1. Use quick-acting and systemic pesticides . Such as the rapid killing of Ding, Deshi Li, Su Keling, metalaxyl, monocrotophos, methomyl, etc., such pesticides strong, knockdown fast, 4 to 5 hours after use, more than 80% of the active ingredients It is absorbed by crops and can kill pests and germs even if it rains.
2. Add an adhesive to the liquid and wettable powder. When formulating pesticides, adding 100-150 g of soy flour or washing powder per 100 kg of liquid can increase the adhesion of pesticides on crops and pests, and improve the use of pesticides.
3. Dilute the pesticide with water or river water. Well water generally contains many minerals, and the diluted pesticides are easy to produce chemical cooperation, forming a precipitate to reduce the efficacy. The sewage contains many impurities. In addition to easily blocking the nozzle, the pesticide will also destroy the suspension of the agent and reduce the vitality of the pesticide.
4. Do not wear chemical fiber clothes to spray. Chemical fiber clothes have strong permeability, poor water absorption, poor anti-staining ability, and are prone to infectious poisoning. Therefore, it is advisable to spray clothes in cotton in the summer, and wear protective gloves such as masks and gloves.
