Sure, I can provide an article on Brown plant leafhopper management in paddy.
Brown plant leafhopper (BPH) is one of the most common pests of paddy. It is a small, brown-colored insect that feeds on the sap of rice plants and transmits viral diseases. BPH infestation can lead to stunted growth, yellowing of leaves, and reduced yield. Here are some management practices that can help control BPH infestation in paddy:
1. Cultural control: Proper field sanitation is important to control BPH infestation. Maintain proper drainage, avoid waterlogging, and remove weeds that provide a breeding ground for BPH. Plant resistant varieties if available.
2. Chemical control: Insecticides can be used to control BPH population. However, it is advisable to use them in combination with cultural practices. Application of neonicotinoid insecticides such as imidacloprid and thiamethoxam at early growth stages can help control BPH population.
3. Biological control: Some natural enemies such as spiders, dragonflies, and parasitic wasps help control BPH population. Introducing predators like spiders, damselflies, and ants can help control the population of BPH to some extent.
4. Seedling treatment: Treating seedlings with imidacloprid, thiamethoxam, or fipronil before transplanting can help control BPH population in the early stages of growth.
5. Monitoring: Regular monitoring of the field for the presence of BPH is important. Trap crops and yellow sticky traps can be used to attract and catch BPH. Scouting fields and checking for the presence of insects is important for early detection and control.
In conclusion, it is important to follow a multidimensional approach to control BPH infestation in paddy. Cultural practices such as field sanitation and planting resistant varieties are necessary for long-term control. Insecticides, biological control, and seedling treatment can be used alongside cultural practices for better control of BPH population. Regular monitoring of fields is essential for early detection and effective control of BPH.
