30%醚菌酯SC防治小麦叶锈病、白粉病田间药效试验

防治小麦叶锈病、白粉病的田间试验表明：30％醚菌酯SC对小麦叶锈病、白粉病均有较好的防治效果，是一种高防效、低残留、安全性好的新型广谱性杀菌剂。分别在小麦锈病和小麦白粉病的发病初期，使用剂量225～315ml／hm^2(有效含量，下同)，连续用药2次，对小麦锈病的防效达到85％以上，对白粉病达到90％以上。

Field Experiments on the Efficacy of Kresoxim-methyl 30% SC on Wheat Leaf Rust and Powdery Mildew

Field experiments with wheat leaf rust (caused by Puccinia recondita f. sp. tritici) and wheat powdery mildew (caused by Blumeria graminis) indicated that kresoxim-methyl 30% SC provides relatively good control of these diseases. Kresoxim-methyl is a new, highly effective, broadspectrum fungicide with low residual and good safety. Application at 225 to 315 ml/ha in the early stages of disease development, with two consecutive treatments, provided control of wheat leaf rust and powdery mildew averaging >85 and >90%, respectively. Control efficacy was significantly greater than that provided by common fungicides currently on the market.
