Embodiment 1

[0038] Formulation Example 1: 76% glufosinate-chlorate. Flucarbasulfuron (1:75)) water dispersible granules

[0039] Mix 10 grams of chlorinated phosphate, 750 grams of fluasulfuron-methyl, 30 grams of lignin, 40 grams of NNO, 20 grams of K12, 30 grams of low-substituted hydroxypropyl methylcellulose, and 100 grams of kaolin, mix them evenly and carry out jet milling , resulting in ultra-fine wettable powder, adding wettable powder to the inclined turntable while spraying an aqueous solution with 20 grams of phenolic resin, and then drying and sieving to obtain 76% chlorinated glufosinate. Fluazosulfuron water dispersible granules herbicidal composition.

Embodiment 2

[0040] Formulation Example 2: 50.5% glufosinate-chlorcarbazone-flucarbasulfuron (1:100) dry suspension

[0041] Add 5 grams of glufosinate chloride, 500 grams of flucarbasulfuron, 30 grams of phenylarylphenol polyoxyethyl ether, 40 grams of nonylpolyphenoloxyethylene ether phosphate, and 60 grams of dispersant NNO into the mixed solution, and use Make up deionized water and stir evenly, then coarsely pulverize with a high-speed shearing machine, and then enter a two-stage sander for fine grinding, add 235 grams of white carbon black and 130 grams of ammonium sulfate after grinding, and then enter a pressure spray drying tower for drying or granulation , made into powder or micro-solid, and after passing the test, it will become a 50.5%% glufosinate-fluazosulfuron dry suspension composition. When used in water, it has the same effect as the suspending agent, but its storage stability is better than that of the suspending agent.

Embodiment 3

[0042] Formulation example 3: 30% glufosinate-pyrazafen (14:1) dispersible oil suspension concentrate

[0043] 614.5 grams of methyl oleate were pumped into the shear tank, 45 grams of MF, 18 grams of NNO and 5 grams of 1860, and 5 grams of formaldehyde were drawn into the shear tank, and then 280 grams of phosphinochloridinate and 20 grams of pyridine were stirred while stirring. Grass ether, 2.5 grams of xanthan gum, and 10 grams of magnesium aluminum silicate are put into the shearing tank in sequence, and the materials are mixed evenly by shearing for 30 minutes. Turn on the circulating water, ball mill the material at a certain flow rate, control the temperature below 40 degrees, and pass a 325-mesh sieve to obtain a 30% triflumesulfuron-alachlor dispersible oil suspension herbicidal composition.

Abstract

The invention relates to an herbicide composition containing clacyfos. The 100% of herbicide composition comprises an ingredient A, one or more of an ingredient B and the balance, wherein the ingredient A is the clacyfos, the ingredient B is selected from one or more effective ingredients including flucarbazone, pyraflufen-ethyl, florasulam, flumetsulam, pyroxsulam, 2,4-D butyl ester, fenoxaprop-p-ethyl, barban, bensulfuron-methyl, pinoxaden, chlortoluron, thifensulfuron, mesosulfuron or sodium metsulfuron methyl iodide, and the balance includes a dispersing agent, a wetting agent, a stabilizing agent, a thickening agent and a solvent. The weight ratio of the ingredient A to the ingredient B is 1:160-160:1. Two groups of active substance can be compounded to effectively prevent and control annual or perennial broadleaf gramineous weeds in wheat fields. The herbicide composition can improve preventive effects of simple dosages and enlarge weeding spectrum and is safe to wheat.

Description

technical field [0001] The invention relates to a pesticide composition. Specifically, it is a herbicide synergistic composition containing glufosinate-chloride active ingredients, which belongs to the field of pesticide preparations. Background technique [0002] Wheat is the most important food crop in northern my country, which is related to the national economy, the people's livelihood and the country's food security. The annual national planting area is 25 million hectares, mainly concentrated in the Huanghuaihai River Basin and the Yangtze River Basin. In recent years, with the decline in the price of rapeseed and the rising price of wheat, the acreage of wheat has been increasing year by year. According to the survey, the damage area of ​​wheat weeds in my country accounts for more than 55% of the wheat area, the area of ​​severe damage in the medium term accounts for about 28%, and the loss accounts for 15% of the total wheat output. The common weeds in wheat fiel...
