Four strokes for summer use pesticides can learn

1. Use quick-acting, systemic pesticides. Such as fast extinguishes kills, eliminates sweep profit, quick gram, metalaxyl, monocrotophos, methomyl and so on, this kind of pesticide action is strong, knocks down quickly, after 4 to 5 hours, has 80% active ingredient Absorbed by crops, insects and germs can be killed even if it rains.

2. Add the adhesive in the liquid agent and the 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 on crops and insect pests and increase the use of pesticides.

3. Dilute pesticides with clean 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 a lot of impurities, in addition to the preparation of pesticides easy to plug the nozzle, but also destroy the suspension of pesticides and reduce pesticide activity.

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