Preventing and Treating Common Tomato Diseases

Preventing and treating common tomato diseases is essential for maintaining healthy plants and ensuring a successful harvest. Here are some tips to help you prevent and manage common tomato diseases: Choose disease-resistant varieties: Select tomato varieties that are known for their resistance to common diseases in your area. Look for labels or descriptions indicating resistance to specific diseases such as Fusarium wilt (F), Verticillium wilt (V), or tomato mosaic virus (TMV). Rotate your crops: Avoid planting tomatoes and related plants (such as peppers, eggplants, and potatoes) in the same spot year after year. Practice crop rotation by moving tomatoes to different areas of your garden each season. This helps prevent the buildup of soil-borne diseases. Provide proper spacing: Plant your tomato seedlings with adequate spacing to promote good air circulation. Proper spacing helps prevent the spread of diseases that thrive in damp and crowded conditions. Use clean tools and equipment: Start with clean gardening tools and equipment to prevent the introduction and spread of pathogens. Clean your tools with a disinfectant solution before and after use, especially if you've been working with infected plants. Practice good watering practices: Water tomato plants at the base and avoid wetting the foliage. Overhead watering can promote the spread of fungal diseases. Use drip irrigation or a soaker hose to deliver water directly to the soil. Mulch around plants: Apply a layer of organic mulch around the base of tomato plants to suppress weed growth and maintain consistent soil moisture. Mulch also helps prevent soil-borne diseases from splashing onto the plants during watering or rainfall. Remove affected plant parts: Promptly remove and destroy any infected or diseased plant parts, including leaves, stems, or fruits. This helps prevent the disease from spreading to healthy parts of the plant. Use proper fertilization: Avoid excessive nitrogen fertilization, as it can promote lush foliage growth but make plants more susceptible to diseases. Use a balanced organic fertilizer or compost to provide necessary nutrients without overstimulating vegetative growth. Monitor for pests: Pests can weaken plants and make them more susceptible to diseases. Regularly inspect your plants for signs of pest infestation and take appropriate measures to control them. Apply organic fungicides: If necessary, use organic fungicides to manage fungal diseases. Copper-based fungicides or those containing Bacillus subtilis can be effective against diseases such as early blight and powdery mildew. Follow the product instructions carefully. Practice good garden hygiene: Keep your garden clean and free of plant debris, which can harbor diseases. Dispose of infected plant material properly, and regularly clean up fallen leaves or fruits. Monitor and act promptly: Regularly monitor your tomato plants for any signs of disease, such as yellowing leaves, wilting, or unusual spots. Early detection and immediate action can help prevent the disease from spreading and causing significant damage. By following these preventive measures and promptly addressing any disease issues, you can increase the chances of a healthy tomato crop and enjoy a bountiful harvest. Read the full article

Trichoderma Bio Fungicide in India for Soil Born Diseases Management

Trichoderma fungus is a beneficial that helps to protect your plants against molds and bacteria. These tough little funguses are standing up against root rot and gray mold, protecting from loss of your crops. They create a barrier that makes it impossible for harmful bacteria and pathogens to pass through. Trichoderma surrounds the roots of your plant releasing compounds that activate their natural systems of defense.

Trichoderma bio fungicide is most effective for all plant and vegetable forms such as cauliflower, peas, sunflower, brinjal, coffee, tea, ginger, turmeric, pepper, betel vine, cardamom cotton, tomato, chillies, potato, citrus, onion, groundnut etc. Trichoderma fungus may suppress the growth of the pathogen population in the rhizosphere through competition and thus reduce disease development.  It produces antibiotics and toxins like trichothecin and Trichodermin, a sesquiterpine that has a direct effect on other organisms.

A dynamic growth of biological trichoderma viride fungicide overshadows the pathogenic fungi, which are overpowered and prevented from infecting the plants. They can be blocked and managed by different methods before pathogens attempt infection by germinating seeds or roots. They have developed various mechanisms for both attacking other fungi and enhancing plant and root growth such as mycoparasitis, antibiosis, nutrient or space competition, stress tolerance through increased root and plant production, inorganic nutrient solubilization and sequestration.

