Weeding water agent prepared by compounding gramoxone, 2-methyl-4-chloro-phonexyacetic and ammonium hydrogen carbonate

Abstract

The invention relates to a weeding water agent prepared by compounding gramoxone, 2-methyl-4-chloro-phonexyacetic and ammonium hydrogen carbonate, comprising the following components in percentage by weight: 3-10 percent of gramoxone, 2-10 percent of 2-methyl-4-chloro-phonexyacetic, 0.01-0.03 percent of triazole-pyrimidone, 3-5.5 percent of ammonium hydrogen carbonate, 5-15 percent of synergistic agent, 1-3 percent of osmotic agent and the balance of water. The weeding water agent is prepared by the following steps: adding water into the gramoxone and stirring; adding water into the 2-methyl-4-chloro-phonexyacetic and stirring, mixing and stirring the gramoxone solution and the 2-methyl-4-chloro-phonexyacetic solution; adding the triazole-pyrimidone and stirring; adding the ammonium hydrogen carbonate and stirring; adding the synergistic agent and the osmotic agent and stirring; and adding water and stirring, standing, filtering and filling to obtain the finished product. 250-300g of the weeding water agent and 30-40kg of water are mixed and applied to each mu of wheat, cotton, soy beans, maize and mulberry orchards for removing broad leaved weed; after the weeding water agent is applied to cotton crops in Xinjiang region for 4h, intercrescence broad leaved weed represents death symptom, and leaves of perennial malignant weeds, such as chenopodium glaucum, malachium aquaticum and the like are changed into peachblow and purple and are to death after the weeding water agent is applied for 8h. The weeding water agent can simultaneously weed and fertilize. The medicine applying cost is lowered by 8.1-25.6 percent (mu / time) compared with that of separate use of the gramoxone and the 2-methyl-4-chloro-phonexyacetic and lowered by 20.2 percent (mu / time) compared with that of glyphosate.

Description

technical field [0001] The invention relates to a herbicide and a manufacturing method thereof, in particular to a herbicide water agent prepared by ternary compounding of phenoxy hydroxyacids, gramazan, organic heterocycles, 2-methyl-4-chloride, and ammonium bicarbonate. Background technique [0002] Kewuzong is a quick-acting contact-killing herbicide, which can quickly kill the above-ground parts of annual grasses and broad-leaved weeds and the above-ground parts of perennial weeds propagated by seeds, so that the underground parts of annual weeds lose nutrient supply and gradually It wilts and dies due to starvation, but it has no effect on unearthed weeds; sodium 2-methyl-4-chloride is a selective hormone-type herbicide of phenoxyacetic acid, which is very sensitive to the seedling stage of grass plants, and the resistance gradually increases after the 3-4 leaf stage. increase, the strongest at the end of tillering. Therefore, it is advisable to apply pesticides at the...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the above-mentioned herbicides have a narrow herbicidal range, cause phytotoxicity to subsequent crops, and cannot kill all weeds at one time, and provide a kind of herbicide combined with 2-methyl-4-chloride sodium and bicarbonate Herbicide water agent prepared by ammonium ternary compound and its preparation method, referred to as "Herbicide" water agent-2
