摘要
为明确麦草畏、苯磺隆、滴·氨氯等不同作用机理的除草剂对恶性杂草刺儿菜的防除效果。采用田间小区试验、茎叶喷雾法测定了18种除草剂对刺儿菜的田间防效。结果表明:施药后30天,26%滴·氨氯水剂和48%麦草畏水剂对刺儿菜的株数和鲜重防效最高,分别为71.19%、70.69%和91.63%、88.67%;其次为10%乙羧氟草醚乳油和41%草甘膦水剂,株数防效分别为64.88%和63.15%,鲜重防效均为84.69%。其余药剂对刺儿菜的株数和鲜重防效差,防效在60%以下。20%百草枯水剂、25%辛酰溴苯氰乳油和24%乳氟禾草灵乳油处理区药后15天防除刺儿菜效果较好,但药后30天刺儿菜复生现象明显,防除效果明显降低。
Field efficacy trail was conducted to define the control effect on Cirsium setosum by 18 herbicides of different mechanism of action such as dicamba, tribenuron-methyl, 2,4-D butylate.picloram and so on. The results showed that, the amount and weight control effects of 26% 2,4-D butylate.picloram and 48% dicamba were 71.19%, 70.69% and 91.63%, 88.67% respectively and higher than other herbicides on the thirty day after treatment. The control effect of 10% fluoroglycofen-ethyl and 41% glyphosate were followed, and the amount control effects were 64.88% and 63.15% respectively, and the weight control effects were both 84.69%. The control effect of other herbicides was lower than 60%. Resuscitation rate of Cirsium setosum in paraquat, bromoxynil octanoate and lactofen treatment areas were higher than others, and control effect was reduced on the 30 days after treatment.
