It is well known that the rational mixing of pesticides can play a role in treating multiple diseases and insects, saving labor and time, and delaying the resistance of pests and diseases. However, unreasonable use can also lead to decreased efficacy and food safety.
The long-term use of a single variety of pesticides, especially some pyrethroid insecticides and systemic fungicides, is likely to cause resistance to pests. However, the rotation of pesticides of different natures must ensure that chemical reactions are not maintained and the physical properties remain unchanged. Pesticide mixing is generally done with a sufficient amount of water to prepare a single dose of the drug solution, and then use this solution to dilute another single agent, and can not mix the two single agents first, and then diluted with water to avoid adverse reactions.
