摘要
为明确井冈霉素和噻呋酰胺对玉米纹枯病的防治效果及对产量的影响,于玉米纹枯病发病初期采用喷雾法进行田间药效试验。结果表明,24%井冈霉素水剂商品用药量600、1 200 mL/hm2和240 g/L噻呋酰胺悬浮剂商品用药量150、300、600 mL/hm2处理对玉米纹枯病有较好的防效,防效在77.90%~88.53%,其千粒重显著高于空白对照处理。
To evaluate the control effects and the effects on yield of jinggangmycin and thiofuramide on maize sheath blight,the field trials were carried out by spraying in early stage of maize sheath blight.The results showed that 24%of jinggangmycin AS 600,1200 mL/hm^2 and 240 g/L thifluzamide SC 150,300,and 600 mL/hm^2 all had better control efficacy on corn sheath blight.The control ef⁃fects was 77.90%to 88.53%,and 1000-grain weight was significantly higher than that of the control.
