Abstract
The invention discloses a kind of tribenuron-methyl and cyhalofop-butyl microemulsion, which belongs to herbicide field；Prepare the raw material that the product uses includes by weight ratio：Tribenuron-methyl water dispersible granule 8 9%, cyhalofop-butyl 6 7%, ethyl alcohol 16%, sodium alkyl sulfonate 2%, water 67%, by blending finished product under given conditions, the advantages of production method, is：Using common apparatus, simple for process, reaction condition is mild, pollution-free waste discharge；Tribenuron-methyl and cyhalofop-butyl compounding have a synergistic effect, and higher than tribenuron-methyl or cyhalofop-butyl is applied alone, herbicidal effect greatly enhances the significant effect of anti-weeding, available for preventing and kill off broad leaved weed and annual, perennial grassy weed.
Description
Technical field
The invention belongs to herbicide field more particularly to the preparation methods of a kind of tribenuron-methyl and cyhalofop-butyl microemulsion.
Background technology
It is quiet that tribenuron-methyl is also known as broad-leaved, is slightly soluble in water and organic solvent, is selective inner-adsorption conduction-type herbicide, can be by weeds
Root, leaf absorb, and conducted in plant body, by inhibiting the activity of acetolactate synthestase, so as to influence branched-chain amino acid
Biosynthesis, growing point necrosis, vein chlorosis are shown as after hazard of plant, plant growth is heavily suppressed, downgrades, finally
Complete stool is withered, and susceptible weeds stop growing immediately after absorbing medicament, and dead after 1-3 weeks, control object is mainly various annual
Broad leaved weed.Cyhalofop-butyl category aryloxyphenoxypropionic class herbicide also known as a thousand pieces of gold, active compound appearance are white crystalline solid,
Most organic solvents are dissolved in, it is not soluble in water；Cyhalofop-butyl is uptake and translocation herbicide, is inhaled by the blade and leaf sheath of weeds
It receives, bast conduction accumulates the meristem zone in weeds, resists acetyl-CoA carboxylase, stops aliphatic acid synthesis, carefully
The growth division of born of the same parents cannot be normally carried out, and the structure containing fat such as membranous system is destroyed, and finally result in weeds death.Controlling object, to water
Rice is highly safe, efficient to above the average age for marriage barnyard grass to moleplant seed, barnyard grass special efficacy, while simultaneous anti-a variety of grassy weeds, cyhalofop-butyl exist
Degraded in soil is rapid, harmless to succession crop.After above-mentioned two kinds of herbicides and auxiliary material compounding, the significant effect of anti-weeding is high
In tribenuron-methyl or cyhalofop-butyl is applied alone, herbicidal effect greatly enhances, available for preventing and kill off broad leaved weed and annual, perennial grass
Section weeds.
The content of the invention
Present invention mainly solves the problem of be to provide a kind of tribenuron-methyl and cyhalofop-butyl microemulsion, prepare what the product used
Raw material is by weight ratio：Tribenuron-methyl water dispersible granule 8-9%, cyhalofop-butyl 6-7%, ethyl alcohol 16%, sodium alkyl sulfonate 2%, water
67%。
The technical solution adopted by the present invention is：
（1）First the ethyl alcohol of formula ratio is added in the first agitator tank, starts to stir under room temperature, adds in formula ratio while stirring
Cyhalofop-butyl, sodium alkyl sulfonate, be stirred to react 0.4-0.5 it is small when；
（2）First the water of formula ratio is added in high-speed stirred tank, starts to stir under room temperature, the rotating speed of blender turns for 20-30/
Divide, add in the tribenuron-methyl water dispersible granule of formula ratio while stirring；The rotating speed for heightening blender in fast agitator tank is 190-200
Rev/min, the mixture of cyhalofop-butyl, ethyl alcohol, sodium alkyl sulfonate is slowly added in into high-speed stirred tank, is stirred to react 0.4-0.5
Finished product is obtained after hour.
The present invention further technical solution be：
The purity of the tribenuron-methyl water dispersible granule is 75%, the purity of cyhalofop-butyl is 85%.
Step（1）, step（2）The room temperature is 2-35 DEG C.
The beneficial effects of the invention are as follows：A kind of tribenuron-methyl and cyhalofop-butyl microemulsion are provided, the advantages of the preparation method
It is：It is simple for process, environmental pollution is small, the reaction time is short, reaction condition is mild, tribenuron-methyl and cyhalofop-butyl compounding have synergy work
With higher than tribenuron-methyl or cyhalofop-butyl is applied alone, herbicidal effect greatly enhances the significant effect of anti-weeding, miscellaneous available for broad-leaved is prevented and kill off
Careless and annual, perennial grassy weed.
