Description
Technical field
The present invention relates to a kind of weed killer herbicide, especially a kind of Herbicidal combinations containing pendimethalin and ethoxysulfuron and preparation thereof and application.
Background technology
Often there is defect in various degree in the weed killer herbicide kind containing single-activity component, as after continuous administration, weeds easily develop immunity to drugs, herbicide spectrum is narrow on Agriculture Field control of weeds, and application times is many can weighting ring environment pollution.The weeds of resistance are agriculturally produced for control, a kind of way be release new for the new component of existing kind without cross resistance.But the development cost of new active ingredient is high, and the construction cycle is long, and forever all do not catch up with the speed that weeds produce resistance.Other way such as crop structure adjustment, different agricultural chemicals rotations etc., in the process of practical operation, be difficult to really play obvious effect.Different cultivars composition carries out composite, is the modal method of control resistant weed.
Compound herbicide is made up of the active ingredient of different mechanism of action, and action site increases, and being conducive to the generation overcoming and delay herbicide resistance, is the important means of integrated control weeds in field.
Pendimethalin (Pendimethalin) chemical name is: N-(1-ethyl propyl)-2,6-dinitro-3,4-dimethylaniline, be known in BE816837, US4199669, belong to dinitroaniline herbicide, main suppression meristem cell division, does not affect the sprouting of weed seed.Worked by young shoot, stem and root absorption in suppressing weed seed germination process, its damage symptoms is that young shoot and secondary root are suppressed.Be applicable to prevent and kill off annual gramineous weed and some broad leaved weed in soybean, corn, cotton, tobacco, peanut and various vegetables and orchard, as weeds such as lady's-grass, green foxtail, eleusine indica, annual bluegrass, barnyard grass, lamb's-quarters, amaranth and knotweeds.
Ethoxysulfuron (Ethoxysulfuron) chemical name is: 1-(4, 6-dimethoxypyridin-2-base)-3-(2-phenoxy ethoxy sulfonyl) urea, be known in: CN101401569A, belong to sulfonylurea herbicide, for branched chain amino acid synthesis (ALS or AHAS) inhibitor, by blocking the biosynthesis of basic amino acid valine and isoleucine, thus stop cell division and plant growth, there is good selectivity, be mainly used in preventing and kill off broad leaved weed and sedge weed, to wheat, paddy rice, the safety such as sugarcane, and on succession crop without impact.
Oxaziclomefone (Oxaziclomefone) chemical name is: 3-[1-(3,5-dichlorophenyl)-1-Methylethyl]-2,3-dihydro-6-methyl-5-phenyl-4H-1,3-oxazine-4-ketone, be known in EP0605726; belong to oxazine type herbicides, be mainly used to prevent and kill off important broad leaved weed, sedge weed and Echinochloa weeds etc., except barnyard grass has special efficacy, also can be used for Kill weeds, to rice safety, succession crop wheat, barley, carrot, Chinese cabbage, onion etc. are had no adverse effects.
Pyribenzoxim (Pyribenzoxim) chemical name is: O-[2; 6-two-(4; 6-dimethoxy-2-pyrimidine radicals) oxygen base benzoyl] diphenyl-ketoxime; be known in EP0658549, US5521146; belong to pyrimidinylthiobenzoate herbicides; by suppressing protoporphyrinogen oxidase, suppressing Chlorophyll synthesis, reaching herbicidal effect.It is good that this medicament plants broad leaved weed preventive effect to more than 90; effect is fast; lasting period is long, effectively can prevent and kill off the large seed subclass weeds of the arabica such as lamb's-quarters, grey dish subclass broad leaved weed and the more difficult prevention and control such as sunflower, morning glory, have higher effect to part grassy weeds such as barnyard grasses.Simultaneously to the safety such as Rice And Maize, soybean, show good plant selectable.
There is no pendimethalin and ethoxysulfuron at present, or the complex preparation of Fu Yi oxaziclomefone or pyribenzoxim is again disclosed.
Summary of the invention
For for above-mentioned Problems existing, an object of the present invention is to provide a kind of containing pendimethalin, ethoxysulfuron, or the Herbicidal combinations of Fu Yi oxaziclomefone or pyribenzoxim again, this Herbicidal combinations resistance risk is little, cost accounting is low, broad weed-killing spectrum, good drug efficacy, lasting effect and quick-acting all good, environmental pollution is little.What is more important retransmits to current paddy field the grassy weed such as barnyard grass, moleplant seed, Paspalum distichum being difficult to prevent and kill off special efficacy, and increasingly sharpens to flat stalk Fischer grass, mexicana, rhizoma alismatis etc. and be difficult to the nutgrass flatsedge of preventing and kill off and broadleaved herb has special efficacy equally.Second object of the present invention is to provide a kind of Herbicidal combinations preparation adopting above-mentioned composition.3rd object of the present invention is to provide above-mentioned composition and the application of preparation.
In order to realize first above-mentioned object, present invention employs following technical scheme:
Contain a Herbicidal combinations for pendimethalin and ethoxysulfuron, include effective constituent A and effective ingredient B, effective ingredient A is pendimethalin, and effective ingredient B is ethoxysulfuron.
When in Herbicidal combinations of the present invention, active ingredient exists with extra fine quality ratio, synergy highly significant.Therefore described pendimethalin and the mass ratio of ethoxysulfuron are 1:100 ~ 100:1, and preferred mass, than being 1:50 ~ 50:1, most preferably is 1:15 ~ 10:1.
Pendimethalin and ethoxysulfuron use by the present invention, obviously can strengthen herbicidal effect, broad weed-killing spectrum, security performance is high, production-increasing function is remarkable, dispenser is convenient, toxicity is low, the grassy weed such as barnyard grass, moleplant seed, Paspalum distichum being difficult to prevent and kill off is retransmitted to current paddy field and has special efficacy, and flat stalk Fischer grass, mexicana, rhizoma alismatis etc. are increasingly sharpened and is difficult to the nutgrass flatsedge of preventing and kill off and broadleaved herb has special efficacy equally.
Containing pendimethalin and ethoxysulfuron with and the Herbicidal combinations of oxaziclomefone or pyribenzoxim, this Herbicidal combinations comprises effective constituents A, B and C, and described A is pendimethalin, and B is ethoxysulfuron, and C is oxaziclomefone or pyribenzoxim; The mass ratio of effective constituents A, B and C is A: B: C=1 ~ 60: 0.1 ~ 20: 0.1 ~ 50.
Described pendimethalin, ethoxysulfuron, Yu the mass ratio of oxaziclomefone is preferably 1 ~ 30: 0.1 ~ 20: 0.1 ~ 20, most preferably are 3 ~ 15: 0.2 ~ 10: 0.5 ~ 5; Pendimethalin, ethoxysulfuron and pyribenzoxim mass ratio are preferably 1 ~ 30: 0.1 ~ 20: 0.2 ~ 20, most preferably are 3 ~ 15: 0.1 ~ 10: 0.5 ~ 5.
Above effective constituents A, B and C tri-kinds of medicaments are without cross resistance, carried out mixture, its soil sealing process of energy efficient hardening, kill the weeds not germinateing and germinateed comprehensively, expanding prevention can compose on a large scale, extensively kill the multiple weeds comprising grass family, sedge family, broad-leaved class, improve its quick-acting and lasting effect, reducing the times for spraying of breeding time, having very important meaning to delaying drug resistance generation.Meanwhile, because single medicament working concentration declines, the risk that poisoning occurs is greatly reduced.Meet a medicine in agricultural production multiplex, reduce times for spraying, reduce the requirement of poisoning risk.
