1. It is prohibited to use highly toxic and high-residue pesticides such as 1605, 1059, methamidophos, organic amalgam, arsenic, chlordane, cyanide, dibromochloropropane, and chloroacetic acid amine.

2, the right medicine and timely medication: a lot of pests and diseases of vegetables, and sometimes several pests and diseases occur at the same time, there must be targeted use of pesticides and methods of application.

3. Correctly grasp the use concentration of various types of pesticides: At present, there are many kinds of pesticides and dosage forms. For pesticides with the same name and different dosage forms, the concentration, application method, and time are often different, so it is necessary to strictly follow the types of pesticides. Recommended doses and methods to use.
