In control strategy, strictly securing the four passes is the key. 1. The pass of salvaging sclerotia - sheath blight mainly overwinters in rice fields in the form of sclerotia, and overwintering sclerotia generally have 60%-70% able to germinate from winter and spring through to early rice transplanting. The vast majority of sclerotia are lighter than water and can float with the water for a long time. After the rice field is irrigated,
