultural practices is based on improving the growing conditions for maximum plant health while preventing the environment that enables pathogen growth.  Some examples of IPM practices include yearly crop rotation, which can disrupt year-to-year pest cycles; interplantings, or alternating different plants within rows or patches to minimize infestation; weed management to diminish habitats for pests develop; watering in the morning to enable plants to dry thoroughly before cooler, humid evenings foster fungal growth; and pruning to promote air circulation around plants to discourage infection.   IPM also involves the premise of biologic control: using nature against itself. For instance, to control insect populations, introduce their natural enemies. Biologic practices promote long-term sustainability by preserving natural predator-prey relationships and reducing the risk of pesticide resistance.  Chemical solutions are considered part of IPM, but only those with natural ingredients should be introduced. Unfortunately, growers relied on toxic chemicals to manage plant diseases for decades with disastrous results. The damage from prolonged use of pesticides and fungicides is well documented on people and our planet. Pesticide use is responsible for causing everything from physical issues including chronic illnesses and human death to environmental impacts including polluted waterways and soil and endangering beneficial insects and wildlife. What’s more, after years of exposure, many diseases have developed an immunity to pesticides, rendering their use ineffective against pests like fungal infections.  As part of a safe IPM practice, growers have a safe, organic option when it comes to treating, managing, and preventing fungal infections: GrowSafe. An all-natural formulation made of a proprietary blend of food-grade ingredients, GrowSafe kills fungal disease on contact and provides a physical coating that acts as a defensive barrier against figure fungal attacks, promoting higher yields and healthy, disease-free plant growth.   Better and safer than chemical-based pesticides and fungacides, as well as neem and mineral-based oils, GrowSafe’s all-natural ingredients won’t harm the environment if it gets into the soil. The product is safe for people, pets, pollinators, and beneficial insects that come into contact with treated plants, and treatment will not change the smell or taste of herbs and botanicals, fruits, or vegetables. Regular monitoring and a proactive approach are key to managing fungal infections. The conditions will always provide an environment in which fungi can attack foliage, but taking steps to recognize the early signs and symptoms of a fungal infection, and utilizing a combination of IPM cultural, biological, and chemical controls like GrowSafe as a preventative and treatment tool, creates a strong pest management strategy against this destructive disease.   ***********************   Blog Outline: Identifying and Treating Common Fungal Infections ___________________________________________________________ Introduction Plant infections are common, widespread, and can be challenging to treat Fungal infections aren’t the same as viral or bacterial types and require different disease management Know what to look for and how to treat various fungal infections  In this blog, you’ll learn about common fungal infections found in both plants and crops, how abiotic and biotic factors play a role in fungal infections, how to diagnose and manage fungal disease, and tips for preventing infections.  Source: https://www.canr.msu.edu/news/signs_and_symptoms_of_plant_disease_is_it_fungal_viral_or_bacterial  Section 1: Fungal infections  Common types of fungal infections, with signs and symptoms of each Blackspot Leafspot Powdery mildew Downy mildew Blight Plant versus crop fungal infections: Differences and similarities Sources: https://ipm.ucanr.edu/home-and-landscape/anthracnose/pest-notes/#gsc.tab=0; https://www.canr.msu.edu/news/signs_and_symptoms_of_plant_disease_is_it_fungal_viral_or_bacterial Corn/Soybean info: https://crops.extension.iastate.edu/cropnews/2010/06/early-season-diseases-showing-corn-and-soybean-fields Wheat info: https://agcrops.osu.edu/newsletter/corn-newsletter/2017-09/facts-about-early-season-wheat-diseases Orchard info: https://extension.uga.edu/publications/detail.html?number=B1336&title=diagnostic-guide-to-common-home-orchard-diseases Section 2: How do fungal infections develop and spread?

