Abstract
The invention relates to a synergistic herbicide composition and an application method thereof and in particular relates to a synergistic herbicide composition which is prepared through ternary combination of mesotrione, butachlor and flupoxam and is applied to corn fields. The synergistic herbicide composition comprises (a) 2-(2'-nitro-4'-methanesulfonylbenzoyl)-1,3-cyclohexanedione, (b) 2-chloro-N-(2,6-diethylphenyl)-N-(butoxymethyl)acetamide and (c) 1-[4-chloro-A-(2,2,3,3,3-pentafluoropropyl)m-methyl]-3-carbamoyl-5-phenyl-1H-1,2,4-triazole, wherein the weight ratio of (a) to (b) to (c) is (1-50):(1-50):(1-50). The synergistic herbicide composition has a beneficial effect on controlling weeds in the corn fields, effectively controls annual grassy and broadleaf weeds in the corn fields, effectively controls generation of weeds with resistance, and simultaneously can reduce the overall use cost and expand the weed control spectrum.
Description
[0001] technical field [0002] The present invention relates to a synergistic herbicidal composition and its application method, in particular to a synergistic herbicidal combination of three components of mesotrione, butachlor and flufenoxazole, which are applied in corn fields things. Background technique [0003] Corn is one of the most widely distributed food crops in the world, and its planting area ranks third after wheat and rice. China's annual corn production ranks second in the world. The sown area of corn fields accounts for about 1 / 3 of the sown area of dry fields, and the output of corn accounts for about 1 / 4 of the total output of grain crops. In 2011, the national corn output exceeded 200 million tons. [0004] The geographical distribution of corn is extremely wide, and the hazards of weed species are also very complex. Weeds compete with corn for water, nutrients, light and space, affecting the normal growth of corn seedlings, and even causing serio...
