Embodiment 1

[0040] Formulation example 1: 7% pyrazosulfuron-methyl-pyrimidine saflufenacil-sperm metolachlor oil suspension

[0041]

[0042] The active components, wetting agent, dispersant, soybean oil and other components are mixed evenly according to the ratio of the formula, and after grinding or high-speed shear dispersion, the 7% pyrazosulfuron-methyl-pyrimidin-ethyl Metolachlor oil suspension.

Embodiment 2

[0043] Formulation example 2: 10.5% pyrazosulfuron-methyl-pyrimidin saflufenacil-sperm metolachlor oil suspension

[0044]

[0045] After the above-mentioned raw materials are mixed uniformly in proportion, they are dispersed by high-speed shearing for 30 minutes, and sand-milled with a sand mill to obtain the 15% pyrazosulfuron-methyl-pyrimidin-purified metolachlor oil suspension.

Embodiment 3

[0046] Formulation example 3: 30% pyrazosulfuron-methyl-pyrimidine saflufenacil-sperm metolachlor wettable powder

[0047]

[0048] First use white carbon black to absorb the pure metolachlor evenly, and then use the above raw materials to prepare wettable powder according to the conventional method, that is, pre-mix, air-flow pulverization, and post-mix to obtain the 30% pyrazosulfuron-pyrimidine Saxiflun·Smart metolachlor wettable powder.

Abstract

The invention belongs to the technical field of insecticides and provides a compounded herbicide for paddy fields. The compounded herbicide contains three active ingredients, namely pyrazosulfuron-ethyl, pyribenzoxim and S-metolachlor, wherein the weight ratio of the three active ingredients is (0.3-1.5): (0.6-3): (20-100), and the mass percentage of the three active ingredients is 1-50% of the compounded herbicide. According to the herbicide composition disclosed by the invention, pyrazosulfuron-ethyl, pyribenzoxim and S-metolachlor are compounded, are used for preventing and eliminating the weeds of the grass family, sedge family and broad-leaved class and cooperate with one another to synergize, so that the weeding activity is increased, the herbicide controlling spectrum is enlarged, and the generation of the drug resistance of the weeds is delayed; the herbicide composition is safe to paddy and after-reap crops and is an ideal herbicide.

Description

【Technical field】 [0001] The invention belongs to the field of pesticide herbicides, and relates to a three-component compound herbicide composition composed of pyrazosulfuron-methyl, saflufenacil, and metolachlor-sperm and an application thereof. 【Background technique】 [0002] my country is a large agricultural country, and rice is one of the crops with the largest planting area in our country. In order to ensure the high and stable yield of rice, the country has invested in various aspects, especially the promotion and application of science and technology. However, weeds in paddy fields have always been an important factor affecting yield. According to statistics, the area of ​​paddy field weeds in the country is above medium (level 2-5) has reached 15.467 million hectares, accounting for more than 40% of the total planting area, of which serious damage ( 4-5) with an area of ​​3.8 million hectares, accounting for more than 11.5% of the rice planting area. Among these w...
