Embodiment 1

[0032] 15% EC

[0033] The formula is composed of 9% active ingredient A, 6% active ingredient B, 3% emulsifier alkylbenzene sulfonate, 5% emulsifier lauryl sulfate, 9% cyclohexanone, xylene supplemented to 100%. The preparation method is: 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

[0035] 35% SE

[0036] The formula is composed of: 21% active ingredient A, 14% active ingredient B, 4% wetting agent octyl sulfosuccinate sodium salt, 4% dispersant sodium alkylnaphthalene formaldehyde condensate sulfonate, 5% antifreeze propylene glycol , thickener xanthan gum 0.2%, preservative sodium benzoate 0.2%, water to make up to 100%.

[0037] 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

[0039] 75%WDG

[0040] The formula is composed of: 45% of active ingredient A, 30% of active ingredient B, 5% of wetting agent phenethylphenol polyoxyethylene ether, 6% of dispersant sodium lignosulfonate, 3% of polycarboxylate dispersant %, filler kaolin makes up to 100%.

[0041] The preparation method is as follows: after mixing all the materials evenly, pulverize them with a jet mill, and mix evenly again, then add a certain amount of water to knead the mixture, extrude and granulate, dry and sieve to obtain the water dispersible granule.

Abstract

The invention belongs to the technical field of herbicides, and in particular relates to a fluridone compound herbicide. The fluridone compound herbicide comprises active components A and B. The active component A is fluridone and the active component B is selected from one or two of pyroxasulfone and oxyfluorfen. The fluridone compound herbicide has the beneficial effects that 1, a blended composition has a good synergistic effect, the application effect is obviously superior to the sum of single theatrical effects, that is, the blended composition has a superimposing effect, and damage of advantageous weeds can be controlled better; 2, the active components of the blended composition has good complementarity in weed control spectrum, can expand the weed control spectrum better, and controls various weed damages comprehensively and effectively; and 3, the blended composition has the good synergistic effect, so that the dosage of an agent can be reduced, the using cost and the environmental pollution can be reduced and the safety of crops can be improved.

Description

technical field [0001] The invention belongs to the technical field of herbicides, and in particular relates to a compound herbicide of chlorpyrizone and a preparation method thereof. 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. The single-dose varieties of oxyfluorfen, oxadiazone, acetochlor, etc. currently on the market have been used for a long time, and many weeds have developed resistance, and the dosage is high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a chlorpyrizone compound herbicide that is s...
