The invention discloses a kind of tribenuron-methyl and the compound method of cloransulammethyl microemulsion, the method belongs to herbicide production field, the method is with tribenuron-methyl water dispersible granule 13-14%, cloransulammethyl 3-4%, isobutanol 18%, methyl naphthalene sulfonic acid sodium 5%, water 60% as raw material, tribenuron-methyl and cloransulammethyl microemulsion are produced by the method for secondary blending, the advantage of the production method is：Process is simple, environmental pollution is small, the reaction time is short, reaction condition is gentle, tribenuron-methyl and cloransulammethyl compounding have synergistic effect, after above-mentioned two kinds of herbicides and auxiliary material compounding, the effect is significant of anti-weeding is higher than alone tribenuron-methyl or cloransulammethyl, herbicidal effect is greatly enhanced, and the kind of herbicide further increases.
Description
Technical field
The invention belongs to herbicide field, more particularly to a kind of tribenuron-methyl and cloransulammethyl microemulsion compound method.
Background technology
Tribenuron-methyl, it is quiet also known as broad-leaved, water and organic solvent are slightly soluble in, common formulations are 10% tribenuron-methyl wettable powder, 75% tribenuron-methyl water dispersible granule.Tribenuron-methyl is selective inner-adsorption conduction-type herbicide,Can be by the root of weeds,Leaf absorbs,And conducted in plant body,By the activity for suppressing acetolactate synthestase,So as to influence the biosynthesis of branched-chain amino acid,Growing point necrosis is shown as after hazard of plant,Vein chlorosis,Plant growth is heavily suppressed,Downgrade,Final complete stool is withered,Susceptible weeds stop growing immediately after absorbing medicament,It is dead after 1-3 weeks,Applicable crops are wheat,Barley,Highland barley,Oat,Prevent and kill off object and be mainly various annual broadleaf weeds,To Descurainia sophia,Shepherd's purse,Crack rice shepherd's purse,Corn gromwell,Lamb's-quarters,Amaranthus retroflexus and other effects is preferably,To summer cypress,Chickweed,Knotweed,Clearvers etc. also has certain preventive effect,To creeping thistle,Volume stem smartweed,Field bindweed,Wartwort and other effects is not notable,To wild oat,Amur foxtail,Bromegrass,The grassy weeds such as Triticum tauschii are invalid.Cloransulammethyl, molecular formula is C14H11CIFN5O5S, and outward appearance is pale solid, 216~218 DEG C of fusing point, and solubility is 184 mg/litres in water at 20 DEG C, and low toxicity, without teratogenesis, carcinogenic, mutagenesis, also has no adverse effects to heredity；Weeding principle is：The medicine belongs to inner-adsorption conduction-type herbicide, weeds root system and stem, leaf can absorb medicament, conducted upwards, downwards by xylem and bast, finally it is accumulated in plant meristem, causes weeds vivo protein biosynthesis block, growth retardation, it is dead, the existing cauline leaf process effect of the medicine, also there is soil sealing effect, and good to the security of crop；It is mainly used in Soybean Field and prevents and kill off broad leaved weed such as piemarker, artemisiifolia, great ragweed, Siberian cocklebur, pharbitis nilChoisy, amaranth, knotweed, lamb's-quarters, dayflower, lettuce pod dish etc..Tribenuron-methyl and cloransulammethyl compounding have synergistic effect, and after above-mentioned two kinds of herbicides and auxiliary material compounding, higher than alone tribenuron-methyl or cloransulammethyl, herbicidal effect is greatly enhanced the effect is significant of anti-weeding, and the kind of herbicide further increases.
The content of the invention
Present invention mainly solves problem be to provide the compound method of a kind of tribenuron-methyl and cloransulammethyl microemulsion, produce the raw material that the product uses is by weight ratio：Tribenuron-methyl water dispersible granule 13-14%, cloransulammethyl 3-4%, isobutanol 18%, methyl naphthalene sulfonic acid sodium 5%, water 60%.
The technical solution adopted by the present invention is：
（1）First the isobutanol of formula ratio is added in the first agitator tank, stirring is started under normal temperature, cloransulammethyl, the methyl naphthalene sulfonic acid sodium of formula ratio, stirring reaction 0.4-0.5 hours are added while stirring；
（2）First the water of formula ratio is added in high-speed stirred tank, stirring is started under normal temperature, the rotating speed of agitator is 30-40 revs/min, and the tribenuron-methyl water dispersible granule of formula ratio is added while stirring；The rotating speed for heightening agitator in fast agitator tank is 210-220
Rev/min, the mixture of isobutanol, cloransulammethyl, methyl naphthalene sulfonic acid sodium is slowly added into high-speed stirred tank, obtain finished product after stirring reaction 0.9-1.0 hours.
Further technical scheme of the invention is：
The purity of described tribenuron-methyl water dispersible granule is that the purity of 75%, cloransulammethyl is 60%.
Step（1）, step（2）Described normal temperature is 0-38 DEG C.
The beneficial effects of the invention are as follows：There is provided a kind of tribenuron-methyl and the compound method of cloransulammethyl microemulsion, the advantage of the production method is：Process is simple, environmental pollution is small, the reaction time is short, reaction condition is gentle, tribenuron-methyl and cloransulammethyl compounding have synergistic effect, after above-mentioned two kinds of herbicides and auxiliary material compounding, the effect is significant of anti-weeding is higher than alone tribenuron-methyl and cloransulammethyl, herbicidal effect is greatly enhanced, and the kind of herbicide further increases.
