The selection of pest-resistant varieties is the most economical and safe method for controlling pests and diseases; strengthening management after sowing, creating environmental conditions suitable for crop growth and not conducive to the occurrence of pests and diseases can effectively reduce the occurrence of pests.
2. Specify the scope of use of pesticides. According to the chemical nature and toxicity of pesticides, it is forbidden to use highly toxic, highly toxic and long-lasting pesticides on some crops. For example, phoxim used to control fruit tree pests must be used 30 days before fruit harvest.
