白叶枯病是水稻的主要病害之一,我县近几年来发生面积不断扩大,危害逐年加重。1983年全县二晚发病面积1.67万亩,1984年上升到2.35万亩。大田药剂防治一直沿用在禾苗出现明显症状时,病情达到一定程度后才施药,要反复用药多次才能见效。为探讨省工、省成本,又能达到理想的防治效果的施药方法,1984～1985年分别在鲁溪乡梅岩村和浬溪乡上清村,进行了药剂处理病田土壤表面和浸秧防治白叶枯病的试验。并结合试验进行了大面积的示范,现将结果简介如下: 一、试验情况
Bacterial leaf blight is one of the main diseases of rice. The area of our county has been expanding continuously in recent years, and its harm has been increasing year by year. In 1983 the county two night incidence area of 16,700 mu, 1984 rose to 23,500 mu.
