Weeding composition containing cloransulam methyl and imazamox

Abstract

The invention belongs to the technical field of pesticides, and particularly discloses a weeding composition containing cloransulam methyl and imazamox. The weeding composition containing cloransulam methyl and imazamox comprises effective constituents including cloransulam methyl and imazamox, wherein the weight ratio of the cloransulam methyl to imazamox is 4:(0.2-20). The weeding composition containing cloransulam methyl and imazamox has the beneficial effects that grassy weeds and broad-leaf weeds can be removed, the problem that the herbicide controlling spectrum of the cloransulam methyl and imazamox single dosage is narrow in soybean fields is solved, the weeding effect can be effectively improved, the herbicide controlling spectrum is enlarged, the drug resistance of weeds is lowered, the cost and pesticide amount are reduced, and the environmental pollution is reduced. The weeding composition is mainly applied to preventing and treating weeds in soybean fields.

Description

(1) Technical field [0001] The invention relates to the technical field of pesticides, in particular to a herbicidal composition containing clofensulfame and imazethapyr. (2) Background technology [0002] Clossulam is a systemic conductive herbicide, which can be absorbed by weed roots and stems and leaves, and can be transmitted upward and downward through the xylem and phloem, and finally accumulated in the plant meristem, by inhibiting the acetyl Lactate synthase inhibits the biosynthesis of branched-chain amino acids, leading to the blockage of protein synthesis in weeds, resulting in growth stagnation and death of weeds. The agent has both stem and leaf treatment effects and soil sealing effect. It is an ideal agent for controlling the "three vegetables" (commelina, lettuce, and spinach) in the Northeast, but it is ineffective against grass weeds, and it is effective against many broad-leaved weeds. Leaf weeds are also ineffective, and are only effective for large-see...

Problems solved by technology

However, when it is used alone, the medicinal effect is not significant

[0004] my country's soybean planting area is close to 9.68 million hectares, and the total output is as high as 17 million tons. However, due to the damage of weeds, the production is generally reduced by more than 10% every year, and the severe one reaches 20%, which has caused huge economic losses to the growers.

At present, there are many problems with the existing herbicides in soybean fields: one is that long-lasting herbicides such as chlorimuron-methyl and imazethapyr are widely used in some areas, causing residual phytotoxicity of subsequent crops; the other is that soil treatment agents in chemical herbicides Excessive proportion leads to problems such as poor weed control pertinence, unstable efficacy and serious environmental pollution; thirdly, herbicides such as acetochlor, chlorimuron-methyl, trifluralin and pendimethalin are affected by environmental factors, especially soil factors. The influence of surface cover and surface cover is relatively large. In arid areas and under no-tillage conditions, the efficacy of the herbicides decreases significantly, the waste is serious and the environment is polluted. In addition, the extensive use of these herbicides has caused weeds to develop resistance to them, resulting in weed control. not effectively