For decades, growers have depended on pesticides as a defense against invasive pests and diseases ravaging their crops – but research has proven plenty of dangers associated with these chemicals.  Fortunately, there are safer alternative ways to protect crops, ones that can actually benefit the earth and its inhabitants. With a bit of planning and strategy, crops can flourish without risk. Let’s dive into four alternative solutions that can help keep your gardens pest-free without the use of toxic pesticides. Biological Control This practice not only fights infestations, it is healthy for the environment! It involves attracting the natural enemies of pests and creating a habitat where they can thrive. These helpers are readily found in backyard gardens and commercial fields, and encouraging them to take up residence near produce plantings helps keep pests in check. There are many facets of biological control. Three of them involve: Attracting beneficial insects; Cover Crops; and Hedgerows. Attracting Beneficial Insects Ladybugs, nematodes, lacewings, parasitic wasps, birds, bats, and more all feed on the predators that threaten our gardens. Attracting them is as easy as planting pollen-producing and nectar sources near your crop.  For instance, wild lilacs are a favorite among butterflies and bees, who are attracted to their fragrance. With good soil, these plants require little care once they’re established and will provide a home for beneficial insects who can help control natural threats to produce. Other plant varieties that create a pollinator habitat and entice beneficial species include: Yarrow Purple coneflower Coral bells Lupine Sunflowers Foxglove Golden rod Sunflowers Beebalms There are many more options to help you build a pollinator habitat. For best results, look for flowers, plants, and herbs that are native to your area.  Cover Crops Cover crops are another method of biologically controlled pest management. Growing an alternative crop between primary harvests provides a haven for beneficial insects. Bonus: Cover crops improve soil health, control soil erosion, and can even bring in extra revenue! Peas, rye, and wheat make excellent cover crops to protect against plant threats while providing a potential extra revenue stream for farmers. Hedgerows Finally, hedgerows – rows of bushes or short trees – can be planted as a sort of fence or boundary, giving bats and birds a nesting and foraging habitat where they can thrive as they provide defense against pests.  Options that will do well as hedgerows include: Evergreen huckleberry Wax myrtle Redwood dogwood Blue or red elderberry Silk tassel Vine maple Biological control is an effective and environmentally sound way to protect plants from the dangers of pests and diseases; however, it is not a fool-proof method. When an infestation is spotted, an all-natural plant care solution like GrowSafe should be applied directly to the affected area to kill pests on contact. GrowSafe is a proprietary solution of food-grade, organic ingredients that protect the entire plant when applied properly. It can be sprayed at any time during the growing cycle and won’t harm the plant or the environment (it’s safe for pets and people too!) from root to tip. GrowSafe gives farmers and gardeners peace of mind that their produce is safely and ethically farmed. However, the best way to prevent infestations from occurring is to preventatively apply GrowSafe to crops every 6 to 10 days. Integrated Pest Management Integrated pest management, or IPM, is a sustainable method of protecting vegetation that involves tools and strategies to control pests and viruses that feed on crops. Using science-backed methods, IPM prevents pest damage and reduces a resistance to other pest-management practices while minimizing environmental risks. IPM involves many practices.  Three of them include: Companion Planting; Intercropping; and Strip and Row Planting. Companion Planting Companion planting involves interspersing crops with pest-repelling plants like garlic, which has a strong odor that can help mask the scent that attracts insects. The goal is to deter natural pests (including destructive wildlife like deer and rabbits) but it has the added benefit of protecting light-sensitive crops and even crowding out weeds that might otherwise flourish in between plants. Successful companion plants that flourish locally include: Cilantro Fennel Dill Celery Basil Marigolds  Intercropping A related IPM practice is intercropping – planting two or more crops close enough to benefit at least one of them. For instance, planting a deep-rooted crop, like eggplant or cauliflower, with one with shallow roots like onions and shallots, improves land efficiency.   Beyond providing a better balance of light, water, and nutrients, intercropping is an effective method of natural pest control because it confuses insect pests and attracts beneficial insects like bumblebees and butterflies. Threats that thrive on one crop may be challenged to find a host due to the close proximity of different plants. Intercropping also includes crop rotation, in which different crops are planted in the same field at different times of the year. Acreage with increased diversity not only keeps from depleting the soil of nutrients used for a single crop, but also makes it more difficult for insect pests to take hold and thrive.  