Brown planthoppers such as brown planthoppers and planthoppers are the main pests of rice in the later period, and often cause yellowing of rice leaves and growth of blackheads. The favorable weather conditions since the beginning of autumn this year are conducive to the occurrence and harm of rice planthoppers. Although the current insect population is lower than the number of replants occurring in previous years, there are large differences among the fields, and the number of burrowing insects in a few fields is as high as 5,000 or more. There are also a large number of short-winged adults and eggs in the fields. With the arrival of rice planthoppers at the peak of egg hatching around September 20, field insect populations will rise rapidly, posing a threat to rice growth. Attention must be paid to the production, and the last stage of rice ear-bite prevention and control must be firmly established. Fields with poor early control and high pests in the field are the focus of current prevention and treatment. It is possible to use 25% pymetrozine suspension 20 ml and 25% buprofezin WP 60 g/mu, add 50 kg of water spray, and apply pesticides. After the water for 3 days. Pay attention to increase the amount of water in order to ensure control efficiency. Efficient and low-toxicity pesticides are required to be used, and organophosphorus pesticides such as chlorpyrifos, triazophos, acephate, etc. are not used arbitrarily.
