Papaya Ring spot Virus is one of the most destructive infections which is mainly spread by mechanical activities through the sap.

Papaya Ring Spot Virus Symptoms

The greenish mosaic pattern on leaves can also be distorted with reduced leaf area. Fruits and flowers may drop. Patches appear on the fruits as well with some bumps on them due to nutrient deficiency. The characteristic ring spots are seen on the fruits.

Preventive Measures

The most effective preventive measure is vector control using insecticides and micronutrient sprays. Spreading plastic silver-coloured mulch is another way of their management. Water-soaked oil patches appear on petioles. Using resistant or clean seedlings is another ideal option for prevention.

Leaf curl virus or geminivirus is a common microbe attacking crops such as chilli that cause major damage to the plants and their yield. They can be controlled via cultural practices and preventive measures. Here are some tips that can help you get some control over this virus and protect your crops.

Symptoms

Curling of the leaf margins towards the midrib is the most distinctive symptom. The leaves can be deformed and stem with shortened internodes leading to stunted growth. The flower buds could abscise or with no pollens.

Preventive Measures

Since this is a viral disease there are not many effective preventive measures. But some cultural practices and other mechanical methods are capable of keeping the virus away to an extent.

• Completely eliminate the affected plants by either burning or burying them deep under the soil.
• Do not do monoculture of chilli plants as it can escalate the infection.
• Use disease-free seeds and plant as much as possible and treat the seeds with fungicides before planting.
• Covering nursery beds using nylon can also reduce viral infections in the younger stage.

Chemical Control

• Tata Surplus Micronutrients Fertilizer contains all the necessary micronutrients to make the plant better resistant to infections. It promoted healthier growth of the plants and quality flowering and fruits as well. Mix 2 ml in one litre of water and apply 2-3 times at an interval of 25-30 days and 15 days.
• Sambrama Micronutrient Fertilizer comes with NPK in the required amount along with some secondary nutrients and micronutrients, mostly in chelated form. It comes in tablet form which you need to dissolve in 15 litres of water. Spray the mix on both sides of the leaves.

Add 3-4 ml of the liquid in one litre of water to spray it on the plants.

Conclusion

Viral infections such as leaf curl of chilli cannot be treated after infection. The only way is to make the plants resistant to such attacks. The best course is to provide all the necessary nutrients to improve natural immunity and thereby make the plants self-reliant.

Downy mildew is a type of fungal disease caused by water mould. This fungus can attack a variety of plants, specifically gourd crops. The affected plants could potentially cause economic loss to the farmers. Prevention is the key to controlling this disease as it can attack any part of the plant from flowers, leaves, fruits, etc.

Symptoms

• The upper surface of the leaves shows pale yellow or green coloured spots that later turn brown.
• Even though angular leaf spot is often mistaken to be this fungal disease, there is very little difference between these.
• Downy mildew is more prevalent in wet and humid conditions. It can spread by air, water splashes and even through human hands and gardening tools.

Preventive Measures

• Use resistant varieties of the plants wherever possible and buy the plants and seeds only from reputed nurseries.
• Scout the affected plants immediately and pack them in plastic bags and drop them in thrash. Do not use such plants in the compost pile.
• Remove moisture by allowing more air circulation. Timely pruning can make way for better air circulation.
• Do not water the plants from the top. Instead, use irrigation methods that water the roots rather than the leaves.

Chemical Control

• Melody Duo Fungicide contains Iprovalicarb and Propineb to prevent disease and promote healthy yield. It can act on several fungal strains and is compatible with young leaves and shoots to prevent spore formation by the fungus. Mix 3-4 gm in one litre of water.
