摘要
为了筛选出防治甘草锈病的有效药剂,试验选用4种杀菌剂并分别设不同剂量,通过1次施药及药后7d两次施药对甘草锈病进行防治。结果表明:1次药后7d,10%苯醚甲环唑WG的防效较高,180、90ga.i./hm2剂量下的防效均在60%以上,表明该药剂对甘草锈病具有较好的速效性;2次药后7d,各药剂不同剂量对甘草锈病的防效均有所升高,其中10%苯醚甲环唑WG的防效最高,180、90、60ga.i./hm2的防效分别为74.46%、76.38%和68.74%,25%丙环唑EC和20%三唑酮EC的防效相当,70%丙森锌WP的防效最低;2次药后14d,10%苯醚甲环唑WG仍保持较高防效,180、90、60ga.i./hm2剂量下的防效分别为72.33%、65.16%和66.15%,表明该药剂对甘草锈病具有较好的持药性。10%苯醚甲环唑WG对甘草锈病具有较好的防治效果。
