Abstract
The invention relates to a weeding aqueous solution agent prepared by formulation of paraquat and prowess and a preparation method thereof. The weeding aqueous solution agent consists of the following components by weight percentage: 5-18% of paraquat, 8-25% of prowess, 0.01-0.05% of triazole-pyrimidone, 5-15% of synergist, 8-20% of penetrant and the balance of water. The preparation method comprises the following steps of: stirring paraquat with water by the weight percentage; taking prowess and adding water to stir; taking and adding the penetrant and synergist to a reaction kettle to stir for 10-15 minutes; then adding water to stir for 20-30 minutes; then standing, filtering, filling and sampling for analysis to obtain the finished product. The invention overcomes the defect that the prior weeding agent aims at specific weeds, is an efficient and quick-acting broad-spectrum weeding agent and has a quick effect on annual and perennial weeds and part of broadleaf weeds in wasteland, for example, railways, roads, both sides of river diks, airfields and ridges. The administration cost is 17.4-19.8% lower than that of individually administrated paraquat and prowess and the weeding effect is more obvious than the single agent: paraquat and prowess.
Description
technical field [0001] The invention relates to a herbicide and a preparation method thereof, in particular to a herbicide water agent prepared by binary compounding of phenoxy hydroxy acid paraquat and diphenyl ether oxacarb and a preparation method thereof. Background technique [0002] Paraquat is a quick-acting contact-killing herbicide, which can quickly kill the above-ground parts of annual grasses and broad-leaved weeds, as well as the above-ground parts of perennial weeds propagated by seeds, so that the underground parts of annual weeds lose their nutrient supply. Hunger wilts and dies, but it has no effect on unearthed weeds; Huwei is a diphenyl ether selective herbicide, and it is extremely effective in controlling broad-leaved weeds in soybean fields. The pre-emergence and post-emergence use are quickly absorbed by the leaves, destroying the photosynthesis of weeds, causing the leaves to turn yellow and quickly wither and die. Rainfall within 4-6 hours after spr...
