Clever selection: On the one hand, we should pay attention to the selection of highly toxic pesticides such as monocrotophos, methamidophos, phosphonium, insecticidal mites, sedum, carbendazim, carbendazim, thiophanate, triadimefon, Tricyclazole, fluconazole, etc., such pesticides can be quickly transmitted to various parts of the plant after being absorbed by the stems and leaves of the crop, and its efficacy is less affected by rainfall; 1605, methyl 1605, trichlorfon, anti-coordination Pesticides such as quetiapine, chlorfenapyr, fenvalerate, green lactate, and dexamethasone, although not having systemic conduction, have strong penetrating and anti-scouring ability on the surface of the crop, and are therefore suitable for the rainy season. Apply. It has been reported that when applied to crops for 2 hours, Ye Kuling can produce systemic conduction; after application of phosphonamine, it can quickly enter the interior of the plant. About 50% of the dose enters plant tissue 1 hour after application; After half an hour and 1 hour after the tricyclic azole spray, it had no effect on the efficacy. On the other hand, it is necessary to pay attention to the selection of quick-acting pesticides with strong knockdown force, such as Kangwei, Kuweiwei, Weiweiwei, Weiduowei, Guangkewei, Xinweiwei, cotton boll, Wulingling, Xinguang 1 No. and pyrethroid pesticides. After the application of such pesticides, the prevention and control of pests and diseases can be quickly exerted, thereby avoiding or reducing the leaching of the medicament by rainwater. It has been shown that aphids on crops can be killed in a few minutes after application.
Skillful application: The rainy season is often the most common season for various field crops, fruit trees, vegetables and other pests and diseases. When applying pesticides, it is necessary to pay attention to spraying in the rainless period; under normal circumstances, in case of rain within 24 hours after spraying, it is necessary to re-spray once and appropriately reduce the spraying concentration.
Cohesive: Adding an adhesive to the agent to enhance the adhesion of the pesticide on the stems and leaves of the crop, and improve the control effect; soy flour, polyvinyl alcohol, skin glue, etc. are commonly used adhesives.
