[目的]明确16%井冈·噻呋SC对铁皮石斛白绢病的防治效果及使用剂量。[方法]采用对整个植株喷雾法检测防治效果,以邓肯新复极差法检验差异显著性。[结果]16%井冈·噻呋SC 80~160 mg a.i./kg剂量处理,药后14 d,防效85.33%以上,高于对照药剂4%井冈霉素水剂80 mg a.i./kg的防效78.36%,与对照药剂240 g/L噻呋酰胺悬浮剂120 mg a.i./kg的防效90.60%相当。[结论]16%井冈·噻呋SC以80~160 mg a.i./kg剂量处理,能有效控制铁皮石斛白绢病的为害,可以在生产上推广使用。
[Objective] The research aimed to determine the control effect and dosage of 16% Jinggangtufen SC on Dendrobium candidum Sclerotium. [Method] The whole plant was sprayed to test its control effect. The difference between the two groups was tested by Duncan new repolarization test. [Result] The control effect was 16% Jinggangthuofu SC 80 ~ 160 mg ai / kg, and the control effect was 85.33% on the 14th day after drug treatment, which was higher than that of the control drug 4% Jinggangmycin 80 mg ai / kg 78.36%, which is equivalent to 90.60% of the control efficacy of 240 g / L thifluzamide suspension 120 mg ai / kg. [Conclusion] The treatment of 16% Jinggangthufen SC with 80 ~ 160 mg a.i./kg dose could effectively control the damage of Dendrobium candidum Sclerotium, which could be promoted in production.
