preparation example Construction

[0024] The preparation method of compound herbicide of the present invention comprises the following steps:

[0025] Make up 100 parts of 100 parts of octanoyl bromide, 1-8 parts of nicosulfuron, 10-25 parts of atrazine and 10-25 parts of emulsifier with solvent, mix and fully Stir well;

[0026] Put the above-mentioned uniformly stirred raw materials into a ball mill, and grind for 3 hours;

[0027] The above-mentioned ground raw materials are pressed into a sander with a pressure of 2 kg, and ground to a particle size of less than 10 um, and a 325-mesh sieve pass rate of more than 90%, to obtain a compound product.

Embodiment 1

[0029] Example 1: Weigh 10Kg of bromoxynil octanoyl, 1Kg of nicosulfuron, 10Kg of atrazine, 10Kg of emulsifier 7218, and 69Kg of corn oil, stir evenly, and grind until the particle size is qualified by sand milling to obtain this product .

Embodiment 2

[0030] Example 2: Weigh 13Kg of bromoxynil octanoyl, 2.5Kg of nicosulfuron, 12Kg of atrazine, 15Kg of emulsifier 7218, and 57.5Kg of corn oil, stir evenly, and grind until the particle size is qualified, to obtain This product.

Abstract

The invention provides preparation and use methods of a built herbicide. The built herbicide comprises the following components: solvent, 10-16 percent of bromoxynil octanoate, 1-8 percent of nicosulfuron, 10-25 percent of atrazine, and 10-25 percent of emulsifier. The preparation method includes steps as follows: mixing and stirring raw materials, ball milling and grinding with a stander to obtain grains with grain diameter below 10um screening with a 325 mesh sieve to obtain passing rate above 90 percent. The use method is as follows: 150-200ml of built herbicide added with 30kg of water is sprayed for every acre of land. The invention is simple in production process, effective in use, broad in spectrum herbicide, particularly effective on broad-leaved weed, safe for corn, side-effect-free to succession crop, low in preventive cost, and easy in use; in addition, the invention can reduce the pollution to environment and the impact on human health.

Description

technical field [0001] The present invention relates to a field herbicide for crops and its preparation method and application method, in particular to bromoxynil, nicosulfuron, Atrazine ternary compound herbicide and its preparation method and application method. Background technique [0002] Corn is an important grain and fodder crop in my country. With the development of industry and animal husbandry and the needs of the market, the annual planting area reaches 21.4 million hectares, accounting for 18.9% of the grain planting area, second only to rice and wheat, and has increased year by year The trend is that the annual output is 99 million tons, basically equal to that of wheat, accounting for about 22% of the total output of grain crops. However, there are many kinds of weeds in cornfields, including 22 families, 38 genera, and 43 species. my country can be divided into 6 weed damage areas. It is that the weeds are the most harmful at the seedling stage, and the occurr...
