Brown leaf hopper (BLH) is a tiny insect that can be a major problem for brinjal crops. These pests damage the plants causing yellowing, wilted leaves and stunted growth. If not controlled properly and in a timely manner, BLH can cause significant yield losses. So, how can we control brown leaf hopper in brinjal crops? Here are a few effective methods:
1. Cultural Control
Clean cultivation practices like removing the fallen debris and uprooting of old plants will help to reduce the BLH population. Ensure to plow and clean the field before planting to destroy the nymphs and eggs in the soil. Intercropping with non-host crops such as maize, pigeon pea, etc. can help to reduce the pest population.
2. Biological Control
Release natural predators like spiders, ladybirds, lacewings, and praying mantis in the affected area. These insects feed on BLH nymphs and adults, reducing their population and controlling the spread of the pest.
3. Chemical Control
Use of pesticides is a common method for controlling BLH in brinjal crops. The commonly used pesticides are Imidacloprid, Thiamethoxam, Acephate, etc. Spray the pesticides in the evening or early morning to avoid damaging the other beneficial insects.
4. Natural Remedies
Herbal extracts such as neem oil, garlic oil, and chilli pepper spray can be used to repel and control BLH. A mixture of neem oil, water and some liquid soap can be sprayed on the affected plants which prevents the BLH from damaging the crops.
5. Regular Monitoring and Management
Regular monitoring of the plants is crucial to identify the BLH infestation at an early stage. If caught early, the pest can be controlled with less effort and expense. Pruning the damaged leaves and branches will help to prevent the spread of infestations.
In conclusion, the effective control of brown leaf hopper in brinjal crops relies on the implementation of the above methods. By following good agricultural practices and using a combination of cultural, biological, chemical, and natural remedies, you can manage and control brown leaf hopper in your brinjal crop. Remember, timely identification and swift action are the keys to controlling BLH effectively.
