Chemical control When the initial stage of the field is controlled, the following insecticides can be used, which are 240g/L spirotetraethyl ester suspending agent 4000-5000 times liquid and 10% imidacloprid wettable powder 1500 times liquid. The specific operation method is uniform spraying with water. Over the generations, continuous control, the specific number of use depends on the insect situation, if severe, can be mixed with 2.5% bifenthrin EC and 25% thiamethoxam wettable powder, 22% dichlorvos can be used in the protection zone 0.5kg of mu with a knapsack mobile smoker to apply smoke agent, the effect is also very good.
