Abstract

The invention relates to a weeding water aqua prepared by binary combination of gramoxone and MCPA-Na and preparation method thereof. The weeding water aqua is composed of the following components by mass percent: 3-10% of gramoxone, 2-10% of MCPA-Na, 0.01-0.3% of 2-Amino-6-methyl-4-propyl-1, 2, 4triazolo [1,5a] pyriin-5(4H)-on, 5-15% of synergist, 8-20% of penetrant, and balance water. The preparation includes that: in the mass ratio, the gramoxone is added with water and stirred; the MCPA-Na is added with water and stirred; the two are mixed and stirred, the 2-Amino-6-methyl-4-propyl-1, 2, 4triazolo [1,5a] pyriin-5(4H)-on is added into the well mixed and stirred gramoxone and MCPA-Na and stirred; the penetrant and synergist and the mixture are all added into a kettle to be stirred for 10-15 minutes; water is added and stirring is carried out for 20-30 minutes; and then standing, filtering, filling and sampling analysis are carried out, thus finished product is obtained. The invention overcomes the defect of the existing weed killer that single weed can be killed, is a quick-acting touch out type broad-spectrum weed killer, has fast action on broadleaf weed in gardens of rice, wheat, barley, corn, peanut, potato, cotton and mulberry and is safe to crops, dosage is 200-300g per mu, and application cost is 11.9-9.75% (mu / once) lower than that of other similar products.

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 phenoxyhydroxyacids and organic heterocyclic 2-methyl-4-chloride sodium and a preparation method thereof. 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 t...