Benefits of Trichoderma Bio Fungicide

 Disease Control: Trichoderma is an effective biocontrol agent that is commonly used in soil born diseases. It has been widely used against pathogenic fungi of various genera, i.e. Fusarium, Scelerotia, Phytopthara, etc.

Plant Growth Promoter: Trichoderma strains are solubilizing micronutrients and phosphates. The application of plants of Trichoderma strains increases the number of deep roots, thus increasing the ability of the plant to withstand drought.

Biochemical Elicitors of Disease: It is recognized that trichoderma strains induce resistance in plants. It is now known that three groups of compounds are generated by Trichoderma and induce plant resistance. Such compounds induce the development of ethylene, hypersensitive responses and other reactions in plant cultivars related to protection.

Transgenic Plants: The introduction of Trichoderma endochitinase gene into plants such as tobacco and potato plants has improved their fungal growth resistance.

Bioremediation: In the bioremediation of soil polluted with pesticides and herbicides, trichoderma strains play an important role. These have the ability to kill a number of insecticides, including organochlorines, organophosphates and carbonates.

Trichoderma bio-fungicide is used to protect crops such as cotton, soybean, sugar cane, sugarbeet, eggplant, red gram, bengal gram, banana, cardamom etc. You do not use any chemical fungicide after application of Trichoderma for 4-5 days. Trichoderma biofungicide is compatible with biofertilizers like Rhizobium, Azospirillum, Bacillus Subtilis and Phosphobacteria. Trichoderma can be added to metalaxyl or thiram-treated plants, but not mercurials. It can be used as a tank combination of organic fungicides.

How to stop fusarium wilt

What is Fusarium wilt on Watermelon?

Fusarium wilt is a common and destructive fungal disease that affects many plants, including tomatoes, potatoes, peppers, eggplants, and ornamentals. Fusarium oxysporum, a soil-borne fungus, is the cause of it. This fungus enters the plant through the roots and spreads up to the vascular system, blocking water transport. As a result, the plant wilts, even when soil moisture is adequate.Fusarium wilt is difficult to control as quickly as plant life are infected. Therefore, prevention is critical in areas prone to this disease.

Causes and Symptoms of Fusarium Wilt

Different formae speciales or races of Fusarium oxysporum that are host-specific are what cause fusarium wilt.The fungal spores can live to tell the tale in soil or plant particles for years. Any damage to the roots from cultivation, insects, nematodes, etc. creates an entry point for the fungus. Common symptoms include wilting of leaves and vines during the day, then recovery at night. Wilting increases over time until the whole plant collapses. Discoloured vascular tissue may be seen when stems are cut. Plants often have stunted growth, yellowing leaves, and reduced yields.

Effects of Fusarium Wilt

Fusarium wilt can lead to major economic losses in food and ornamental crops.It influences each the first-class and amount of yields. Infected plants either die prematurely or have lower yields and smaller fruits. They are also more susceptible to attack by other pathogens. Fusarium wilt spreads quickly between fields, carried by wind, water, and contaminated equipment. Once present in the soil, the fungus can persist for many years. Good management practises are required to prevent the buildup of inoculum.

Preventing Fusarium Wilt

Choosing Resistant Varieties The most effective strategy is to select varieties with genetic resistance to Fusarium wilt races in your area. Resistant rootstocks are available for some species, like tomatoes and melons. Grafting susceptible scions onto resistant rootstocks helps protect plants. Over time, new mutant strains of the pathogen can however overcome resistance.

Crop Rotation

Rotating fields to non-host crops like small grains, grasses, or corn for 2-3 years helps disrupt the disease cycle and reduce inoculum. Avoid planting the same family of crops successively. For example, rotate tomatoes with beans or onions rather than potatoes or eggplants.

Soil Solarization

Solar heating soil under plastic mulch during hot summer months can help reduce fungal pathogens and nematodes. Temperatures of 140°F at 6 inches of depth must be maintained for at least 3–6 weeks. This may not eradicate the fungus but it can lower the inoculum.

Soil pH Management

Fusarium wilt is generally less prevalent in acidic soils. Adding elemental sulphur to maintain a soil pH between 6.0 and 6.5 can help suppress this disease.Avoid immoderate liming, which promotes Fusarium wilt.

