White Backed Plant Hopper (W.P.H.) and Brown Plant Hopper (B.P.H.) are two major pests that affect paddy (Jhona) crop, especially in the South-east Asian countries. Both of these pests suck the sap from the plants, leading to reduced yield and stunted growth. Therefore, it is essential to have proper information regarding their control.
Here are some important tips for controlling W.P.H. and B.P.H. in paddy crop:
1) Early detection: It is crucial to detect these pests at the early stage of infestation. Visual observation of yellowish spots on leaves, stunted growth, and sticky honeydew excretion are some of the symptoms of pest infestation.
2) Crop management practices: Proper crop management practices such as intermediate flooding, use of resistant varieties, crop rotation, and planting during the right season can help in controlling these pests.
3) Chemical control: Insecticides like Imidacloprid, Androcil, and Thiomethaxam are effective in controlling W.P.H. and B.P.H. However, it is important to follow the recommended dosage and application methods to avoid resistance development.
4) Biological control: The use of natural enemies like Dragonflies, Gryllus, and Spiders can significantly reduce the population of these pests. The use of neem extract and Beauveria bassiana fungus can also help in biological control.
5) Regular monitoring: Regular monitoring of the crop for the presence of pests, especially during the flowering and maturity stage, can help in taking timely control measures.
In conclusion, the effective control of White Backed Plant Hopper and Brown Plant Hopper in paddy crops requires the implementation of integrated pest management strategies that combine chemical, biological, and cultural practices. With proper monitoring and application of control measures at the right time, it is possible to minimize the damage caused by these harmful pests and ensure successful paddy cultivation.
