Embodiment 1

[0024] Example 1: 63% emulsifiable concentrate

[0025] The formula is composed of: 56% of active ingredient A, 7% of active ingredient B, 6% of emulsifier dioctyl sulfosuccinate sodium salt, 4% of emulsifier phenethylphenol polyoxyethylene ether, and the solvent xylene is supplemented 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: 49% suspending agent

[0028] The formula is composed of: 7% active ingredient A, 42% active ingredient B, 4% calcium dodecylbenzenesulfonate wetting agent, 4% tristyrylphenol polyoxyethylene ether phosphate dispersant, antifreeze agent Ethylene glycol 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: 72% water dispersible granules

[0031] The formula is composed of: 8% active ingredient A, 64% active ingredient B, 6% wetting agent sodium lauryl sulfate, 4% dispersant calcium lignosulfonate, 5% disintegrating agent ammonium sulfate, and binder carboxymethyl Base cellulose 0.2%, filler kaolin 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 herbicidal composition comprising flucarbazone and diflufenican. The herbicidal composition includes the following active components: (A) flucarbazone and diflufenican, and (B) one or more selected from dimethenamid, dimethenamid-p, flupoxam, bicyclopyrone, 2,4-dichlorprop and a salt thereof, and 2,4-dichloroprop-p and a salt thereof, and additives being available in pesticide preparation processing. The herbicidal composition is processed to obtain a common herbicide preparation which is used for preventing and controlling undesirable 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 flucarbasulfuron-methyl and diflufenican, 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...
