1. Adding wine: Any pesticide will add 50 grams of white wine per unit of acre, and its insecticidal effect will be significantly improved. For example, 40 ml of methamphetamine plus white wine 50-100 g per acre, 50 kg of water, the control effect of rice planthopper can reach 94%; with the use of dichlorvos, can increase the control effect by 20%.
2, adding fertilizer: 75 grams of 40% dimethoate emulsifiable concentrate per acre, plus 500 grams of urea, 50 kg of water, better insect control effect, and can promote crop yield increase. Adding 0.1% concentration of 50% dichlorvos emulsifiable concentrate to 1% urea solution, the anti-mite effect is over 98%, and the control effect against red spider is 92~96%.
3, plus neutral detergent: adding neutral detergent in the liquid, can improve the control effect by 25%. For example, in 50 kg of 50% dichlorvos 1000 times liquid, adding 50 grams of washing powder can enhance the overall adhesion, and the effect of controlling rice planthopper is over 95%.
4, refueling: when using pesticides mixed with poisonous soil to spread insects, add 1 kg of waste engine oil or diesel oil per mu of toxic soil and mix and apply, which can improve insecticidal power.
5, compound mixed use: such as marathon plus rice bran, dimethoate plus rice bran, can improve the control of rice planthoppers, and treat other pests and diseases.
