Embodiment 1

[0024] Example 1: 66% emulsifiable concentrate

[0025] The formula is composed of: 55% of active ingredient A, 11% of active ingredient B, 5% of emulsifier dioctyl maleate sulfonate, 3% of emulsifier phenylethylphenol polyoxyethylene ether, solvent II Toluene made 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: 36% suspending agent

[0028] The formula is composed of: 4% of active ingredient A, 32% of active ingredient B, 3% of wetting agent alkylnaphthalene sulfonate, 4% of dispersant to EO-PO block polyether, 5% of antifreeze agent ethylene glycol , 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 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: 80% water dispersible granules

[0031] The formula is composed of: 72% active ingredient A, 8% active ingredient B, 5% wetting agent alkyl succinate sulfonate, 6% dispersant alkylphenol polyoxyethylene ether phosphate, disintegrant Sodium sulfate 4%, binder carboxymethyl cellulose 0.2%, filler kaolin to make up to 100%.

[0032] The preparation method is as follows: after all the materials are mixed uniformly, they are pulverized by an airflow mill, and mixed uniformly again, then, a certain amount of water is added to knead the mixture, extruded and granulated, and dried and sieved to obtain water-dispersible granules.

Abstract

The invention provides synergetic herbicidal composition containing saflufenacil and bicyclopyrone. The herbicidal composition is characterized by being a conventional pesticide preparation prepared from an active component A, an active component B and usable auxiliaries in processing of the pesticide preparation, wherein A contains saflufenacil and bicyclopyrone, B is one or a combination of thiencarbazone-methyl and aminocyclopyrachlor, and the herbicidal composition is used for controlling needless plants.

Description

technical field [0001] The invention belongs to the technical field of pesticide application, and relates to a pesticide composition, in particular to a herbicidal composition containing saflufenacil and fluoxyfen, 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 e...