A thoughtful strategy, like planting legumes followed by root vegetables, then fruit, followed by leafy greens, ensures soil can keep the appropriate balance of moisture and nutrients to benefit the harvests of each crop. Planting when particular pests are least active adds a layer of natural protection. Strip and Row Planting IPM also includes strip and row planting, in which two crops are either grown mixed in the same row or in adjacent rows. How is it successful? The answer depends on the crops. Insects use visual cues to find a host on which to feed; by planting two different crops close together, an insect threat may not recognize its intended target. Varying the heights of the intercropped plants, like pairing corn with cabbage, will also throw pests off the scent of the produce they seek. The practice of intercropping has an additional value: it avoids monocultures, an environment that insect pests crave for their nutrients. Growing only one crop at a time on a specific field not only results in soil degradation; it also provides a desirable home for diseases and/or pests that feed on the produce, enabling them to easily destroy an entire crop. As parasites reproduce – plants are doomed before they start. By interspersing your produce, each crop is more likely to flourish long term.  While IPM is an effective and sustainable approach to farming, it’s not fail-safe. Pests and diseases inevitably find their way to plants. However, integrating a preventative application of GrowSafe into your crop management routine will deter pests and diseases from settling in and making a home in your gardens. Soil Management for Pesticide-Free Gardening It’s a no-brainer that good plants grow in good soil. Healthy soil promotes the health of plant roots, supplies nutrients like carbon for better growth, and filters and distributes water for plants to flourish. It also plays an important role when it comes to protecting agriculture. Much like a balanced diet for humans, nutrient-rich soil gives plants a healthy foundation from which to grow. Roots and stems can absorb vital nutrition to produce antioxidants that boost a plant's defense mechanisms, making it better able to tolerate damage from plant threats. Well-controlled watering also helps soil fight off plant threats. Too much water can cause root rot, weakening the plant and providing an opening for damaging insect pests. Excess moisture is also a breeding ground for organisms.   But most plants can’t thrive in soil that is too dry. If a plant senses there is too little water, it will slow its absorption rate to retain moisture for as long as possible – which means it also limits the amount of beneficial minerals and fertilizer it absorbs. When soil becomes hydrophobic it can be enticing for pests like mites, thrips and certain types of beetles that thrive in dry environments.  You can keep your soil fertile by implementing some of the IPM practices above, like crop rotation and companion planting. It’s also recommended to amend soil with compost to strengthen soil structure, retain moisture, and improve its health. Physical Defense  Barriers like mulch, netting, and row covers provide a physical deterrent to some pests, blocking their access to tender leaves. Mulch A good organic mulch/compost blend can help prevent disaster in a few ways. The small bits of bark hold in beneficial moisture, ensuring crops have the water they need to stay healthy and thwart pests who feed on withering plant material. And if the soil has somehow become a breeding ground for pests, mulch can reduce the amount of potentially infested soil from splashing up against a plant’s stem and leaves. A final benefit? The organic matter within mulch provides beneficial microbes to support the soil and help keep vegetation strong and healthy.  Netting Netting also offers an extra layer of protection by blocking potential threats. Whether applied over young seedlings or more mature crops, a tightly woven net is an effective way to protect produce, as long as all parts of the plant are covered and the net is securely fastened to the ground. This method works best with smaller areas of crops. Row Covers Row covers work the same way as netting, blocking exterior pests before they can reach the vegetation, but are a bit more versatile. Made of a lightweight fabric much like gauze, row covers vary in thickness, lengths and widths, and can be cut to size. These provide sun and weather protection which can increase the growing season while creating a barrier against insects, just be sure to remove them when pollinating plants begin to flower. When using row covers, it’s important to visibly inspect the plants regularly to ensure no disease or infestation has taken hold. Safe, Sustainable Pesticide-Free Farming Threats to plants have existed as long as the plants themselves. While pesticides have been used since the 1960s, it took decades to understand their long-term implications on the environment. Now that the harmful effects are known, we are here to help equip farmers and gardeners with a safe and effective pest control solution that doesn’t involve toxic chemicals. GrowSafe rivals the effectiveness of the conventional chemicals that are used for general agriculture — but, unlike pesticides, its non-phytotoxic solution won’t burn plants or affect their smell or taste. GrowSafe’s food-grade ingredients make plant care safer than the fossil-grade ingredients found in Neem and mineral oils, and it is readily available, shelf stable, and poses no risk to people, plants, or the earth.  When farmers use GrowSafe in combination with the pesticide-free practices described in this article, the result is safe for consumption and the biodiversity of our planet.

