摘要
进行了72%噻吩磺隆.异丙隆可湿性粉剂对麦田猪秧秧和看麦娘的防效评价试验。结果表明：以1500-1800 g/hm^2剂量施药后20 d对猪秧秧平均株防效77.3%-87.5%,对看麦娘平均株防效75.1%-85.5%。施药后40 d对猪秧秧平均鲜重防效80.2%-90.3%,对看麦娘平均鲜重防效78.3%-88.5%。而单用噻吩磺隆对看麦娘株防效和鲜重防效仅70%左右,单用异丙隆对猪秧秧株防效和鲜重防效在40%以下。
The effect evaluation of 72% thifensulfuon isproturon wettable powder on catchweed and Alopecuras aequalis in wheat field was conducted. The results showed that the control effect of 72% thifensulfuon isproturon with the dose 1 500 to 1 800 g/hm^2 to catchweed plant and A. aequalis plant was 77.3% to 87.5% and 75.1% to 85.5% after sprayed 20 days. The control effect of 72% thifensulfuon isproturon with the dose 1 500 to 1 800 g/hm2 to the average fresh weight of catchweed and A. aequalis was 80. 2% to 90. 3% and 781 3% to 88. 5% after sprayed 40 days. When thifensulfuon or isproturon was singly used, the plant and fresh weight control effects were about 70% on A. aequalis and under 40% on catchweed, respectively.