Treating Fusarium Wilt

Pruning Infected Parts

Prune out and break visibly inflamed plant parts. This can slow disease spread. Sterilise pruners after each cut with a bleach solution to avoid spreading the fungus. Remove entire plants only if most of the vascular tissue is discoloured.

Fungicides

Apply fungicides like TRIANUM SHIELD as a protective spray several times per season, especially after transplanting. Combine with disinfectants like thymol during early infection. Systemic fungicides are absorbed and distributed through the vascular system. However, their effectiveness is limited once extensive blockage occurs.

Biological Controls

Beneficial microbes like TRICHODERMA HARZIANUM and Bacillus subtilis help protect roots from infection. Apply these preventively as a root dip at planting. Several studies show that combining biologicals with fungicides enhances control. Mycorrhizal fungi improve stress tolerance and induce systemic resistance.

Soil Amendments

Mixing compost high in beneficial microbes before planting has reduced Fusarium wilt severity. Amending the soil with chitin and kelp stimulates chitin-eating bacteria that attack the fungal cell walls. Mustard seed meal releases toxic gases during decomposition that inhibit pathogen growth.

Identifying and Monitoring Fusarium Wilt

Look for Early Symptoms

Scout fields frequently to detect initial symptoms like leaf yellowing and minimal wilting on one side. Check for vascular discoloration by cutting the stems. Send samples promptly for lab diagnosis to confirm Fusarium wilt infection early.

Send Samples for Testing

Submit diseased plant samples to a diagnostic lab for isolation and identification of the specific form of the fungus. This determines which races are present so appropriate resistant varieties can be selected in the future.

Compare Healthy and Infected Plants

Dig up and inspect the roots of wilting plants for lesions or reduced feeder roots. Compare cross-sections of stems from healthy and symptomatic plants to observe vascular browning in the latter. Monitoring disease progression helps track the effectiveness of management tactics.

Long-Term Fusarium Wilt Management

Crop Rotation Plan

Develop a planned sequence for each field using 3–4-year rotations with non-host crops. Track crop history for each site to avoid repeating susceptible species. Clean equipment thoroughly when moving between infected and uninfected fields.

Resistant Varieties

Choose resistant or grafted cultivars adapted for local conditions each season. Monitor for new virulent strains that may overcome resistance. Proactively breed and select cultivars with durable, broad-spectrum resistance.

Soil Health

Build soil organic matter, beneficial microbes, and proper pH and nutrients to promote vigorous plant growth and increase disease resistance. Test the soil regularly to correct deficiencies and imbalances. Add compost and organic amendments.

Conclusion

Key Takeaways

Warm weather is a favourable environment for the harmful vascular disease Fusarium wilt. Prevention is essential, as infected plants cannot be cured.

Employ resistant varieties, clean transplants, crop rotation, soil solarization, fungicides, and cultural practises to avoid Fusarium wilt.

Promote vigorous growth with proper soil management. Scout for early symptoms. Remove and destroy infected plants promptly.

Disinfect tools and equipment between uses. Develop integrated, long-term management plans tailored to each farm.

Safe Selections 

At times, choices invulnerable to fine-grained buildup may be advertised. In the event that accessible, plant safe determinations of melon, cole plants, cucumber, melons, peas, pumpkins, and furthermore squash. On the off chance that you develop extra weak reaches, you may need to take control methodology. 

Social Practices 

Plant in warm zones as high as attainable, give great air dissemination, just as avoid utilizing overabundance manure. A decent decision is to utilize moderate delivery plant food. Costs sprinkling may help in lessening fine-grained mold since spores are wiped off the plant. Regardless, overhead sprinklers are not for the most part suggested as a control procedure in veggies on the grounds that their use may add to other bug inconveniences. 

Fungicide Application 

In certain circumstances, particularly in the assembling of inclined cucurbits, fungicides may be required. Fungicides work as protectants, eradicants, or both. A protectant fungicide shields against pristine diseases from occurring while an eradicant can slaughter a current contamination. Apply protectant fungicides to profoundly inclined plants preceding the infection appears. Utilization eradicants at the most punctual indications of the condition. When buildup development is broad, control with any sort of fungicide winds up being harder. The things definite underneath are for home nursery use. Business cultivators ought to talk with the UC Parasite Monitoring Standards. 

