As people pay more attention to health, everyone likes to use pollution-free methods to control pests and diseases during planting, and rice is no exception. This article will introduce how rice diseases can be controlled without pollution.
1. Select resistant varieties
In combination with the occurrence of local weather pests and diseases, select suitable resistant varieties.
2, salvage sclerotia
According to the sclerotia formed in the later stage of the disease, it will fall into the rice field and become the pathogen of the next year. When cultivating the field, salvage the sclerotia and burn it, which is of great significance for the prevention and treatment of sheath blight.
3, physical, biological and other prevention and control technology
Light trapping physical control technology; sexual attractant trapping; rice and duck co-invigorating pest control and weed control; use a series of high-efficiency biological pesticides to control various pest and disease technologies.
4, rice field super-granting drugs to prevent tillering pests and diseases technology
Two to three days before the transplanting of the seedlings, multiple doses of pesticides such as aphids, rice blast, rice locusts and rice planthoppers were sprayed to prevent or mitigate the occurrence of pests in the field.
5, mixed spikes in the early stage of heading
In the early stage of rice blasting, the pesticides for preventing rice blast are mixed with the pesticides for controlling sheath blight and rice planthopper, and the purpose of preventing multiple pests and diseases is achieved by one application.
6. Rice field cultivation and treatment technology
During the peak period of wintering and phlegm of locusts, the winter leisure fields and green fertilizer fields were cultivated in time, and the water immersion was deepened, so that the mites could not be properly feathered and the base number was reduced.
7. Reduce the amount of drug use and control technology
Using 40% chlorantraniliprole and thiazide (fogo) wettable powder to control stem borer and rice leaf roller, using 30% difenoconazole and propiconazole (Ai Mi) emulsifiable concentrate to control disease.
