目前,化学防除麦田禾本科杂草看麦娘和阔叶杂草主要使用国产绿麦隆、绿黄隆和进口骠马、巨星、使它隆等除草剂。绿麦隆、绿黄隆用量大,且药效不够稳定。骠马只杀看麦娘,对阔叶杂草无效;巨星和使它隆只杀阔叶杂草,对看麦娘无效。如使用骠马+巨星或使它隆防除禾本科杂草和阔叶杂草,每亩需成本10元以上。为了寻找国产杀草谱广、成本低的替代除草剂,我们于1989～1990
At present, the chemical control of wheat grass weeds and broad-leaved weed motherland broadleaf weeds are mainly used domestic chlorotoluron, chlor-lon Huang and import plutonium, superstar, making it Long and other herbicides. Chlorotoluron, Luhuanglong dosage, and efficacy is not stable enough.骠 horses only kill Aima, the broad-leaved weeds invalid; superstar and make it only kill broad-leaved weeds, to see Maisen ineffective.
