1. Add an adhesive to the liquid and wettable powder. When formulating pesticides, adding 100 to 150 grams of soy flour or laundry detergent per 100 kilograms of liquid medicine can increase the adhesion of pesticides to crops and insect pests, and improve the use of pesticides.

2. Use quick-acting, systemic pesticides. Such as fast killing, killing, quick-impact, metalaxyl, methomyl, etc., these pesticides have strong effects, and they knock down fast. After 4-5 hours, more than 80% of active ingredients are absorbed by crops. Even if it rains, it can still kill pests and germs.

3. Do not wear chemical fiber clothing spray. Chemical fiber clothing has strong permeability, poor water absorption, poor anti-fouling ability, and prone to infectious poisoning. Therefore, it is advisable to spray cotton in the summer and wear protective clothing such as masks and gloves.

4. Dilute pesticides with fresh water and river water. Well water is generally rich in minerals, dilution of pesticides is easy to produce chemical and synergistic effects, and precipitation is formed to reduce efficacy. Sewage contains more impurities, in addition to the preparation of pesticides easy to plug the nozzle, but also destroy the suspension of pesticides and reduce pesticide activity.
