Abstract
The invention discloses a kind of tribenuron-methyl and pretilachlor microemulsion, which belongs to herbicide field；Preparing the raw material that the product uses includes：Tribenuron-methyl water dispersible granule 11 12%, pretilachlor 4 5%, styrene 12%, phenylcyclohexanone 2%, water 70%, 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 pretilachlor compounding have synergistic effect, after above-mentioned two kinds of herbicides and auxiliary material compounding, prevent and kill off the significant effect of paddy field weed higher than tribenuron-methyl or pretilachlor is applied alone, herbicidal effect greatly enhances, also available for dry land.
Description
Technical field
The invention belongs to herbicide field more particularly to the preparation methods of a kind of tribenuron-methyl and pretilachlor 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.Pretilachlor, also known as ten safeners, are selective herbicides before the bud of amides rice field, can be safely used for live streaming field
And rice seedling bed, to a leaf wholeheartedly within barnyard grass preventive effect up to more than 95%, safe due to it, user can reduce sowing
Amount saves seed spending, while reduces the sandwich barnyard grass to rice underproduction maximum, and reliable basis has been laid for increasing production of rice；
Pretilachlor to weeds gramineous in addition to having good preventive effect, moreover it is possible to prevent and kill off a variety of annual nutgrass flatsedges and broadleaf weed, holding effect
30-50 days phase can control nursery period overall process weeds substantially, and easy to use, be sprayed on after can directly diluting with sprayer
On seedling bed, fine earth can also be mixed, is spread on seedling face.Tribenuron-methyl has synergistic effect with pretilachlor compounding, by above-mentioned two kinds of herbicides
After being compounded with auxiliary material, the significant effect of paddy field weed is prevented and kill off higher than tribenuron-methyl or pretilachlor is applied alone, herbicidal effect greatly enhances.
The content of the invention
Present invention mainly solves the problem of be to provide a kind of tribenuron-methyl and pretilachlor microemulsion, prepare the original that the product uses
Material be by weight ratio：Tribenuron-methyl water dispersible granule 11-12%, pretilachlor 4-5%, styrene 12%, phenylcyclohexanone 2%, water 70%.
The technical solution adopted by the present invention is：
（1）First the styrene of formula ratio is added in the first agitator tank, starts to stir under room temperature, adds in formula ratio while stirring
Pretilachlor, phenylcyclohexanone, be stirred to react 0.6-0.7 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 styrene, pretilachlor, phenylcyclohexanone is slowly added in into high-speed stirred tank, it is small to be stirred to react 0.4-0.5
When after obtain finished product.
The present invention further technical solution be：
The purity of the tribenuron-methyl water dispersible granule is 75%, the purity of pretilachlor is 25%.
Step（1）, step（2）The room temperature is 0-38 DEG C.
The beneficial effects of the invention are as follows：A kind of tribenuron-methyl and pretilachlor 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 pretilachlor compounding have synergistic effect, will be upper
After stating two kinds of herbicides and auxiliary material compounding, for the significant effect of management of weeds higher than tribenuron-methyl or pretilachlor is applied alone, herbicidal effect is big
Big enhancing, is applicable to paddy field, also available for dry land.
