With the increasing variety of pesticides, farmers' awareness of pesticides is now more and more important, and it is very important to strengthen the knowledge of safe drug use by farmers. If some pesticides are afraid of rain, then if you encounter the rainy season, how can you better choose pesticides to use?
Systemic pesticides, such as omethoate, sputum and other insecticides , and bactericides such as carbendazim and thiophanate, which can absorb more than 60% of the active ingredients in crops after 4-6 hours, 6 hours. Even after heavy rain, it can still play a role in insecticide and sterilization.
