The prevention and control indicators of 100 young nymphs and more than 1,000 nymphs.
Prevention techniques include paddy field blocks, prevention and control of newly hatched nymphs, 25% mu ciprofloxacin 80 g + 40% chlorpyrifos 100 ml (or 48% larvae 80 ml); prevention of middle-aged and senior nymphs, mu 40% chlorpyrifos 120 ml ( Or 48% Music 100ml) + Silk Run 15~20g. When applying pesticides, the amount of water should be sufficient, the water consumption of late-maturing single-season japonica rice should be no less than 60 kg for manual sprayers and not less than 30 kg for motorized sprayers; the water consumption per mu for single-season japonica rice and the manual sprayers should not be less than 40 kg. No less than 15 kilograms of motorized sprayers are sprayed on the middle and lower parts of rice, and the field is kept in shallow water for 3 to 5 days after field application.
Anhydrous plots, with 80% dichlorvos (300ml) and dry wet sand (earth) 15-20kg, are distributed from 12 noon to 14 o'clock in the sunny day.
