Embodiment 1

[0020] In the reaction kettle, add an appropriate amount of deionized water, then add 40 parts of disulfuron-methyl (active ingredient 1) and 15 parts of acesulfame (active ingredient 2) in sequence, and stir; then add high clay as a filler, and then add Adjuvants, including 0.5 parts of wetting agent, 0.5 parts of dispersing agent, 0.5 parts of thickener, 1-5 parts of film forming agent, 0.5 parts of antifreeze, 0.5 parts of defoaming agent, 0.5 parts of warning agent, 0.5 parts of preservative, Stir for 30 minutes, in which the antifoaming agent is finally added to make methyl disulfuron solution; finally add 5 parts of mefenpyr-ethyl as a safener, and stir at a low speed of 100-250 rpm for 10-15 minutes.

Embodiment 2

[0022] In the reaction kettle, add an appropriate amount of deionized water, then add 70 parts of disulfuron-methyl (active ingredient 1) and 25 parts of acesulfame (active ingredient 2) in sequence, and stir; then add clay as a filler, and then add auxiliary agent, including 8 parts of wetting agent, 8 parts of dispersant, 4 parts of thickener, 4 parts of film forming agent, 4 parts of antifreeze, 2 parts of defoamer, 2 parts of warning agent, 3 parts of preservative, stirring for 30 minutes, Among them, the antifoaming agent is finally added to make methylsulfuron-methyl solution; finally, 8 parts of mefenpyr-ethyl are added as a safener, and it is enough to stir at a low speed of 100-250 rpm for 10-15 minutes.

Embodiment 3

[0024] In the reaction kettle, add an appropriate amount of deionized water, then add 30 parts of disulfuron-methyl (active ingredient 1) and 30 parts of diflufenican (active ingredient 2) in sequence, and stir; then add organic bentonite and diatomaceous earth The mixture is used as a filler, and then add auxiliary agents, including 2 parts of wetting agent, 2 parts of dispersing agent, 2 parts of thickener, 2 parts of film forming agent, 2 parts of antifreeze, 2 parts of defoaming agent, 2 parts of warning agent, anticorrosion Add 2 parts of antifoaming agent and stir for 30 minutes, among which the antifoaming agent is finally added to make methylsulfuron-methyl solution; finally add 12 parts of isoxadifen as a safener, and stir at a low speed of 100 to 250 rpm for 10 to 15 minutes. .

Abstract

The invention discloses a mesosulfuron-methyl composition containing a safener and a preparation method thereof. The mesosulfuron-methyl composition is prepared from an active ingredient I, an activeingredient II, an auxiliary agent and the safener, wherein the active component I is mesosulfuron-methyl, the active component II is selected from one or a combination of two of pyroxsulam, diflufenican and florasulam, the adjuvant comprises an auxiliary agent and a filler, and the safener is selected from one or a combination of two of mefenpyr-diethyl, isoxadifen-ethyl and cyclopropanesulfamide.Due to the addition of the safener, weeds in a wheat field can be effectively prevented and killed, the herbicide resistance of crops to herbicides can be remarkably improved, phytotoxicity of mesosulfuron-methyl to wheat is reduced, and the yield is increased. In addition, the active ingredient II can significantly improve the pesticide effect, improve the weed control effect of the herbicide and reduce the dosage of the herbicide.

Description

technical field [0001] The invention relates to a methylsulfuron-methyl composition added with a safener and a preparation method thereof. [0002] technical background [0003] In recent years, sulfonylurea herbicides with ultra-high herbicidal activity and high selectivity have become one of the most widely used and most diverse herbicides. In the world herbicide market, the market share of sulfonylurea herbicides is second only to amino acid herbicides (glufosinate-ammonium, glyphosate, etc.). At present, China is the country that uses more types and quantities of sulfonylurea herbicides, second only to the United States. As of 2016, there are more than 500 invention patents related to sulfonylurea herbicides, and as many as 40 commercial technicals. At the end of the last century, Li Zhengming's research group at Nankai University discovered that heterocyclic monosubstituted compounds have similar activities to 4,6-disubstituted compounds. The monosulfuron-methyl develo...
