Problems solved by technology

In the current market application, quinclorac is mainly used to control gramineous weeds such as barnyardgrass in paddy fields, and there is no report on the use of quinclorac in upland fields, especially when it is combined with fensulfame and two The use of the quinclorac composition in the cornfield is also unreported

Embodiment 1

[0027] Example 1: Preparation of wettable powder.

[0028] 20% active ingredient (A) and 40% active ingredient (B), 2% sodium lauryl sulfate as wetting agent, 10% carboxylate as dispersant, 5% sodium lauryl sulfate as dispersant Sulfonate, 15% white carbon black and other inert fillers are thoroughly mixed together and ultrafinely pulverized to obtain a wettable powder.

Embodiment 2

[0029] Embodiment 2: the preparation of suspending agent.

[0030] 15% active ingredient (A) with 20 active ingredient (B), 15% carboxylate as emulsifier, 2% organic bentonite as thickener, 5% ethylene glycol as antifreeze, water After making up 100%, put it into a sand mill for grinding to obtain the suspending agent.

Embodiment 3

[0031] Example 3: Preparation of water-dispersible granules.

[0032] 30% active ingredient (A) with 50% active ingredient (B), 6% carboxylate as wetting agent, 6% NNO as dispersant, 4% lignosulfonic acid as dispersant Calcium and other inert fillers are thoroughly mixed together and ultrafinely pulverized, then an appropriate amount of water and binder is added to the mixture, and the water-dispersible granules can be obtained after fluidized bed granulation or extrusion granulation and drying.

Abstract

The invention provides to a herbicidal composition containing flumetsulam and quinclorac and a preparation method and application. The composition is formed by the compound (A) flumetsulam and the compound (B) quinclorac. The weight ratio of the compound (A) and the compound (B) is 1:1-100. After mixture according to appropriate proportion, the composition can be processed into wettable powder, suspending agents, water-dispersible granules and other conventional formulations of pesticide through the modern pesticide preparation processing technology. The herbicidal composition is used for preventing and killing off such broadleaf weeds and grass weeds in the corn fields as abutilon, chenopodium album, chickweed, catchweeds, datura stramonium, amaranthus retroflexus, fragrant chamomile, wild radish, smartweeds, kochia scoparia, nightshade, white dead nettle, speedwell, hibiscus trionum, xanthium sibiricum, rorippa islandica, thlaspi caerulescens, digitaria sanguinalis, setaria, goosegrass herb and the like. The control effect of the composition is obviously better than that of the single compound (A) or compound (B), thus substantially reducing the application dosage of various active substances.

Description

technical field [0001] The present invention relates to herbicidal compositions with improved properties, in particular to herbicidal compositions containing flumesulam and quinclorac and uses thereof. Background technique [0002] The common name of compound (A) is flumesulam, and its chemical name is 2',6'-difluoro-5-methyl[1,2,4]triazolo[1,5-a]pyrimidine-2 - Sulfonanilide. [0003] Flumesulam is a broad-spectrum herbicide, which can control most annual and perennial broad-leaved weeds, and also has inhibitory effect on young grass weeds. It has excellent activity against Polygonum, Kochia, Solanum nigrum, Wild Sesame, Popona, Wild Watermelon Seedlings, Cocklebur, Brassicaceae, Brassicaceae and other cruciferous species. It has remarkable control effect on weeds, and also has good activity on foxtail and iron water chestnut. [0004] Currently, the dosage form of flumesulam used in the market mainly includes 80% flumesulam water-dispersible granules. [0005] The gener...