If you see vegetation that looks like it’s sprinkled with baby powder or covered in cobwebs, chances are you’re seeing powdery mildew. This disease is highly infectious, and while you may not see signs of it now, it poses a constant threat to your plants. Fruits, vegetables, and berries are susceptible, along with trees and vining plants like tomatoes and grapes. Popular flowers, including some varieties of zinnia, roses, phlox, bee balm, and peony, can all fall prey to powdery mildew infections. This common, widespread disease can develop anytime during the growing season but powdery mildew doesn’t hibernate in the colder months. It survives winter weather by attaching to plant parts and debris, leaves and twigs, and hiding in the buds of infected plants. When the temperatures rise, spores are released and spread the infection – which is why treating your crops and gardens now can help prevent a severe outbreak in the spring. Read on to find out more about what causes powdery mildew, how it spreads and harms plants, and how to effectively treat it without damaging the environment. What is Powdery Mildew? A common fungal disease in the Erysiphales family, multiple species of powdery mildew affect more than 10,000 annual and perennial plants. Some varieties impact just one or two plant types while others attack a wide range of vegetation, but all types of powdery mildew require live tissue to grow and reproduce. This fungus can thwart plant growth, limit blooms, impact photosynthesis, and reduce winter hardiness. The leaves of a newly infected plant may appear as irregular, chlorotic, or have purple areas, with powdery blotches or felt-like mats before the identifiable white, powdery appearance develops. Young leaves infected by the fungus may develop scab-like lesions and become twisted as they grow, and severely infected leaves can turn yellow and fall off. When the mold infects the buds of woody species like crepe myrtle, sycamore, and fruit trees, the trunks may grow distorted. The disease takes a more impactful toll on crops, reducing yield and quality, damaging high-value plants, and affecting the appearance and taste of produce grown from infected hosts. As a result of the damage it causes, growers may plant crops differently to manage powdery mildew infections. Powdery mildew is not considered a danger to most people, although directly touching it or eating an infected plant may cause allergic reactions like sneezing and coughing. Those who are most vulnerable may experience more severe breathing difficulties after direct contact with the fungus. What is the Lifecycle of Powdery Mildew?Powdery mildew is challenging to manage due to its unique structure and year-round lifecycle that enable it to survive all weather conditions. The cycle starts with small, dark, and thick-walled structures called cleisthothecia that protect the fungus against cold temperatures. The cleisthothecia produce cylindrical spores called conidia that lie dormant until warm weather arrives. When conditions are right, the cleisthothecia release the conidia, which transmit the fungus to host plants. Once vegetation is infected, mycelium appears on the leaf surface.These small fungal threads may look like fuzzy spots and can merge with spores to coat the whole leaf, sometimes covering the length of the plant. After the fungus is established, the mycelium creates new pin head-sized cleisthothecia structures, which then release more conidia and start the cycle once again.  Powdery mildew can survive environments that would kill most other fungi. For example, this disease tolerates warm, dry conditions, as well as the humid environments preferred by other types of fungal diseases. Some fungi require water on plant leaves to grow (think, foliage that is damp with rain drops or dew) but powdery mildew doesn’t require surface moisture as part of its lifecycle. How Does Powdery Mildew Spread?The really challenging part of powdery mildew is how easily it spreads. Carried  by wind currents and spread through water or raindrops that splash onto a neighboring plant, this disease is unstoppable. The right combination of light, weather, and ventilation provide the ideal growing conditions for this fungus to rapidly infect plant leaves and stems. Powdery mildew grows best on foliage planted in shady areas with poor air circulation, and produces more spores in higher humidity environments. Because it disperses more spores as the humidity drops, infection rates increase in spring and fall, when the days are between 70 and 80 degrees and the nights are humid. Although powdery mildew can occur all season long, it does not tolerate heat well and is less common when the