Problems solved by technology

[0004] So far, there have been herbicide compositions using mestrizone in combination with sulfone ketones, amide herbicides, etc. The herbicide composition that is used in combination with agents such as methidone, but there is no herbicide composition composed of methidone and clethodim, and considering the low solubility of methidone in non-polar solvents, clethodim The ketone original drug is unstable and easy to decompose when encountering polar solvents. Therefore, how to compound mecitrione and clethodim and the effect of the compound are unpredictable

Embodiment 1

[0015] This embodiment provides a water-dispersible granule of a herbicide composition. In parts by weight, its raw material formula is composed of: 40 parts of the original drug of mecitrione, 20 parts of the original drug of clethodim, 5 parts of naphthalenesulfonate, 3 parts polycarboxylate, 32 parts cornstarch. The individual raw material components are commercially available.

[0016] The water dispersible granules of the herbicide composition are prepared by the following method:

[0017] According to the formula, fully mix the original drug of mecitrione, naphthalene sulfonate, polycarboxylate and corn starch, coarsely pulverize, remix, pulverize with a jet mill, enter into a cone mixer for mixing, and make clethodim oil The original drug is added by spraying, stirring is started to fully mix evenly, and then rapid stirring and dry granulation are carried out to obtain the product.

Embodiment 2

[0020] This embodiment provides a water-dispersible granule of a herbicide composition. In parts by weight, its raw material formula is composed of: 50 parts of the original drug of mecitrione, 25 parts of the original drug of clethodim, 5 parts of naphthalenesulfonate, 3 parts polycarboxylate, 17 parts cornstarch. The individual raw material components are commercially available.

[0021] The preparation method is the same as in Example 1. The water dispersible granule technical index of this herbicide composition is as follows: Suspension rate 92.1%; Disintegration time ≤ 50s; Wetting time ≤ 40s; Moisture content ≤ 2.0%; ) ≥ 98%; persistent foaming (after 1 min) ≤ 20ml; suspension rate ≥ 85% after heat storage at 54±2°C for 30 days.

Embodiment 3

[0023] This embodiment provides a water-dispersible granule of a herbicide composition. In parts by weight, its raw material formula consists of: 40 parts of the original drug of mecitrione, 30 parts of the original drug of clethodim, 5 parts of naphthalenesulfonate, 3 parts polycarboxylate, 22 parts cornstarch. The individual raw material components are commercially available.

[0024] The preparation method is the same as in Example 1. The water dispersible granule technical indicators of the herbicide composition are as follows: suspension rate 92.5%; disintegration time ≤ 50s; wetting time ≤ 40s; water content ≤ 2.0%; ) ≥ 98%; persistent foaming (after 1 min) ≤ 20ml; suspension rate ≥ 85% after heat storage at 54±2°C for 30 days.

Abstract

The invention relates to a herbicide composition. The herbicide composition is characterized in that the herbicide composition comprises the following raw materials by weight percent: 10-80% of metribuzin technical, 10-60% of clethodim technical, 2-10% of wetting agents, 2-10% of polycarboxylate and 10-40% of fillers; and the herbicide composition is a water dispersible granule or wettable powder. The herbicide composition has obvious synergistic effect on controlling the monocotyledonous and dicotyledonous weeds in the farmlands, simultaneously does not have any inhibiting effect on the crops, ensures the yield of the crops while ensuring weed control, has obvious application value and social benefits and is an ideal herbicide for the monocotyledonous and dicotyledonous weeds in the farmlands.

Description

technical field [0001] The invention relates to farmland herbicides, especially herbicide compositions for controlling farmland monocotyledon and dicotyledonous weeds. Background technique [0002] Mecitrione (4-amino-6-tert-butyl-4,5-dihydro-3-methylthio-1,2,4-triazin-5(4H)-one, MTB) is a selective herbicide , its active ingredients are absorbed by the roots of weeds and conducted to the upper part of the transpiration flow, and can also be absorbed by the leaves for limited conduction in the body. The herbicidal activity is mainly exerted by inhibiting the photosynthesis of sensitive plants. Affected, leaves chlorosis after emergence, and finally nutrient depletion and death. Mecitrione is widely used as a herbicide to control pre-emergence and post-emergence weeds in soybean, potato, tomato and other crops, and can effectively control cocklebur, quinoa, foxtail and other weeds in potato fields. [0003] The chemical name of clethodim is 2-{1-[(3-chloro-2-allyl)oxy]imino...
