Abstract
The invention discloses a kind of tribenuron-methyl and benthiocarb microemulsion, which belongs to herbicide production field, and prepare the raw material that the product uses includes by weight ratio：The advantages of tribenuron-methyl water dispersible granule 7 8%, benthiocarb 7 8%, ethyl alcohol 15%, sodium alkyl sulfate 2%, water 68%, tribenuron-methyl and benthiocarb microemulsion are produced by the method for secondary blending, the production method be：It is simple for process, environmental pollution is small, the reaction time is short, reaction condition is mild, tribenuron-methyl and benthiocarb compounding have synergistic effect, after above-mentioned two kinds of herbicides and auxiliary material compounding, the significant effect of anti-weeding, which is higher than, is applied alone tribenuron-methyl or benthiocarb, herbicidal effect greatly enhances, and the kind of herbicide further increases.
Description
Technical field
The invention belongs to herbicide field more particularly to the preparation methods of a kind of tribenuron-methyl and benthiocarb microemulsion.
Background technology
Tribenuron-methyl, also known as broad-leaved is quiet, is slightly soluble in water and organic solvent, is selective inner-adsorption conduction-type herbicide, can be miscellaneous
Root, the leaf of grass are absorbed, and conducted in plant body, by inhibiting the activity of acetolactate synthestase, so as to influence branched-amino
The biosynthesis of acid shows as growing point necrosis, vein chlorosis after hazard of plant, and plant growth is heavily suppressed, downgrades, most
Whole complete stool is withered, and susceptible weeds stop growing immediately after absorbing medicament, and dead after 1-3 weeks, control object is mainly various 1 years
Raw broad leaved weed.Benthiocarb also known as weed eradication are red, and appearance is weak yellow liquid, is dissolved in most organic solvents, in acid, alkaline condition
Lower stabilization, benthiocarb are broad-spectrum herbicide, have special efficacy to rice terrace fescue, barnyard grass, can effectively prevent and kill off Monochoria vaginalis, Sagittaria pygmaea etc.
Annual grassy weeds, to crop safeties such as rice, wheat, rape, peanut, soybean, cotton, corn, sugarcanes.Tribenuron-methyl and benthiocarb
Compounding has synergistic effect, will after above-mentioned two kinds of herbicides and auxiliary material compounding, the significant effect of anti-weeding be higher than be applied alone tribenuron-methyl or
Benthiocarb, herbicidal effect greatly enhance, and the kind of herbicide further increases.
The content of the invention
Present invention mainly solves the problem of be to provide a kind of tribenuron-methyl and benthiocarb microemulsion, prepare the original that the product uses
Material be by weight ratio：Tribenuron-methyl water dispersible granule 7-8%, benthiocarb 7-8%, ethyl alcohol 15%, sodium alkyl sulfate 2%, water 68%.
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
Benthiocarb and sodium alkyl sulfate, 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 20-25/
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 ethyl alcohol, benthiocarb and sodium alkyl sulfate 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 benthiocarb is 80%.
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 benthiocarb microemulsion are provided, the advantages of preparation method is：
It is simple for process, environmental pollution is small, the reaction time is short, reaction condition is mild, tribenuron-methyl and benthiocarb compounding have synergistic effect, will be upper
After stating two kinds of herbicides and auxiliary material compounding, the significant effect of anti-weeding is higher than tribenuron-methyl or benthiocarb is applied alone, and herbicidal effect is significantly
Enhancing, the kind of herbicide further increase.
