The following methods are feasible. 1. Rotate medication. Use pesticides with different mechanisms as much as possible and rotate them. For example, organic phosphorous preparations, pyrethroids, organic nitrogen preparations, and the like of insecticides are used interchangeably. In bactericides, ingested bactericides generally cause drug resistance, such as carbendazim, thiophanate-methyl, aluminum-phosphorus-aluminum, and the like. However, contact bactericides, such as zesin, dexammonium, Bordeaux, sulphur, and sterilizers, are not likely to cause drug resistance, and are better alternatives for rotation. 2. Mix medication. That is, the use of two agents with different modes of action and different mechanisms can slow down the occurrence of drug resistance. For example, if carbendazim is used together with sterilized Dan, thiophanate-methyl is used together with acetaminophen, and organic phosphorus is mixed with pyrethrin. Note: Mixed pesticides must also be used interchangeably. 3. Pesticides are intermittently used or deactivated. When pests become resistant to a certain pesticide, if the drug is stopped in the short term, the phenomenon of drug resistance may gradually decline or even disappear. 4. Use the correct application technique. The uniform distribution of pesticides on crops can slow the growth of drug resistance. Such as the use of ultra-low volume spray method, ultra-low smoke method, ultra-low spray method and dusting method.
