1998～ 1999年田间试验表明 ,蚜粉克星对大麦纹枯病、白粉病、麦圆蜘蛛及穗蚜具有良好的防治效果 ,一般用 11%蚜粉克星 EC12 0 0～ 150 0 ml/ hm2 对纹枯病的防效比 5%井冈霉素水剂3750 ml/ hm2 略低 ;对白粉病的防效与粉锈宁相当 ;对麦圆蜘蛛和穗蚜的防效与 4 0 %氧化乐果112 5ml/ hm2 相当 ,蚜粉克星具有持效期长及一药多治的特点。 3月 5日前后用药 ,防治大麦纹枯病兼治麦圆蜘蛛 ;4月 18日前后用药 ,防治大麦白粉病兼治穗蚜。用量以 12 0 0～ 150 0 ml/ hm2 为宜。
Field experiments from 1998 to 1999 showed that the prophase powdery mildew had good control effects on the sheath blight of barley, powdery mildew, spider mite and spike aphid, and was generally treated with 11% aphid powder nectar EC12 0-150 0 ml / hm2 The control effect of blight was 5% lower than that of Jinggangmycin 3750 ml / hm2. The control effect on powdery mildew was comparable to that of triadimefon; hm2 quite, aphid powder nemesis has a long duration and a multi-drug treatment characteristics. March 5 before and after treatment, prevention and treatment of barley sheath blight and cure wheat round spider; April 18 before and after treatment, prevention and cure of barley powdery mildew cure ear aphid. Amount of 12 0 0 ~ 150 0 ml / hm2 is appropriate.
