Abstract
The invention provides a metamifop water dispersible granule. The granule is prepared from, by weight, 10-30% of metamifop, 2-10% of wetting agent, 2-8% of dispersing agent, 3-6% of organosilicone surface active agent, 0.5-6% of adhesive and the balance filler. The adhesive is a mixture of corn starch and gas-phase silicon dioxide. Metamifop is washed through a sodium bicarbonate solution with concentration of 0.1-0.5 wt% in advance. The water dispersible granule is high in suspension stability, meets the requirements of high-altitude low-temperature regions, and reduces the influences of organic solvent on the environment.
Description
Technical field
The invention belongs to herbicide technology field is and in particular to a kind of azole amide water dispersible granules.
Background technology
Azole amide (English name metamifop) is by the novel herbicide of Chemical Engineering Technology institute of Korea S exploitation, belongs to fragrant oxygen benzene
Epoxide propionic acid ester herbicide, can be fabulous prevent and kill off most of annual gramineous weeds, and from unlike such herbicide
Azole amide is safe to paddy rice.Azole amide is in after seedling with 90-200g/hm2Spray in the case of effective ingredient consumption
Impose on transplanting and direct seading rice field, can effectively prevent and kill off main weeds in rice field, such as Echinochloa, moleplant seed, knotgrass and eleusine indica.Thousand
Gold is one of the malignant weed in rice field, has that generation is wide, and the big feature of generating capacity simultaneously has the trend that harm increases.1996～
General survey of rice field weeds result shows within 1999: moleplant seed hazard index has been risen to 7.10 in 1999 by the 1.81 of nineteen ninety-five,
Occurrence frequency is risen to 19.5% in 1999 by 5.7% in 1999.In recent years with planting patterns and single variety weeding
The use of agent, makes moleplant seed have gone up main malignant weed for rice field, harm is increasingly severe, in the harm journey in part rice field
Degree exceed barnyard grass, particularly in direct sowing rice field, the underproduction 30-40% during serious harm, can be caused, have up to more than 70%, or even
Total crop failure, it is vigorous that Chang Yin broadcasts rear moleplant seed, and peasant household has to replay of turning over.
Water dispersible granules also known as solid carbon dioxide dispersible granule or grain type wettable powder, once putting in water, can be disintegrated quickly,
Dispersion, forms the granular preparation of the solid-liquid dispersing system of higher suspension.Water-dispersible granules except have the characteristics that general granula it
Outward, also show several features as follows: (1) does not have dust from flying, reduce the pollution to environment, to operator's safety, and
And toxic articles kind low toxicity can be made；(2) compared with wettable powder and water dispersible granules, active constituent content is high, product phase
Big to density, small volume, it is easy to packaging, storage and transport；(3) bin stability and physical and chemical stability are preferable, particularly
To unstable agricultural chemicals in water, make this formulation better than water dispersible granules；(4) disintegration rate of particle is fast, and particle one touches
Water can be wet immediately, and is disintegrated rapidly during sinking under the water；(5), after particle is disintegrated in water, disperse poling quickly
Little particulate, after disintegration agitation, through 325 mesh wet sievings, on sieve, residue is not more than 0.3%；(6) suspension stability is preferable,
The liquid same day preparing is not finished, and agitated energy Eddy diffusion gets up within second day, does not affect drug effect；(7) disperse in a liquid
Particle only need to slightly stir tiny particulate and can be well dispersed in liquid, uniformity can be kept until liquid medicine jet is complete.
Existing azole amide with oil suspend and missible oil based on although water dispersible granules can be processed into, due to its disperse suspension
Stabilizability can be poor, leads to it to use and is restricted.
Content of the invention
The present invention proposes a kind of azole amide water dispersible granules, and this water dispersible granules not only disperses suspendability good, also
Decrease the impact to environment for the organic solvent.
The technical scheme is that and be achieved in that:
A kind of azole amide water dispersible granules, calculate according to percetage by weight, comprising:
Azole amide 10～30%, wetting agent 2～10%, dispersant 2～8%, organic silicon surfactant 3～6%,
Adhesive 0.5～6%, balance of filler；Described adhesive is cornstarch and aerosil mixture, described azoles acyl
Careless amine is washed with 0.1～0.5wt% sodium bicarbonate solution in advance.
Further, described cornstarch and the mass ratio of aerosil are 6～8:1.
Further, described wetting agent is lauryl sodium sulfate, lignin, spaonin powder or APES.
Further, described dispersant be selected from sodium lignin sulfonate, calcium lignosulfonate, sodium methylene bis-naphthalene sulfonate or
morwet-450.
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 azole amide water dispersible granules of the present invention:
Azole amide active compound is stirred with 0.1～0.5wt% sodium bicarbonate solution washing by soaking, filtering drying standby
With；And fill out the azole amide active compound after drying, wetting agent, dispersant, organic silicon surfactant, adhesive by formula
Material is sufficiently mixed, through coarse crushing, remix, airslide disintegrating mill is pulverized, and enters into cone-type mixer mixing, accurate by 325 targets
Sieve to obtain fine powder, afterwards, add water in fine powder kneading, extruder grain, dissipate in 40 DEG C～60 DEG C drying azole amide moisture
Granula.
Inventor is it was unexpectedly observed that use the particle water of the azole amide active compound preparation processing through sodium bicarbonate solution
Dispersible granule, with the particle water dispersible granule phase using the azole amide active compound preparation processing without sodium bicarbonate solution
All increase significantly than, its suspensibility and stability, what this was likely due to contain in azole amide active compound remains in it
In acid impurities water dispersible granules can be adversely affected, and can effectively eliminate this impact through simple alkali process.
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 cornstarch and gas phase titanium dioxide
Silicon mixture enhances gel space network structure, improves its thixotropic property, has improve water dispersible granules stability.
2nd, the Sulfonylurea compound water dispersible granule of the present invention is opening up good penetrability as object plane when using, and has decreased
Effect ingredients from lossing, has notable synergistic to act on.Original suspension rate >=98%；Suspensibility >=91% after 54 ± 2 heat storages 30 days；During disintegration
Between≤50s；Wetting time 45s；Persistent foamability (after 1min)≤20ml.The azole amide water dispersible granules of the present invention reduce
The use of organic solvent, more environmentally friendly, safety, store and transport and use safety, and environmentally friendly, meet sending out of the current formulations of pesticide
Exhibition direction.
