Description
Technical field
The invention belongs to herbicide field, more particularly to a kind of tribenuron-methyl and chlortoluron 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.Chlortoluron is a kind of selective inner sucting conduction type carbamide herbicides,Sterling is crystallized for no color or smell,Former powder is yellowish-brown blocks of solid,It is insoluble in water,Stablize at normal temperatures,Nonflammable and blast,Non-corrosiveness,Meet highly basic strong acid decomposable asymmetric choice net,To birds and fish low toxicity,It is nontoxic to honeybee,The main Root Absorption by weeds,And have blade face action of contace poison,Make weeds photosynthesis electron transfer inhibitor,Make weeds hungry and dead,3 days after dispenser,Weeds start to show poisoning symptom,Blade chlorisis,Blade tip and the successive chlorosis of lobus cardiacus,Whole strain in about 10 days or so is withered and dead,More than 70 days lasting period in soil,It is mainly used in wheat,Barley,Corn,Sorghum,Cotton,Peanut,Soybean,Tobacco,Amur foxtail is prevented and treated in the dry crops such as highland barley,Annual bluegrass,Wild oat,Chickweed,Ox chickweed,Tongue of sparrow grass,Green bristlegrass,Lady's-grass,Descurainia sophia,Centipeda minima,Bur beggar-ticks,Pale persicaria,Willow leaf thorn smartweed,Barnyard grass,Amaranth,Acalypha copperleaf,Purslane
, Trigonotis peduncularis, lamb's-quarters, Siberian cocklebur, annual gramineae, Cyperaceae and most of broad leaved weeds such as Veronica, also have some effects to caput grass, hard grass.Tribenuron-methyl and chlortoluron compounding have synergistic effect, and after above-mentioned two kinds of herbicides and auxiliary material compounding, higher than alone tribenuron-methyl or chlortoluron, 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 chlortoluron microemulsion, produce the raw material that the product uses is by weight ratio：Tribenuron-methyl water dispersible granule 12-13%, chlortoluron wettable powder 4-5%, fatty alcohol ethylene oxide adduct sodium sulfonate 4%, ethanol 12%, water 67%.
The technical solution adopted by the present invention is：
（1）First the ethanol of formula ratio is added in the first agitator tank, stirring is started under normal temperature, the chlortoluron wettable powder of formula ratio, stirring reaction 0.3-0.4 hours are added while stirring；
（2）First the water of formula ratio is added in high-speed stirred tank, start stirring under normal temperature, the rotating speed of agitator is 30-40 revs/min, add the fatty alcohol ethylene oxide adduct sodium sulfonate of formula ratio, stirring to fatty alcohol ethylene oxide adduct sodium sulfonate that the tribenuron-methyl water dispersible granule of formula ratio is added after all dissolving while stirring；The rotating speed of agitator in fast agitator tank is heightened for 210-220 revs/min, the chlortoluron wettable powder that will slowly be dissolved in ethanol adds high-speed stirred tank, and finished product is obtained 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%, chlortoluron wettable powder is 45%.
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 chlortoluron microemulsion, the advantage of the production method is：Process is simple, environmental pollution is small, the reaction time is short, reaction condition is gentle, benzene tribenuron-methyl and chlortoluron 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 chlortoluron, herbicidal effect is greatly enhanced, and the kind of herbicide further increases.
