In fact, at present, there are not many pesticides with powerful "waterproof" functions. When it is raining, try not to spray pesticides until after the rain. If it is really necessary to spray pesticides, you can avoid the loss of efficacy caused by rain by selecting systemic, quick-acting, rain-tolerant and microbial pesticides.
Systemic pesticide
Systemic pesticides can enter the plant through the roots, stems, leaves and other parts of the crop, and transport to other parts, which will work in a short period of time. For example, bactericidal insecticides such as carbendazim, triadimefon, and leaf blight have 80% of the active ingredients absorbed into the tissues by the crops 4 to 5 hours after application, and less to lose their medicinal properties due to rainwater leaching.
Fast-acting pesticide
Such as insecticides, dichlorvos, chlorpyrifos, monocrotophos, chlorpyrifos, enemy killing, chlorpyrifos, chlorpyrifos, anti-carbocarb, pyrethroids and other pesticides, with strong contact and toxicity The killing effect is as short as 1 to 2 hours after application, and the pest can be killed by 4 to 5 hours, which is less affected by the rainy season.
Washable pesticide
Among the fungicides, Jinggangmycin, Herbicide, Tricyclazole, and Scopolamine have good rain resistance. Even after showering for 1 to 5 hours, they will not be washed and affect the efficacy.
Microbial active pesticide
The commonly used microbial pesticides such as Jinggangmycin, Chunleimycin and Beauveria bassiana are more conducive to the germination and reproduction of sporophytes under high humidity conditions. The application of such pesticides in rainy days can fully exert their bactericidal and insecticidal effects.
