Description
technical field [0001] The invention relates to a crop protection agent, and also relates to a method for controlling crop diseases and insect pests. Background technique [0002] Rice sheath blight and rice blast have always been important diseases during the rice growth period, causing serious losses all year round. In recent years, the occurrence of rice smut has been on the rise in Anhui, Hubei, Jiangsu and other rice-growing areas, which has also caused serious yield loss and seriously affected rice quality. The rice leaf roller, the rice stem borer, the rice stem borer, and the rice borer are several kinds of pests that cause serious damage to rice during the growth period. Among them, the rice leaf roller is a migratory pest that is widespread in all rice regions in my country. Occurs, its suddenness is strong, the damage area is wide, it is one of the main pests of rice, and it causes the reduction of rice production all the year round. For a long time, people have ...
