作保灵对长残效除草剂的解毒效应

Detoxification of TNA to Long Residual Herbicide

利用田间试验方法研究保护剂长残效除草剂解毒效应。不同保护剂对豆磺隆解毒效应有差异 ,作保灵解毒效应最明显 ,但在除草剂高残留量时解毒作用下降。作保灵对三种长残效除草剂都具有明显的解毒作用 ,作物的出苗率可恢复 80 %～ 10 0 %。解毒效应顺序为油菜 >白菜 >

This paper presented the research on detoxification with antidote to long residual herbicides in greenhouse and field test. There were different antidotal effective with different antidote to long residual herbicides. Long residual herbicide was conspicuous detoxification by TNA with soak seed sensitive crop, but when residual rate of herbicide was high, antidotal effective of TNA was decreased. Residual damaging of chlorsulfuron, chlorimuron-ethyl and imazethapyr to sensitive crop were antidotal with TNA. Consequent succession of antidotal effective to sensitive crop were: corn >rapeseed>Chinese cabbage>sugarbeet.
