水稻种子带菌是恶苗病的初侵染源,药剂浸种是防治恶苗病的主要措施。近年来水稻恶苗病有逐年上升的趋势,发病率高,危害较重。播种带菌的种子,在整个生育期均可发病,出苗后可随即死亡,成株期即使能抽出穗也是穗小粒少甚至颗粒无收,对产量影响较大。为此,在两年试验的基础上,从防效、成本等方面进行综合比较,筛选出防治水稻恶苗病的最佳药剂。试验情况如下。 Rice seedling is the primary source of infection of diarrheal disease, soaking the seed is the main measure to prevent and treat the disease. In recent years, the incidence of rice stomatitis has been increasing year by year with high incidence and serious harm. Sowing contaminated seeds throughout the growth period can be disease, emergent immediately after death, even if the plant can be sprouted out less spikelets or even crop failure, a greater impact on the yield. Therefore, on the basis of two years of experiments, a comprehensive comparison was made on the aspects of prevention and control and cost, and the best medicament for preventing and curing rice Bakanae disease was screened out. The test is as follows.
