Sure, here’s an article on how to control sucking pests (GPH or BPH) in paddy crop:
Sucking pests like the Green Leaf Hopper (GPH) and the Brown Plant Hopper (BPH) are a major concern for farmers who grow paddy crops. These pests suck the sap from the rice plant, causing it to wilt and eventually die. They also transmit viruses that can further damage the crop. Therefore, it is important to control these pests to ensure a good harvest.
Here are some methods that can help control GPH and BPH infestations in paddy crops:
1. Regular monitoring: It is important to regularly inspect the paddy crop for any signs of GPH or BPH infestation. This will help detect the problem early and prevent it from spreading. Look for yellowing or wilting of the rice leaves, as well as the presence of the pests themselves on the leaves or stem.
2. Biological control: Encouraging natural enemies like spiders, ladybugs, and parasitic wasps can help control GPH and BPH populations. These predators feed on the pests, reducing their numbers. Additionally, planting a diversity of crops like beans or legumes alongside paddy can also provide habitat for these natural enemies.
3. Cultural control: Planting tolerant or resistant varieties of rice can help reduce the impact of GPH and BPH infestations. Some rice varieties have been bred to be resistant to these pests, and planting these can reduce the need for pesticides. Additionally, an appropriate crop rotation schedule can also help reduce pest populations.
4. Chemical control: Pesticides can be used to control GPH and BPH populations, but this should be considered a last resort. Pesticides can be harmful to the environment and can also harm natural enemies that are beneficial to the overall health of the crop. When using pesticides, follow label instructions carefully and use only the recommended amounts.
In conclusion, controlling GPH and BPH populations in paddy crops requires a holistic approach that incorporates regular monitoring, biological and cultural control methods, and the careful use of pesticides if necessary. By using these methods, farmers can ensure that their paddy crops remain healthy and productive.