thermometer reaches 90 degrees and above. Unsurprisingly, the fungus thrives indoors in humid greenhouses where plants are in close proximity. Outdoors, the wind can carry fungal spores hundreds of miles and impact vegetation that is nowhere near the infected host plant. Once a spore lands on a new host, it quickly germinates and starts a new infection—sometimes in as little as 48 hours. Why Conventional Fungicides are Not the AnswerBeyond damaging soil health, affecting nearby water sources like streams and rivers, and killing beneficial insects like bees, butterflies, and ladybugs, conventional fungicides have been proven to be dangerous to people, pets, and the wildlife that feed on treated plants. Despite several strains of this mold developing treatment resistance, growers use both preventative and curative fungicides in the battle against powdery mildew. Both varieties contain chemicals that may be unreliable at controlling the disease and can harm the plant and/or the environment. Copper- and sulfur-based preventative fungicides are popular options. Those that are copper based can be somewhat effective, but this fungus requires frequent reapplication. Used regularly, copper can build up in the dirt, damaging the foliage and negatively impacting the nearby soil. Preventative mixtures that include sulfur increase the potential for hydrogen sulfide production. When applied on days with temperatures around 90 degrees, sulfur can damage the tissues of the host plant. It can also be lethal to some of the natural enemies that help control this fungus’ spread. Powdery mildew cannot be cured but some compounds called curative fungicides, contain chemicals like acetimides, dicarboxymides, and sterol inhibitors, and are used post-infection to prevent further pathogens from developing. To be effective, they must be applied within 24 to 72 hours of the infection—which presents a challenge because signs of powdery mildew are not typically visible for several days. Some growers use Neem oil to attempt to manage this disease but, not only has it not been proven effective, it can cause the host plant internal damage, leaf burn, and stress symptoms. Neem oil is deadly to all insects that come in contact with it, may cause stomach irritation for those who eat foods treated with it, and humans who touch it may experience skin reactions. Overusing Neem oil can lead to runoff and accumulation in waterways, negatively impacting fish and other aquatic life. Safe Solutions to Your Powdery Mildew Problem No matter how it is treated, powdery mildew will inevitably spread; its tenacity guarantees it. However, there are actions you can take to effectively manage this disease. If you see signs of infection, remove the diseased parts of the plant (and throw them away versus composting) and ensure you disinfect any garden tools that may have come in contact with the fungus. Long term actions include using Integrated Pest Management (IPM) practices, like choosing plants typically unaffected by powdery mildew, practicing crop rotation and soil management, all help. How and where you plant can make a significant difference: planting in an area with full sunlight with well-drained soil makes infection more difficult. Leaving space between plants provides more light penetration, decreases moisture, and improves air flow – reducing the humid environment in which powdery mildew thrives. There is one additional powerful alternative to controlling powdery mildew that is successful and sustainable: GrowSafe. GrowSafe is an effective curative treatment that works by coating a plant’s surface, forming a shield against fungi, pests, and diseases. Its oils naturally inhibit spore germination, which is why it is also used as a preventative treatment to protect plants from the invasive conidia seeking a host. Because it’s made from biodegradable, food-grade ingredients (corn, soybean, sunflower and coconut oils and citric acid), GrowSafe is 100% safe for people, pets, and the environment. It is safe to use on all plants and it will not alter their taste or smell. Plus, it can be sprayed during any point in the growing cycle. More so, it’s completely safe for beneficial insects! For the best results, apply GrowSafe during dry conditions and reapply after it rains. While nothing can fully eradicate powdery mildew, a combination of IPM practices and the regular use of GrowSafe can help protect your farms and gardens from this rampant fungus. Prime months to begin preventative measures are typically January, February, and March, though prevention is always better than a problem. No matter the time of year, we recommend beginning your powdery mildew management practices today.

