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/hm2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。
Thifensulfuron-methyl was tested in 72% .Isoproxil WP Tests on the Control Effect of Piggy Seedlings and Wheat in Wheat Field. The results showed that the average control effect on pig seedlings was 77.3% ~ 87.5% at 20 d after application of 1500 ~ 1800 g / hm2, and the average control effect was 75.1% ~ 85.5%. The average fresh weight of piggy seedlings was 80.2% ~ 90.3% at 40 days after spraying and 78.3% ~ 88.5% of the average fresh weight was observed at 40 days after spraying. The use of thifensulfuron alone to see the Amarvus plant control effect and fresh weight control effect is only about 70%, single isoproturon piggy seedling control effect and fresh weight control effect below 40%.
