摘要
以扬麦16为试材,研究了50%咪鲜胺锰盐可湿性粉剂和42%咪鲜.甲硫灵可湿性粉剂对小麦赤霉病的田间防治效果。结果表明:在小麦扬花期,施用50%咪鲜胺锰盐可湿性粉剂900 g/hm2对小麦赤霉病的防治效果最好,病穗防效达76.2%,病指防效达81.0%;施用42%咪鲜.甲硫灵可湿性粉剂1 200 g/hm2对小麦赤霉病也具有较好的防治效果,病穗防效达75.8%,病指防效达79.3%。这2种药剂的防效显著优于对照药剂25%赤霉清可湿性粉剂1 500 g/hm2的防效。
The effects of three bactericides on controlling wheat scab were studied. The results showed that the effect of 900g/hm^2 50% prochloraz-manganese chloride complex WP was the best with the efficiency of 81.0%. The effect of 1200g/hm^2 42% prochloraz · thiophanate-methyl WP was better with the efficiency of 79.3%.
