Embodiment 1

[0017] Preparation of 8% Suspension Concentrate of Cycloclotrione · Fluchlorpyrizate.

[0018] In terms of parts by mass, every 100 parts of Cyclotrione · Fluclopyridine Suspension Contains, 7 parts of Cyclotrione, 1 part of Fluclopyridin, 8 parts of calcium dodecylbenzenesulfonate, lignin sulfonate 3.5 parts of hydrochloric acid, 25 parts of dibutyl phthalate, 0.6 parts of butanol, 0.8 parts of polyvinyl alcohol, and 54.1 parts of sterile water.

[0019] Weigh each component according to the above-mentioned parts by mass, add chlorpyridyl, cyclazone, calcium dodecylbenzenesulfonate, ligninsulfonate, butanol, and polyvinyl alcohol into the frosted kettle, and grind to a certain After the fineness is obtained, transfer the material to a stirring tank, add the remaining dibutyl phthalate and sterile water, and mix thoroughly to obtain an 8% cyclotrione · chloropyridine suspension concentrate.

Embodiment 2

[0021] Preparation of 15% Cyclotrione · Fluchloropyridine EC.

[0022] In terms of parts by mass, every 100 parts of cyclotrione · fluorine chloropyridine emulsifiable concentrate contains 10 parts of cyclotrione, 5 parts of fluoroclopyridine, 15 parts of agricultural milk 400#, 48 parts of N-methylpyrrolidone, 18.5 parts of methanol, 3.5 parts of epichlorohydrin.

[0023] Weigh each component according to the above-mentioned parts by mass, add cyclazone and fluchloropyridine to N-methylpyrrolidone, mix well, add methanol, agricultural milk 400# and epichlorohydrin in turn, stir well and form Uniform and transparent oily liquid, that is, 15% Cyclotrione · Fluchloropyridine EC.

Embodiment 3

[0025] Preparation of 30% Cycloclotrione·Calcloxacin Water Dispersible Granules.

[0026] In terms of parts by mass, every 100 parts of Cyclotrione·Chalfludinate water-dispersible granules contains 15 parts of Cyclotrione, 15 parts of Fluclopyridin, 3 parts of lignocarbon sulfonate, dodecane 3.5 parts of sodium sulfate, 2 parts of sodium sulfate, 8 parts of polyethylene glycol, and 53.5 parts of kaolin.

[0027] Weigh each component according to the above-mentioned parts by mass, put the material into the mixer and mix evenly, then pulverize through the jet mill, pass through a 600-mesh standard sieve, add into the kneader to knead into the material, and finally put the material into the extrusion granulator Medium-extrusion granulation, drying and sieving after granulation to obtain 30% Cyclotrione·Chalopyxate water-dispersible granules.

Abstract

The invention provides the weeding composition taking profoxydim and halauxifen-methyl as main active components, the mass ratio of profoxydim to halauxifen-methyl in the weeding composition is (20: 1)-(1: 15), and the composition has a synergistic effect within the ratio range through experimental verification of the inventor. The weeding composition is used in cooperation with other pesticide auxiliary agents, is prepared into a common pesticide formulation, has an extremely remarkable control effect on gramineous weeds and broadleaf weeds in paddy fields or wheat fields, is small in dosage and high in control effect, and has a wide application prospect in the pesticide market.

Description

technical field [0001] The invention belongs to the technical field of agricultural compositions, and relates to a herbicidal composition, in particular to a herbicidal composition containing cycloclotrione and halfenidyl. Background technique [0002] Farmland weeds are an integral part of the agricultural ecosystem, directly or indirectly affecting agricultural production. Weeds are generally considered to be "herbs where one does not want them to grow", that is, herbaceous plants that people consciously cultivate for crops. According to the report of the Food and Agriculture Organization of the United Nations (FAO), the world's food crops suffer from diseases, insects, weeds and other hazards, with an average loss of 30-50% of the pre-harvest yield, of which about 10% is lost due to weeds, and the loss of food is 290 million tons. In my country, the loss caused by weeds also accounts for 10% of the total grain output, so the grain lost due to weeds every year has tens of...
