According to the pesticide network , when the leaves are applied to the crop for 2 hours, they can produce systemic conduction; after the application of the phosphonamine, they can quickly enter the interior of the plant. About 50% of the dose enters the plant tissue 1 hour after application; Half an hour after the copper spray and 1 hour after the tricyclic azole spray, there was no effect on the efficacy.
Pay attention to the quick-acting pesticides with strong knockdown force, such as phoxim, dichlorvos, omethoate, anti-èšœå¨, 速å¨, mixed weiwei, ç多å¨, Guangkewei, Xinweiwei, cotton boll, and extinguish Lingling, Xinguang No. 1 and pyrethroid pesticides.
