Embodiment 1

[0024] Example 1: 60% EC

[0025] The formula is composed of: 54% active ingredient A, 6% active ingredient B, 5% emulsifier alkylbenzene sulfonate, 3% emulsifier tristyrylphenol polyoxyethylene ether, and solvent xylene to make up to 100% .

[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: 32% suspending agent

[0028] The formula is composed of: 4% active ingredient A, 28% active ingredient B, 3% wetting agent sodium lauryl sulfate, 4% dispersant sodium naphthalenesulfonate formaldehyde condensate, 5% antifreeze ethylene glycol, Thickener magnesium aluminum silicate 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: 72% water dispersible granules

[0031] The formula is composed of: 63% of active ingredient A, 9% of active ingredient B, 6% of calcium dodecylbenzenesulfonate as a wetting agent, 4% of sodium methylene bis-naphthalenesulfonate as a dispersing agent, and ammonium sulfate as a disintegrating agent 4%, binder polyethylene glycol 0.5%, filler attapulgite to 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 a synergistic weeding composition containing pyrithiobac-sodium and refined napropamide. The synergistic weeding composition is characterized by comprising an active component Aand an active component B, wherein the active component A comprises the pyrithiobac-sodium and the refined napropamide; the active component B is one or a combination of more than one of cloproxydim,tepraloxydim, fluoroglycofen-ethyl, trifluralin, diuron, s-metolachlor, flumioxazin, propaquizafop and tiafenacil; the synergistic weeding composition further comprises auxiliary agents which can beused in processing of pesticide preparations; the synergistic weeding composition is prepared into a conventional pesticide preparation and is applied to prevention and control of unwanted 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 pyrizachlor and napropamide, 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 effec...
