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.
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.
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.