Fungicides 

Various least-harmful fungicides are accessible, including green oils, neem oil, jojoba oil, sulfur, just as the organic fungicide Serenade. Except for the oils, these materials are predominantly preventive. Oils work best as eradicants yet similarly have some protectant task. 

Oils 

To wipe out light to humble grainy buildup contaminations, utilize a cultivating oil like Saf-T-Side Spray Oil, Sunspray Ultra-Fine Spray Oil, or one of the plant-based oils, for example, neem oil or jojoba oil (e.g., E-rase). Be careful, in any case, to never utilize an oil splash inside about fourteen days of a sulfur shower or plants may be injured. Also, oils should never under any circumstance be utilized when temperature levels are over 90 ° F or to dry season focused on plants. A few plants might be considerably more sensitive than others, be that as it may, and the span needed among sulfur and oil splashes might be likewise more; consistently look for guidance from the fungicide tag for any sort of novel safeguards. Best landscape company in delhi

Sulfur 

Sulfur things have been utilized to oversee fine-grained form for quite a long time however are just proficient when applied before condition signs and side effects appear. The absolute best sulfur things to utilize for fine mold control in gardens are wettable sulfurs that are uncommonly evolved with surfactants equivalent to those in dishwashing cleaning specialist (e.g., Safer Yard Fungicide) Nonetheless, sulfur can be harming to some crush and furthermore melon determinations. To forestall hurting any plant, don't matter sulfur when air temperature is close or more than 90 ° F and don't make a difference it inside about fourteen days of an oil splash. Other sulfur things, for example, sulfur earth, are substantially more testing to utilize, irritating to skin and eyes, just as limited as far as the plants they can securely be used on. Copper is additionally accessible to control fine-grained shape yet isn't actually dependable.

Fighting Vineyard Fungal Disease, With and Without Copper

For organic vintners, copper-based sprays have proven to be the most effective tool for combatting downy mildew. Prevalent in regions with warm, humid springs and summers, the fungal disease can wipe out entire vintages. Left untreated, it can even kill grapevines. For organic producers in large parts of northern Europe and the eastern U.S., copper is therefore not just a tool, but a necessity.

In January 2019, the European Commission enacted a new law lowering the amount of copper that could be used in organic farming. The ruling came after the European Food Safety Authority published a high-profile risk assessment, which showed that copper compounds pose risks for farm workers, animals, and vineyards.

In regions such as Bordeaux, organic producers must now adapt to these new limits while still effectively combating downy mildew. Otherwise, the only options are switching to synthetic chemicals or accepting significant and costly yield reductions. There may be some hope on the horizon, though: Numerous trials around the world are testing whether new, organically acceptable fungicides could supplement or even one day replace copper.

To find out how organic vintners are coping with the new limits, and to see what the future holds for regions susceptible to downy mildew, VinePair spoke with multiple Bordeaux producers and viticultural scientists with knowledge of potential innovations.

While downy mildew is by no means the only challenging fungal disease vintners face, it is among the most significant. “If left unchecked, it has the potential to kill your vine [because] it reduces [the vine’s] ability to store the nutrients it needs to get through winter,” explains Dr. Katie Gold, assistant professor of grape disease ecology and epidemiology at Cornell University. ”Many of the other fungal diseases will impact crops within the season, but they won’t necessarily kill the vine.”

Since the 1800s, vintners have combated downy mildew with a copper solution called bouillie bordelaise. Otherwise known as Bordeaux mixture, the solution contains a mix of copper sulfate, lime, and water. While allowed in organic viticulture, prolonged use of high concentrations of Bordeaux mixture (and other copper-based solutions) can be extremely harmful to vineyards.

“In Europe, where they use it extensively, copper can leave heavy metals on the surface of the soil, which can not be metabolized by microorganisms,” says Dr. Akif Eskalen, plant pathologist and extension specialist at UC Davis.

