Embodiment 1

[0023] Formulation example 1: 80% chlorpyrazosulfuron-quinclorac-fluroxyacetic acid water-dispersible granules.

[0024] Clopyrazosulfuron 10%, quinclorac 50%, fluroxypyr 20%, sodium lauryl sulfate 5%, alkylphenol polyoxyethylene ether 5%, ammonium sulfate 3%, polyvinyl alcohol 2%, Kaolin makes up 100%. Mix the above-mentioned active ingredients, wetting agent, dispersant, disintegrant, binder and solid carrier evenly, pulverize with an ultra-fine jet mill, knead, and then add to a fluidized bed granulation dryer for granulation and drying and sieving to obtain 80% clopyrazosulfuron-quinclorac-clofluroxy acetic acid water-dispersible granules.

Embodiment 2

[0025] Formulation example 2: 70% clopyrazosulfuron-quinclorac-clofluroxywettable powder

[0026] Clopyrazosulfuron 10%, quinclorac 50%, fluroxypyr 10%, sodium dodecylbenzenesulfonate 10%, calcium lignosulfonate 5%, kaolin supplement 100%. Mix the above-mentioned active ingredients, wetting agent, dispersant and solid carrier, mechanically pulverize, then airflow pulverize, and mix uniformly to obtain 70% clopyrazosulfuron-quinclorac-clofluroxyacetic acid wettability powder.

Embodiment 3

[0027] Formulation example 3: 22% clopyrazosulfuron-quinclorac-clofluroxy acetic acid oil suspension.

[0028] Clopyrazosulfuron 2%, quinclorac 15%, fluroxypyr 5%, sodium dodecylbenzene sulfonate 10%, alkylphenol polyoxyethylene ether 10%, xanthan gum 2%, Methyl oleate makes up 100%. After the above-mentioned active ingredients, wetting agent, dispersant, thickener and liquid carrier are dispersed by high-speed shearing and sand-milled in a sand mill, a highly dispersed and stable suspension system formed in a non-aqueous medium can be obtained 22% clopyrazosulfuron · quinclorac · fluroxypyroxyacetic acid oil suspension concentrate.

Abstract

The invention relates to a weeding composition containing halosulfuron-methyl and quinclorac as well as fluroxypyr. The effective components of the weeding composition are halosulfuron-methyl and quinclorac as well as fluroxypyr, and the weight part ratio of halosulfuron-methyl, quinclorac and fluroxypyr is (1-10):(1-50):(1-20). The weeding composition has a synergistic effect, can be used for preventing and removing grassy weeds, broadleaf weeds and cyperaceous weeds in wheat fields, corn fields, paddy fields, sugarcane fields and sorghum fields, is remarkably superior to a individual weedicide separately used or a combination of two weedicides in effect, expands a weeding spectrum, reduces the pesticide consumption, alleviates the environmental pollution and delays the pesticide resistance of the weeds.

Description

technical field [0001] The present invention relates to pesticide herbicidal composition and application field thereof, specifically a kind of herbicidal composition with clopyrazosulfuron-methyl, quinclorac and fluroxypyr as active ingredients, which is applied to control wheat field, corn grass weeds, broadleaf weeds and sedge weeds in fields, paddy fields, sugarcane fields and sorghum fields. Background technique [0002] Halosulfuron-methyl: a new type of sulfonylurea herbicide, mainly used to control broad-leaved weeds and sedge weeds in wheat, corn, rice, sugarcane, lawn, etc. , mandala, ragweed, amaranth, wild watermelon seedlings, Polygonum, purslane, nightshade, cassia, morning glory, Cyperus cyperus, etc., because they can be quickly metabolized into harmless substances in crops, so they are harmful to Crop safe and can be applied both pre-emergence and post-emergence. [0003] Quinclorac: a hormone-type quinoline carboxylic acid herbicide, the compound can be ab...
