Embodiment 1

[0024] Example 1: 44% EC

[0025] The formula is composed of: active ingredient A is 28%, active ingredient B is 2%, active ingredient C is 14%, emulsifier castor oil polyoxyethylene ether 3%, emulsifier calcium dodecylbenzenesulfonate 5%, solvent Xylene was 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: 57% suspending agent

[0028] The formula is composed of: 3% active ingredient A, 18% active ingredient B, 36% active ingredient C, 4% wetting agent sodium lauryl sulfate, dispersant alkylphenol polyoxyethylene ether formaldehyde condensate sulfonate 4%, antifreeze glycerol 5%, 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: 75% water dispersible granules

[0031] The formula is composed of: active ingredient A is 24%, active ingredient B is 48%, active ingredient C is 3%, wetting agent phenethylphenol polyoxyethylene ether is 6%, dispersant is p-methoxy fatty amidobenzenesulfonate sodium sulfate 5%, disintegrant sodium sulfate 5%, binder carboxymethyl cellulose 0.2%, filler diatomaceous earth 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 synergic weeding compound containing thiencarbazone, bicyclopyrone and mesotrione. The synergic weeding compound is characterized by comprising active ingredients A, B and C, wherein A is thiencarbazone, B is bicyclopyrone and C is mesotrione. The synergic weeding compound further comprises auxiliaries which are acceptable in the processing of pesticide preparations. The synergic weeding compound can be prepared into the conventional pesticide preparations and can be used for removing and preventing weeds in corn field, lawn, forest and uncultivated area.

Description

technical field [0001] The invention belongs to the technical field of pesticide application, and relates to a pesticide composition, specifically a herbicidal composition of thiazosulfuron-methyl, flumetrazone and mesotrione, which is applied to cornfields, lawns, woodlands and non-cultivated weeds. Grass control. Background technique [0002] In the process of agricultural production, weeds (unwanted plants) occur seriously, endangering the growth of target crops such as crops, lawns, trees, and affecting the normal use of undesired vegetation plots (such as non-cultivated land, etc.). Herbicides are the most economical, quick and effective method of controlling weeds. [0003] The use of a single herbicide is prone to drug resistance or has a limited control spectrum, which cannot solve the weed hazards in actual production. Mixed herbicides have the advantages of expanding the control spectrum, enhancing the control effect, and delaying weed resistance, and have become...