When copper accumulates, it affects the concentration of useful microorganisms, the pH of the soil, and ultimately grapevine growth, Eskalen explains. In regions like Bordeaux, where copper solutions have been sprayed for over a century, this can be a common problem. The issue is further compounded by non-organic producers who use copper alongside chemical herbicides, a combination that can be toxic for soils.

But elsewhere in the world, in regions where downy mildew is not as common, copper accumulation is not an issue.

In 2019, grower-led organization Organic Winegrowers New Zealand (OWNZ) commissioned a soil assessment study, measuring the level of copper in soils after eight years of organic management. “Our independent researchers found that there was no sign of elevated copper levels in the organic vineyard soils after eight years of organic management,” says Rebecca Reider, OWNZ’s national coordinator. “We weren’t surprised by this result, but we were happy to receive it.”

How Producers Are Adapting in Regions With High Downy Pressure

This year marked the second vintage that European organic producers have been adapting to the new copper limits. Previously, vintners could spray up to 6 kilograms per hectare per year (around 5 pounds per acre). Now, they can apply 4 kilograms per hectare per year (around 3.5 pounds per acre). The law does allow levels to be taken over a seven-year average, meaning that in particularly wet vintages, producers can exceed that limit.

This year has proven to be one such vintage in Bordeaux.

Pierre Cazeneuve, owner of Château Paloumey in the Médoc, describes 2020 as one “one of the most difficult mildew pressures” he’s seen in the last 10 or 15 years. Cazeneuve has been practicing organic farming for five years, and when the copper reductions were first announced, a vintage such as this was his worst nightmare. But with just one month remaining where he will potentially have to spray, he’s surprised to find that he has so far only used half of his yearly allowance.

How has he adapted? Firstly, Cazeneuve dropped the concentration of copper he’s including in his sprays by around 25 percent. “Regularity and accuracy of spraying seem to be the best solution rather than quantity,” he says. Cazeneuve also started essential vineyard work as early as possible, and has been vigilant in keeping on top of processes that improve aeration. He’s also kept a close eye on the weather, tracking it with four different cell phone apps to ensure he’s spraying at least a day in advance when rain is on the horizon, though this is nothing new. “Some people look at Twitter, I look at weather forecasts,” he says.

While his new regime has increased his workload significantly, Cazeneuve now believes the lower copper limits seem feasible. But he stresses that it will take a few more years and statistical data from around Bordeaux to prove whether that is the case for all organic producers.

Others need less convincing. Matthieu David-Beaulieu, winemaker at St. Emillion’s Château Coutet, agrees that it’s been a particularly trying vintage. But at no point has he worried about exceeding the maximum copper limits.

Château Coutet has been certified organic since 2012, and practiced organic farming for many years before that. David-Beaulieu says the experience built up in this time, as well as the health of his vineyards, have proven effective during this challenging vintage. But for those who recently switched to organic farming, it’s been a process of learning. “They want to use a lot [of copper] to protect [the vines], they are not used to spraying such small amounts,” he says.

Copper Alternatives on the Horizon?

For producers wishing to reduce their copper use, there are currently only a handful of commercially available organic products. Examples include EF 400, which contains a mix of essential oils, and Certis USA’s OSO. But these products work only as a supplement, and are not a full-blown replacement for copper.

Around the world, trials are taking place to test the efficacy of other solutions. In Italy, some success has been found using chitosan, a naturally occurring polymer that’s extracted from the outer shells of crab and other shellfish. Laminarin, a carbohydrate extracted from brown algae, also appears to be a potentially effective supplement.

Recent studies using a microorganism called bacillus subtilis have also proven effective at inhibiting the growth of fungi such as downy mildew. But the success of biocontrol agents such as this is limited by climate, weather conditions, and location of plants, says U.C. Davis’s Eskalen.

“I’ve done a lot of research with new products, but the main problem is efficiency,” says Etienne Laveau, a Bordeaux-based consultant who specializes in organic viticulture. Laveau says that, at best, the products he’s tried have been 40 percent as efficient as copper — and that was in vintages that were much less challenging than 2020.

Laveau agrees that alternatives and supplements need to be found. But for now, he says, there remains only one path forward: “We hope that we can continue to use copper for a long time — maybe with other products to help us, but without copper it would be impossible.”
