Abstract
The present invention provides a pinoxaden-compounded water dispersible granule, which comprises the following raw materials in weight percentage: 20-30% of pinoxaden, 5-10% of florasulam, 2-10% of wetting agent, 2-8% of dispersant, 3-6% of betaine, 0.5-6% of binder and fillings as the balance. The binder is a mixture of starch and fumed silica. The water dispersible granule is good in dispersibility and suspendability, and the weeding spectrum of the water dispersible granule is expanded. Therefore, the water dispersible granule is capable of effectively preventing and killing off broad-leaved weeds and grassy weeds in a wheat paddock.
Description
Technical field
The invention belongs to herbicide technology field is and in particular to a kind of pinoxaden compound water dispersible granule.
Background technology
Pinoxaden (pinoxaden) belongs to neophyl pyrazolines herbicide, molecular formula：C23H32N24, chemical name：8-
(2,6- diethyl -4- aminomethyl phenyl) -1,2,4,5- tetrahydrochysene -7- oxygen -7H- pyrazoles [1,2-d] [1,4,5] oxygen phenodiazine Zhuo -9- base
2,2- dimethyl propylene acid esters.Pinoxaden is acetyl-CoA carboxylase inhibitor, causes aliphatic acid biosynthesis block, so that cell is given birth to
Long division stops, and cell membrane is destructurized containing fat, leads to weeds dead.This herbicide be mainly used in barley field prevent and kill off annual
Grassy weed, has good preventive effect to wild oat, hard grass, grass, amur foxtail etc..After general dispenser, 48 hours susceptible weeds are stopped
Only grow, in 1～2 week, grass cutting blade starts to turn to be yellow, and in 3～4 weeks, weeds are thoroughly dead.Safe to barley, in bad gas
(low temperature or high humidity) dispenser under the conditions of time, barley leaves are it is possible that temporary transient chlorosis symptom, but do not affect its normal growth
Develop and ultimate output.
Florasulam is by the triazolopyrimidine sulfonamides herbicide of LG-DOW agricultural sciences company exploitation.20 generation
Record the LG-DOW agricultural sciences company reported first pyrimidine acetamide-group herbicides eighties, successfully develop thereafter multiple with three
Azoles pyrimidine sulphonamide are the highy potent herbicide new varieties of parent compound.Florasulam is continue metosulam, flumetsulam
The 5th triazolopyrimidine succeeded in developing after the mid-90 in 20th century of amine, cloransulammethyl and diclosulam
Class herbicide new varieties.Application crop：It is mainly used in winter wheat field and prevent and kill off broad leaved weed.
Existing market has no the water dispersible granules development report that herbicide florasulam is compounded with pinoxaden.
Content of the invention
The present invention proposes a kind of pinoxaden compound water dispersible granule, and this water dispersible granules not only disperses suspendability good,
And expand weed control spectrum, can effectively prevent and kill off the broad leaved weed of wheat paddock and to grassy weed.
The technical scheme is that and be achieved in that：
A kind of pinoxaden compound water dispersible granule, calculates according to percetage by weight, including：
Pinoxaden 20～30%, florasulam 5～10%, wetting agent 2～10%, dispersant 2～8%, glycine betaine 3
～6%, adhesive 0.5～6%, balance of filler；Described adhesive is starch and aerosil mixture, described oxazoline
Careless ester is washed with 0.1～0.5wt% sodium bicarbonate solution in advance.
Further, described starch 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 glycine betaine is N- lauroyl amido glycine betaine, N- palmityl amido glycine betaine, N- stearamide base
Glycine betaine, dodecyl azochlorosulfonate propyl lycine or cocamidopropyl propyl amide sulfobetaines.
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 pinoxaden compound water dispersible granule of the present invention：
By formula, pinoxaden active compound, florasulam, wetting agent, dispersant, glycine betaine, adhesive and filler are filled
Point mixing, through coarse crushing, remix, airslide disintegrating mill is pulverized, and enters into cone-type mixer mixing, accurate by 300～400 targets
Sieve to obtain fine powder, afterwards, add water in fine powder kneading, extruder grain, compound moisture in 40 DEG C～60 DEG C drying pinoxaden
Shot agent.
Beneficial effects of the present invention：
1st, after adding glycine betaine spraying in the water dispersible granules of the present invention, there is low surface tension, in target surface wetting
Property good, sprawl strong with penetrating power, target surface be distributed in fine particle, be conducive to improving drug effect.Organosilicon auxiliary agent can make
Liquid reaches the place being difficult to soak, and increases spray coverage, promotes liquid quickly to absorb.Improve the resistance of rainwater washing against energy of liquid
Power, improves the effective rate of utilization of agricultural chemicals, reduces agricultural chemicals injected volume.Adhesive is enhanced with aerosil mixture for starch
Gel space network structure, improves its thixotropic property, has improve water dispersible granules stability.
2nd, opening up good penetrability as object plane when the pinoxaden compound water dispersible granule of the present invention uses, decreasing effectively
Ingredients from lossing, has notable synergistic to act on.Original suspension rate >=96%；Suspensibility >=90% after 54 ± 2 heat storages 30 days；Disintegration time
≤60s；Wetting time≤50s；Persistent foamability (after 1min)≤10ml.
3rd, the pinoxaden compound water dispersible granule of the present invention expand weed control spectrum, the broad-leaved that can effectively prevent and kill off wheat paddock miscellaneous
Grass and to grassy weed.