As a plant enthusiast, you’ve likely encountered pests or diseases that have impacted the health of your potted plants or garden; this is part and parcel of plant ownership. Plants face plenty of threats, from insects (aphids, mealybugs, whiteflies, beetles, and more) to viruses, bacteria, and fungi. Without treatment, entire crops can be wiped out with staggering costs: Plant diseases cost the global economy $220 billion in 2023, and invasive insects did $70 million worth of damage. Products that prevent, reduce, or destroy pests have been around since as early as the 8th century BC, when salt sulfur compounds were used to protect crops threatened by insects and mites. These pesticides have evolved over time, and today, you’ll find a range to choose from. Each has different properties and can vary in its cost, effectiveness, and environmental impact. When it comes to pesticides there are three main chemical groups that defend and protect against harmful pests. These include systemic, translaminar, and direct chemicals. In this article we discuss each group to help you determine which is best for you. Systemic Pesticides: Treatment From Within   Like the name implies, systemic pesticides impact the biology of the plant. The pesticide works its way through the plant’s vascular system as it transports the chemical from roots to tip, absorbing into its tissues, impacting the plant’s stem, leaves – including new shoots – the flowers, fruit, and even the pollen it produces. Systemic pesticides are water-soluble and can be added to soil for plants to absorb. This chemical group can provide a strong defense against diseases and insects at any stage of growth. Because it is applied via the soil, a systemic pesticide mixes with the sap of the plant, which kills pests and fungus that feed on the sap. With this chemical working inside the vascular system, it is within the plant tissue – meaning it cannot be washed off or removed. Plants treated with systemic pesticides are toxic, not only to the pests they target but also to beneficial insects and pollinators, and any animal or human ingesting the plant and its fruit. This has dangerous repercussions on the entire insect population, and are particularly damaging to bees. Systemic pesticides include neonicotinoids, which, even in low concentration, are toxic to bumble bees, honey bees, and solitary bees. They don’t just harm the existing population: systemic pesticides have been shown to impair reproductive capacity, flight, navigation, learning, and the bees’ immune responses. This has disastrous implications for future bee populations—and with it, the environment as we know it. Because these chemicals are water soluble, they seep into and contaminate the soil, groundwater, nearby streams, and waterways, poisoning pollinators, birds, fish, and aquatic life that come in contact with them. Translaminar Pesticides: Topical Treatment Unlike systemic pesticides that become embedded in the tissue of the entire plant, translaminar pesticides remain localized in one area of the plant — typically the leaves. Translaminar chemicals are applied to the foliage, where they stay to kill the pests that feed on the leaves.  By remaining in the leaf tissues, these pesticides provide an ongoing fight against several types of plant-eating pests and tend to last longer than contact pesticides. Translaminar solutions are also less expensive than systemic pesticide varieties and while they are less effective, they still pose a threat to both humans and the environment. Beneficial insects like butterflies, ladybugs, and bumblebees are harmed when they come in contact with the residue on the leaves. And when the pesticide is inside the leaf tissue, it cannot be washed off or removed, making it toxic to humans and animals that may eat the leaves.  Direct Pesticides: Targeting the Source Systemic and translaminar pesticides protect against plant threats from the inside out. Direct pesticides are applied directly to an area of a plant with an existing infestation to kill pests and fungi and are an effective and quick way to protect against additional damage. These pesticides kill on contact, then linger on the plant surface to repel other invaders, but their residue can be rinsed off, making produce that’s been treated with these chemicals somewhat safer to eat depending on the ingredients of the pesticide.  If developed with toxic chemicals, direct pesticides can still impact the environment, leaching into soil from rain and watering, impacting groundwater and affecting the health of nearby streams and aquatic life. These pesticides are harmful to targeted pests, but also pose a risk for humans, pets, and beneficial insects, pollinators, and fish. Even substances like Neem oil, a biodegradable, non-toxic direct pesticide that has been used for decades, can be harmful to plants, people and the environment. Neem oil can burn plant foliage and should not be sprayed on recently transplanted or stressed plants. It can contaminate plants, reduce their yield, and change their smell and taste.  