稻瘟病是危害水稻生产的重要病害,尤其是1984和1985年全省大范围病害流行给我省粮食生产造成的惨重损失仍记忆犹新。多年实践证明,药剂防治是稻瘟病综合防治的一项有效措施,特别是在品种抗性丧失,病害流行的情况下尤为重要。过去防治稻叶瘟习惯用喷雾的方法,由于秧苗生长茂密,即便施用高效药剂也不能有效地控制本田叶瘟危害,本田往往需再施药1—2次来防治叶瘟,给稻瘟病防治带来一定困难。为了改变叶瘟防治的被动局面,争取防治主动权,

In particular, the heavy losses caused by the epidemic of large-scale diseases in our province in 1984 and 1985 have still fresh memories of the grain production in our province. Years of practice have proved that the prevention and control of pesticides is an effective measure for the comprehensive prevention and control of rice blast, especially in the case of loss of variety resistance and prevalence of diseases. In the past, the traditional method of preventing and controlling rice leaf blast was mainly due to the dense growth of the seedling. Even if the high-efficiency medicament was used, it was not able to effectively control the damage of Honda leaf plague. Honda often needed 1-2 times to control the leaf blast, To some difficulty. In order to change the passive situation of leaf plague prevention and control and strive for the prevention and control of the initiative,
