Abstract
The invention provides metribuzin water dispersible granules. The granules are prepared from, by weight, 20-50% of metribuzin, 2-10 parts of a wetting agent, 2-8% of a dispersing agent, 3-6% of an organosilicon surfactant, 0.5-6% of an adhesive and the balance filler. The adhesive is a mixture of starch and fumed silica. The water dispersible granules are good in dispersibility and good in medicine effect.
Description
Technical field
The invention belongs to herbicide technology field is and in particular to a kind of metribuzin water dispersible granules.
Background technology
Metribuzin (4- amino -6- tertiary butyl -4,5- dihydro -3- methyl mercapto -1,2,4- triazine -5 (4h) -one, mtb) is choosing
Selecting property herbicide, its effective ingredient is absorbed by weeds root system and conducts to top with transpiration current, also can be absorbed by blade and make in vivo
Limited conduction, the main photosynthesis passing through to suppress sensitive plant plays removing activity, and after dispenser, each susceptible weeds are sprouted
Seedling is unaffected, rear blade chlorisis of emerging, and last nutrition is exhausted and dead.Metribuzin be widely used as preventing and kill off soybean, potato, kind
Eggplant and the herbicide of other crop before seedlings and after seedling weeds, can effectively prevent and treat potato fields Siberian cocklebur, lamb's-quarters, the weeds such as green bristlegrass.
Pesticide water dispersible granules be insoluble in the solid pesticide active compound of water and wetting agent, dispersant, other function additive and
Filler after sufficiently mixing, is ground into trickle powdery solid, then through mediating, granulation, be dried, the sieve operation such as part is formed
Can be disintegrated rapidly in water for primary granule size the formulations of pesticide that are dispersed into stable suspension.Water dispersible granules are not only solvent-free
And dust, to operator's safety, and decrease the pollution to environment.On existing market, the formulation of metribuzin is mainly wettable
Pulvis, its water dispersible granules leads to effect poor due to suspensibility difference, and peasant is using dissatisfied.
Content of the invention
The present invention proposes a kind of metribuzin water dispersible granules, and not only dispersive property is good for this water dispersible granules, and good drug efficacy.
The technical scheme is that and be achieved in that:
A kind of metribuzin water dispersible granules, calculate according to percetage by weight, comprising:
Metribuzin 20～50%, wetting agent 2～10%, dispersant 2～8%, organic silicon surfactant 3～6%, cohere
Agent 0.5～6%, balance of filler；Described adhesive is starch and aerosil mixture.
Further, described starch and the mass ratio of aerosil are 6～8:1.
Further, described wetting agent is fatty alcohol polyglycol ether sulfate, AEO or alkylnaphthalene
Sulfonic formaldehyde condensation compound.
Further, described dispersant is selected from sodium lignin sulfonate, calcium lignosulfonate, sodium methylene bis-naphthalene sulfonate or gathers
Vinylpyrrolidone.
Further, described organic silicon surfactant is organic silicon surfactant silwet408.
Further, described filler is selected from one of kaolin, diatomite, bentonite, precipitated calcium carbonate and ammonium sulfate
Or it is several.
The preparation method of metribuzin of the present invention:
Will be abundant to metribuzin active compound, wetting agent, dispersant, organic silicon surfactant, adhesive and filler by formula
Mixing, through coarse crushing, remix, airslide disintegrating mill pulverize, enter into cone-type mixer mixing, by 300～400 mesh standard sieves
Obtain fine powder, afterwards, add water in fine powder kneading, extruder grain, in 40 DEG C～60 DEG C drying metribuzin water dispersible granules.
Beneficial effects of the present invention:
1st, there is low surface tension, in target after adding organic silicon surfactant spraying in the water dispersible granules of the present invention
Mark surface wettability is good, sprawls strong with penetrating power, is distributed in target surface with fine particle, is conducive to improving drug effect.Organic
Silicon additive can make liquid reach the place being difficult to soak, and increases spray coverage, promotes liquid quickly to absorb.Improve the resistance to of liquid
Rain drop erosion ability, improves the effective rate of utilization of agricultural chemicals, reduces agricultural chemicals injected volume.Adhesive is that starch is mixed with aerosil
Compound enhances gel space network structure, improves its thixotropic property, has improve water dispersible granules stability.
2nd, the metribuzin water dispersible granules of the present invention are opening up good penetrability as object plane when using, and decrease active ingredient stream
Lose, have notable synergistic to act on.Original suspension rate >=97%；Suspensibility >=90% after 54 ± 2 heat storages 30 days；Disintegration time≤60s；
Wetting time 60s；Persistent foamability (after 1min)≤20ml.