Regardless of which type of pesticide is used – systemic, translaminar, or direct – the targeted pests and viruses can build an immunity to the chemicals, ultimately making pesticide treatment less effective. GrowSafe: Stops Pests & Diseases Safely Fortunately, there is one effective pest treatment that is safe for people, pets, the planet, and the plants. GrowSafe is a product applied directly to infested plants that kills pests and disease on contact. GrowSafe is a biodegradable product made from food-grade corn, soybean, sunflower and coconut oils and citric acid. The application of the product thoroughly coats impacted plants with this proprietary mixture and suffocates pests and diseases, killing them on contact. Due to its all-natural ingredients, GrowSafe won’t harm the environment if it gets into the soil and, importantly, the product is safe for people, pets, pollinators and beneficial insects that come into contact with the treated plant. Further, treatment will not change the smell or taste of herbs and botanicals, fruits, or vegetables. Integrated Pest Management: One More Tool in the Arsenal Environmentally responsible crop management requires more than safely controlling unwanted pests and diseases. Integrated Pest Management (IPM) practices promote sustainable farming while promoting biodiversity, and involves integrating several methods working together to control crop damage. IPM involves strategies like dense crop planting to minimize the space for weeds to grow. Planting seeds close together helps the plants crowd out weeds, which also maximizes yield and results in better higher revenue. Another element of IPM involves strip cropping – planting different crops in strips of the same plot of land to minimize pests destroying an entire crop. Also known as intercropping, this practice helps control pests who find it difficult to locate a host plant. An additional benefit: This type of farming may actually attract and maintain beneficial insect populations.  Timing is everything in IPM. By timing the planting season to avoid peak pest infestation periods, the crop avoids the worst of the onset and is less likely to suffer damage – yielding healthier plants that require less treatment. Sustainable farming promotes biodiversity. When integrated with IPM practices, GrowSafe helps control pests and keep the soil fertile, while protecting the plant and the environment. By combining the all-natural GrowSafe pest treatment with the ecologically balanced farming practices of IPM, biodiverse ecosystems are better balanced and preserved -– controlling damaging infestations while protecting our soil and water systems and ensuring our food is safe and stable. The Bottom Line We’ve looked at a variety of ways to treat pests and infestations that infect and destroy plants. These threats wreak havoc on crops. But using toxic systemic, translaminar, or direct pesticides causes long-term damage that lasts far beyond the life of an individual plant and can have irreversible consequences on our climate. Using a non-toxic direct pest treatment that is as effective as it is safe can be the difference between a rich biodiversity that thrives and a weakened ecological scenario in which current and future populations are adversely impacted. GrowSafe, applied directly to the infected area of a plant, zeroes in on the targeted pest without damaging the plant itself or those who come in contact with any part of it. Safer soil, water, and food systems support our health and our environment.  Familiarizing yourself with the varieties of pesticides and understanding how they work will help you make an informed decision.

The two-spotted mite, also known as the spider mite (Tetranychus urticae), is a common pest that can wreak havoc on a wide variety of plants. Recognizable by the two distinctive dark spots on their bodies, these tiny arachnids are often overlooked until significant damage has occurred. Let's delve into what makes these mites a formidable foe and how you can protect your plants from their detrimental effects. Identification Physical Characteristics Two-spotted mites are minuscule, usually less than 1 mm in size, making them hard to spot with the naked eye. They are typically pale yellow or green, with two dark spots on their back. Using a magnifying glass can help in identifying these pests on your plants. Signs of Infestation One of the first signs of a two-spotted mite infestation is a stippling effect on the leaves. As these mites feed on plant sap, they create tiny, light-colored spots that can eventually lead to bronzing or yellowing of the leaves. Severe infestations can cause leaves to dry up and drop off. You might also notice fine webbing on the undersides of leaves or between plant stems. Lifecycle and Behavior Reproduction Two-spotted mites reproduce rapidly, especially in hot and dry conditions. A single female can lay hundreds of eggs over a few weeks, leading to exponential population growth if left unchecked. The entire lifecycle from egg to adult can be completed in as little as a week under optimal conditions. Feeding Habits These mites pierce plant cells to feed on their contents, draining vital nutrients and causing significant stress to the plant. They prefer the undersides of leaves, where they are protected from direct sunlight and predators. Prevention and Control Cultural Practices Regular Inspection: Frequently check your plants, especially the undersides of leaves, for early signs of mites. Maintain Humidity: Two-spotted mites thrive in dry environments, so keeping humidity levels up can help deter them. Cleanliness: Remove any infested plant material and keep the garden free of debris where mites can hide. Biological Control Predatory Mites: Introducing natural predators, such as Phytoseiulus persimilis, can help keep two-spotted mite populations in check. Beneficial Insects: Ladybugs and lacewings also feed on two-spotted mites and can be beneficial in an integrated pest management approach. Chemical Control Miticides: There are specific miticides available that target two-spotted mites. Always follow the manufacturer's instructions and consider the impact on beneficial insects. Insecticidal Soaps and Oils: Oil and insecticidal soaps can be effective against mites without being too harsh on the environment. These options are particularly useful for smaller infestations. Conclusion The two-spotted mite may be tiny, but its impact on plants can be substantial. By understanding its behavior and implementing a combination of cultural, biological, and chemical controls, you can protect your garden from these persistent pests. Regular monitoring and early intervention are key to keeping two-spotted mite populations under control, ensuring your plants remain healthy and vibrant.
