Embodiment 1

[0024] Example 1: 56% emulsifiable concentrate

[0025] The formula is composed of: 8% of active ingredient A, 48% of active ingredient B, 5% of emulsifier sorbitan ester, 5% of emulsifier tristyrylphenol polyoxyethylene ether, and 100% of solvent xylene.

[0026] 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

[0027] Embodiment 2: 42% suspending agent

[0028] The formula is composed of: 35% of active ingredient A, 7% of active ingredient B, 4% of calcium dodecylbenzenesulfonate as a wetting agent, 5% of alkylphenol polyoxyethylene ether formaldehyde condensate sulfonate as a dispersant, Antifreeze glycerin 5%, thickener xanthan gum 0.3%, water to make up to 100%.

[0029] 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

[0030] Example 3: 64% water dispersible granules

[0031] The formula is composed of: 16% active ingredient A, 48% active ingredient B, 7% wetting agent sodium lauryl sulfate, 5% dispersant sodium p-methoxy fatty amidobenzenesulfonate, and 4% disintegrating agent ammonium sulfate %, the binder polyethylene glycol 0.5%, and the filler diatomaceous earth make up to 100%.

[0032] 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 synergistic weeding composition containing saflufenacil. The weeding composition is characterized by comprising active ingredients A and B, wherein A is saflufenacil, and B is one or a combination of more than one of quizalofop-P-tefuryl, aminocyclopyrachlor, tiafenacil, F4050, SL-1201, F9600 and F9960; the weeding composition further contains auxiliaries capable of being used during processing of pesticide preparations, and a conventional pesticide preparation is prepared from the weeding composition and applied to control for unnecessary plants.

Description

technical field [0001] The invention belongs to the technical field of pesticide application, and relates to a pesticide composition, specifically a saflufenacil-containing herbicidal composition, 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 control effect, and delayin...
