Embodiment 1

[0023] Example 1: 26% EC

[0024] The formula is composed of: 20% of active ingredient A, 6% of active ingredient B, 3% of calcium dodecylbenzenesulfonate emulsifier, 7% of phenethylphenol polyoxyethylene ether as emulsifier, and 100% of solvent xylene %.

[0025] The preparation method is as follows: put all the materials into the batching kettle, stir and dissolve until completely transparent, and transfer to the storage tank for filling after passing the test.

Embodiment 2

[0026] Embodiment 2: 38% suspending agent

[0027] The formula is composed of: active ingredient A is 28%, active ingredient B is 10%, wetting agent fatty alcohol polyoxyethylene ether 4%, dispersant alkylphenol polyoxyethylene ether phosphate 5%, antifreeze agent ethylene glycol 5% %, thickener magnesium aluminum silicate 1%, water to make up to 100%.

[0028] The preparation method is: put the active ingredient, wetting agent, dispersant, antifreeze and water into the stirring tank, after fully stirring, pump the material into the sand mill for full grinding, after the grinding is completed, pump it into the high-speed shearing machine In the process, after adding the thickener, high-speed shearing is carried out, and the suspending agent is obtained after the shearing is completed.

Embodiment 3

[0029] Example 3: 60% water dispersible granules

[0030] The formula is composed of: 40% of active ingredient A, 20% of active ingredient B, 0.5% of wetting agent sodium lignosulfonate, 8% of dispersing agent acrylate, 3% of disintegrating agent sodium sulfate, binder polyvinyl alcohol 1 %, filler bentonite make up to 100%.

[0031] The preparation method is as follows: after all the materials are mixed uniformly, pulverized by an airflow mill, mixed uniformly again, and then a certain amount of water is added to knead the mixture, extruded and granulated, and dried and sieved to obtain the water-dispersible granules.

Abstract

The invention provides a synergistic weeding composition containing tefuryltrione and fenoxasulfone. The synergistic weeding composition is characterized by being prepared from active ingredients of A and B, wherein the A is the tefuryltrione and the fenosasulfone, and the B is one or a combination of more than one of orthosulfamuron, cyclosulfamuron, penoxsulam, cyhalofop butyl, propyrisulfuron, cafenstrole and imazosulfuron. The synergistic weeding composition is further prepared from an addition agent which can be applied to pesticide preparation processing, can be prepared into general pesticide preparation and can be applied to preventing and treating undesired plants.

Description

technical field [0001] The invention belongs to the technical field of pesticide application, and relates to a pesticide composition, specifically a herbicidal composition containing furasulcotrione and fenoxasulfone, which is used for controlling unwanted plants. Background technique [0002] In the process of agricultural production, unwanted plants (weeds) occur seriously, endangering the growth of target crops such as crops and trees, and affecting undesired vegetation plots (such as non-cultivated land, railways, roads, forest fire escapes, industrial sites, field sites, etc.) hospital, etc.) for normal use. Herbicides are the most economical, quick and effective method of controlling unwanted vegetation. [0003] The use of a single herbicide is likely to produce resistance or has a limited control spectrum, which cannot solve the harm of unwanted plants in actual production. Mixed herbicides have the advantages of expanding the control spectrum, enhancing the contro...
