A herbicide water agent formulated from Ke Wu Zong, 2M 4 Chloride Sodium and Ammonium Bicarbonate

Abstract

It is a weed-killing water agent prepared by compounding Ke Wu Zong with 2-M-4-Cl Sodium and Ammonium Bicarbonate. Its mass percentage composition: 3-10.% of Kewuzong, 2-10% of sodium 2-methyl-4-chloride, 0.01-0.03% of triazole-pyrimidinone, 3-5.5.% of ammonium bicarbonate, 5-15% of synergist %, penetrant 1-3%, water balance. Preparation method: Stir Ke Wu trace with water; add 2M 4 Chloride sodium and water; mix and stir the above two; add triazole-pyrimidinone and stir; add ammonium bicarbonate and stir; add penetrant and synergist; add water and stir , standing, filtering and filling to obtain the finished product. Use 250-300g of this product on broad-leaved weeds in wheat, cotton, soybean, corn and mulberry orchards per mu, mixed with 30-40kg of water, and the broad-leaved weeds showing death symptoms after 4 hours of trial use on cotton crops in Xinjiang area, After 8 hours, the leaves of perennial vicious weeds such as quinoa chinensis and chickweed turn pink and purple, and they will die. Use this product to weed and fertilize at the same time. The spraying cost is 18.1%-25.6% (mu / time) lower than the single use of gramusbone and 2-methyl-4-chloride sodium, and 20.2% (mu / time) lower than 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
