田间试验结果表明,在水稻生长中期,20%井冈.咪鲜胺可湿性粉剂40~50 g/667m2对水稻纹枯病的防治效果达79.64%~83.12%,显著好于对照药剂20%井冈霉素可溶性粉剂40 g/667m2的防治效果,药液量为50 kg粗喷雾;在水稻生长后期,20%井冈.咪鲜胺可湿性粉剂30~40 g/667m2对稻曲病的控制效果为77.23%~87.13%,优于或极显著好于对照药剂20%井冈霉素可溶性粉剂50 g/667m2的防治效果,可同时控制纹枯病的危害,达到一喷二防、一药多效的目的,且对水稻生长发育没有不良影响,在无公害水稻生产中具有广阔的应用前景。
The results of field experiments showed that the control effect of 40% ~ 50 g / 667m2 20% Jinggang prochloraz WP was 79.64% ~ 83.12% on rice sheath blight in the middle stage of rice growth, which was significantly better than that of 20% The control effect of 20% Jinggangmycin and prochloraz WP 30 ~ 40 g / 667m2 on rice false smut was 77.23% at the late stage of rice growth, % ~ 87.13%, better than or very significantly better than the control agent 20% Jinggangmycin soluble powder 50 g / 667m2 control effect, which can simultaneously control the sheath blight of the harm to achieve a spray two anti-multi-drug purposes , And has no adverse effect on the growth and development of rice and has broad application prospects in the production of pollution-free rice.
