Problems solved by technology

[0002] In the prior art, quinclorac is mainly processed into wettable powder. Due to the limitation of processing technology, the fineness of the preparation is relatively coarse; at the same time, due to the limitation of formula composition, the spreading, penetration and systemic conduction of the agent on the weed leaves are poor. make it less effective

preparation example Construction

[0036] The present invention provides a kind of preparation method of quinclorac oil suspension concentrate herbicide described in above-mentioned technical scheme, comprises the following steps:

[0037] 1%~30% of quinclorac, 10~20% of emulsifier, 1~3% of dispersant, 10~20% of compound synergist, 0.5~3.0% of organic bentonite, 0.1~0.5% of defoamer and the rest Measure methyl oleate and mix evenly, sand mill until the material fineness reaches D 98 Be about 5 microns, obtain quinclorac oil suspension herbicide.

[0038] In the present invention, the sanding time is 2-3 hours. Grinding until the material fineness reaches D 98 6.5 microns, 5.7 microns, 4.5 microns, 6 microns or 5 microns.

[0039] Application of the herbicide described in the above technical scheme or the quinclorac oil suspension herbicide prepared by the preparation method described in the above technical scheme in controlling barnyardgrass in paddy fields.

[0040] In the present invention, the herbicide ...

Embodiment 1

[0046] Weigh 53.9 grams of methyl oleate as the dispersion medium and add it to a reaction kettle with shearing and stirring functions, then add ethoxylated mixed fatty acid emulsifier VO / 02N: 15 grams, modified polycarboxylate dispersant 3472B- N: 3g, silicone synergist BH-100: 5g, nonionic synergist 1118: 10g, organic bentonite thickener OF-102: 1.0g, silicone defoamer DF-1398 : 0.2 grams, 11.9 grams of the original drug of quinclorac (content 83.9%), open shearing and stirring and mixing for 10 minutes, until the various materials are mixed evenly, the materials after mixing are added to the sand mill, and after sand milling for 2 hours , the detection material fineness reaches D 98 After 5 microns, filter the discharge, detect according to the quality standard of oil suspension, after the quality is qualified, obtain 10% quinclorac oil suspension.

Embodiment 2

[0048] Weigh 57.4 grams of methyl oleate as the dispersion medium and add it to a reaction kettle with shearing and stirring functions, then add phenethylphenol polyoxyethylene emulsifier OD18: 12 grams, modified polycarboxylate dispersant 3472B- N: 3 grams, fatty alcohol polyoxyethylene synergist NP-10: 5 grams, non-ionic synergist 1118: 10 grams, organic bentonite thickener OF-102: 0.5 grams, silicone defoamer DF-1398: 0.2 grams, 11.9 grams of quinclorac (content 83.9%), start shearing and stirring for 5 minutes, until all materials are mixed evenly, put the mixed materials into the sand mill, sand mill After 2 hours, the detection material fineness reaches D 98 : after 6.5 microns, filter the discharge, detect according to the quality standard of oil suspension, after the quality is qualified, obtain 10% quinclorac oil suspension.

Abstract

The invention provides a preparation method and application of a quinclorac oil suspension herbicide. The herbicide consists of the following components in terms of mass fraction: 1% to 30% of quinclorac, 10 to 20% of an emulsifier, Dispersant 1-3%, composite synergist 10-20%, thickener 0.5-3.0%, defoamer 0.1-0.5%, and the balance is methyl oleate. Compared with the wettable powder of quinclorac, the present invention adopts the oil suspension of quinclorac, and under the joint action of the above-mentioned components, it can prevent and control barnyard grass in paddy fields, and the drug effect is fast, and it is safe for rice. .

Description

technical field [0001] The invention belongs to the technical field of herbicides, and in particular relates to a quinclorac oil suspension herbicide, a preparation method and application thereof. Background technique [0002] In the prior art, quinclorac is mainly processed into wettable powder. Due to the limitation of processing technology, the fineness of the preparation is relatively coarse; at the same time, due to the limitation of formula composition, the spreading, penetration and systemic conduction of the agent on the weed leaves are poor. make it less effective. Contents of the invention [0003] In view of this, the object of the present invention is to provide a kind of quinclorac oil suspension herbicide, its preparation method and application thereof, and this quinclorac oil suspension herbicide has better herbicidal effect. [0004] The invention provides a quinclorac oil suspension concentrate herbicide, which consists of the following components in term...
