通过在沿江地区的防治试验示范,总结出较为完整的水稻纹枯病药剂防治技术:纹枯病防治指标为病株率1%,未达防治指标时开始用药控制效果较好,可减少后期的防治压力。在田间病情重发的情况下,要选择高效药剂进行控制,如75%肟菌.戊唑醇WG 10 g/667m2或12%井冈.戊唑醇SC 100 mL/667m2、30%苯甲.丙环唑EC 20 mL/667m2等。在整个水稻生育期防治纹枯病不得少于4次用药,并且要选择防效较好的药剂交替使用。
Through the demonstration of prevention and cure in the Yangtze River area, a more complete prevention and control technology for rice sheath blight was concluded: the control index of sheath blight was 1% of the diseased plants, the control effect was better when the control index was lower than the control index, Preventing stress. In the case of recurrent disease in the field, the choice of efficient agents to control, such as 75% oxime bacteria. Tebuconazole WG 10 g / 667m2 or 12% Jing Gang. Tebuconazole SC 100 mL / 667m2, 30% Cycloconazole EC 20 mL / 667m2 and the like. During the growth period of rice sheath blight prevention and treatment shall not be less than 4 times, and to choose the better control effect of the alternate use.
