Problems solved by technology

However, most of the cornfields in my country have suffered from weeds to varying degrees over the years. The main weeds that harm the cornfields are crabgrass, barnyardgrass, foxtail, goosegrass, retroverted amaranth, and purslane. There are many types of grasses, wide distribution, vigorous growth, and a single plant covers a

Abstract

The invention discloses a ternary weed-killing composition for a corn field. The ternary weed-killing composition is characterized in that halosulfuron methyl, bentazone and atrazine are adopted as effective components, and the weight rate of the halosulfuron methyl, the bentazone and the atrazine is (10-20):(1-5):(3-15). The ternary weed-killing composition has the characteristic of wide weed killing spectrum, and also has the advantages that a higher synergistic effect can be generated, the control effect of the composition is obviously improved compared with that of a single agent, the use dosage of the pesticide is reduced, the use times of the pesticide are reduced, the production cost is reduced and the influence of the pesticide on the ecological environment is reduced.

Description

[0001] Technical field [0002] The present invention involves a weeding composition, which is specifically a triplet composition for corn fields. Background technique [0003] Corn is one of the main crops in my country and is the second largest crop after rice.However, most of the corn fields in our country have had different degrees of grass harm over the years. The weeds that mainly endangers cornfield include horse Tang, Cycles, dogtails, beef tendon grass, anti -branches, purslane, etc.There are many types of grass, wide distribution, and strong growth. The single plant covers a large area. It competes with corn in large quantities of space and nutrients, which causes the growth of corn to be limited, which directly affects the yield and quality of corn.The fine leaf yellow, etc., seriously affects the quality of corn, which can reduce the production range by 35%.Therefore, domestic corn fields are widely used to avoid cutting herbicides to avoid reducing production due to ...
