当前,麦田化除以低用量,高效的碘酰脲类除草剂为主,如甲绿隆、绿黄隆,但这类药剂也存在着对后茬作物(如棉花、大豆)的药害问题。试验表明,苯黄隆、乙草胺混用可有效的防除麦田杂草,且对后茬作物安全无害。结果显示,苯黄隆+乙草胺对麦田禾本科杂草,阔叶杂草的防效及综合防效分别达79.5％、70.9％、71.2％,对禾本科 At present, the cropping is divided by the low dosage and high efficiency iodine urea herbicides, such as Aconitine and Chlorothalonil, but such medicaments also have the problem of phytotoxicity to the following crops (such as cotton and soybean) . Experiments show that the mixture of benzene Huanglong, acetochlor can effectively control weeds in wheat fields, and the safety of the crop is safe. The results showed that the control effect and the control efficacy of the combination of metronidazole + acetochlor on cereal weeds and broad-leaved weeds were 79.5%, 70.9% and 71.2%, respectively.
