Abstract
The invention discloses a kind of Wheat field weeding composition and its application, said composition is obtained by after the grass mixing of active component pinoxaden, isoproturon and double fluorine sulphurs；Also including one or more in emulsifying agent, wetting agent, dispersant, disintegrant, thickener, binding agent or defoamer as auxiliary agent, the formulation of composition is wettable powder, water dispersible granules, suspending agent or oil-suspending agent to said composition；Herbicidal combinations of the invention prevent and kill off wheat paddock annual grassy weeds effect and are substantially better than each single dose exclusive use and expand herbicide controlling spectrum, while reducing dosage, have delayed the generation of herbicide resistance.
Description
Technical field
The invention belongs to technical field of pesticide, and in particular to a kind of multiple containing pinoxaden, isoproturon and florasulam
The Herbicidal combinations matched somebody with somebody.
Background technology
Pinoxaden belongs to neophyl pyrazolines herbicide, and the mechanism of action is acetyl-CoA carboxylase (ACC) inhibitor.
Aliphatic acid biosynthesis block is caused, stops cell division, cell membrane is destructurized containing fat, cause weeds dead.Have
Uptake and translocation, grass cutting blade starts jaundice in 1~2 week after, and interior weeds are thoroughly dead within 3~4 weeks.It is currently used primarily in big
Wheatland prevents and kill off annual gramineous weed, miscellaneous to barley field annual gramineae through toxicity experiment and field control effectiveness test
Careless such as wild oat, green bristlegrass, barnyard grass has good preventive effect.But it is administered alone relatively costly, and it is not suitable for low application.
Isoproturon is substituted urea class selective herbicide.Its sterling is white crystals, is insoluble in water, and dissolving in most of has
Machine solvent, relatively stablizes to acid, alkali and light, is inner sucting conduction type processing soil treatment agent and cauline leaf process agent to people and animals' low toxicity.Medicament quilt
After plant root absorbs, teach and be accumulated in blade, suppress photosynthesis, cause weeds dead.It is usually used in preventing and kill off one at present
Year raw weeds, such as lady's-grass, lamb's-quarters, annual bluegrass, amur foxtail, it is adaptable to tomato, potato, nursery leek, sweet (peppery) green pepper, eggplant
Son, broad bean, pea, green onion first class sections vegetable farm herbicide.
Florasulam is that one kind is sulfonamides herbicide, and broad leaved weed is prevented and kill off for wheat paddock.Broad weed-killing spectrum, can prevent
Except the most of broad leaved weeds of wheatland, including the difficult anti-weeds such as clearvers, corn gromwell, and wartwort to being most difficult to prevent and kill off in wheatland has non-
Often good inhibitory action.Inner-adsorption conduction-type herbicide, can conduct to weeds complete stool, thus herbicide is thoroughly, will not recur.Low
Warm purgative effect stabilization, even still ensuring that stabilization drug effect at 2 DEG C.Also peanut, tobacco, clover and other feedings can effectively be prevented and kill off
Annual gramineous weed and broad leaved weed in material crop, 1.0~1.35kg/ha of consumption.
Rationally compounding is the speed for improving preventive effect, expanding herbicide controlling spectrum, delay shift of weed community to herbicide, and reduction makes
With cost and a kind of effective ways of reduction herbicide residue, pinoxaden, isoproturon and florasulam are not yet found at present
The relevant report of Herbicidal combination.
The content of the invention
It is an object of the invention to solve developed immunity to drugs to weeds of wheat in the prior art problem and actual preventing and treating effect
It is really poor, there is provided one kind is efficiently, low toxicity, quick-acting are good and the lasting period is long, are conducive to the weeding group of the weeds of wheat comprehensive regulation
Compound.
What the present invention was realized in：
A kind of Wheat field weeding composition, including active component, auxiliary agent and carrier, the active component by pinoxaden,
Isoproturon and florasulam, pinoxaden composition.
Further, in Wheat field weeding composition of the present invention, by weight percentage, pinoxaden accounts for 1%-
10%, isoproturon accounts for 25%~75%, and double fluorine sulphur grass account for 0.5%-2%.
Further, in Wheat field weeding composition of the present invention, the auxiliary agent be emulsifying agent, wetting agent, dispersant,
One or more in disintegrant, thickener, binding agent or defoamer.
Further, described Wheat field weeding composition, its formulation is with epoxidized soybean oil, methyl oleate, solvent naphtha, water
In it is a kind of be the suspending agent of carrier；
Or with a kind of water dispersible granules as carrier in diatomite, kaolin, fine particle calcium carbonate, cornstarch, ammonium sulfate；
Or with a kind of wettable powder as carrier in diatomite, kaolin, fine particle calcium carbonate, cornstarch, ammonium sulfate；
Or with a kind of granule as carrier in diatomite, kaolin, fine particle calcium carbonate, fine sand, cinder, common brick slag.
Further, application of the Wheat field weeding composition as described in the present invention in wheat paddock annual grassy weeds is prevented and kill off.
The preparation auxiliary element that the present invention is used includes emulsifying agent, wetting agent, dispersant, disintegrant, thickener, bonding
Agent, defoamer etc., are all the auxiliary agents commonly used in Pesticide formulation, are not particularly limited, and may refer to this area reference book (such as
" modern type process technology ", Liu Guangwen, printing time：On 01 01st, 2013；National standard book number ISBN：
9787122151643) or according to the conventional method of other this areas determine.
Product described in the invention can be provided in the form of finished product preparation, i.e., each material is blended in composition, group
The composition of compound can also single dose form provide, using it is preceding directly in tank or bucket mix, be then diluted to required for it is dense
Degree, when crop field is sprayed, the amount of application of active component is controlled in 50-200g/667m in composition2Within scope.
The present invention has made intensive studies to pinoxaden, isoproturon and florasulam mixture first, finds oxazoline grass
Ester, isoproturon and florasulam mixture have synergistic function to target weeds, especially have obvious collaboration to increase to deceiving grass
Effect is acted on, expands herbicide controlling spectrum.
Compared with prior art, the advantage of the invention is that：(1) after Herbicidal combinations two-spot compounding of the invention, synergy
Substantially, improve the prevention effect to weeds, reduce Pesticide use amount, reduce and apply cost.(2) weeding group of the invention
Compound broad weed-killing spectrum, can effectively prevent and kill off Alopecurus, amur foxtail, wild oat, caput it is careless, deceive grass, annual bluegrass, Triticum tauschii,
Various pernicious difficulties such as bromegrass, green bristlegrass, clearvers are cut weeds.(3) the Herbicidal combinations optimum period for applying fertilizer of the invention is wide, to when stubble and
Succession crop safety.(4) the Herbicidal combinations active ingredient mechanism of action of the invention is different, can delay herbicide resistance
Produce.
