摘要
2009年田间小区试验结果表明:在小麦扬花初期施用42%咪鲜·甲硫灵WP 60-80 g/667m2一次,对小麦赤霉病的病穗率防效达87.12%～91.13%,病指防效达90.18%～95.46%,均显著高于50%多茵灵WP的防效.2010年大田示范结果显示:于抽穗扬花盛期施用42%咪鲜·甲硫灵WP 60 g/667m2一次,对小麦赤霉病的病穗防效和病指防效分别为71.69%和78.45%.显著优于常规药剂40%多·酮·福美双WP的防效,也高于50%多茵灵WP的防效,且对小麦生长发育安全.
The result of field plot trials in 2009 showed that when 42% Prochloraz·Thiophanate-Methyl WP at the dosage of 60~80 g/667m2 was applied once at the beginning stage of wheat flowering,the control effects against the infected spikes and disease index caused by wheat gibberellic disease were 87.12%~91.13% and 90.18%~95.46% respectively,which were significantly higher than those of 50% Carbendazim WP.Especially,in 2010(the outbreak year of wheat gibberellic disease),the field demonstrations indicated that the control effects on the infected spikes and disease index caused by wheat gibberellic disease were 71.69% and 78.45% respectively when 42% Prochloraz·Thiophanate-Methyl WP at the dosage of 60 g/667m2 was applied once at the flourishing stage of heading and flowering of wheat,and its control effect was significantly better than that of 40% Carbendazim·Triadimefon·Thiram WP and 50% Carbendazim WP.42% Prochloraz·Thiophanate-Methyl WP was safe to the growth and development of wheat.
