Herbicide combination and use thereof
2009
The invention relates to a herbicide composition, which comprises the following active compositions: sulfonylurea or sulfonylurea salts, clopyralid or clopyralid salts, and quinclorac or quinclorac salts or quinclorac ester, wherein the weight ratio of the sulfonylurea or the sulfonylurea salts to the clopyralid or the clopyralid salts to the quinclorac or the quinclorac salts or the quinclorac ester is 0.1-5:0.1-10:0.1-10. Compared with a single herbicide, the herbicide composition obviously improves the weed control effect, reduces the dosage, reduces the cost of pesticides and simultaneously reduces the influence of the pesticides on the environment and widens the weed control spectrum, and has good controlling effect on Gramineae and broad leaved weed of paddy fields.
