Abstract
The invention relates to a florasulam and fenoxaprop-containing herbicidal composition as well as a preparation method and application thereof. The herbicidal composition consists of a compound (A) of florasulam and a compound (B) of fenoxaprop. The herbicidal composition is mixed according to a proper proportion and can be processed into normal pesticide formulations, such as wettable powder, suspending agents, water dispersible granules, and the like through modern pesticide preparation processing techniques and used for preventing and killing gramineae weeds and broadleaf weeds, such as cleavers, lithospermum arvense, rhizoma alismatis, vetches, chickweeds, pickpurses, silene, chorispora tenella, cardamine hirsute, stellaria alsine, polygonum convolvulus, wild oats, amur foxtail in cornfields. The preventing effect of the herbicidal composition is remarkably higher than that of the single compound (A) or the single compound (B), and the application dosage of each active substance is greatly reduced. The invention has not only ecological significance but also very important environmentally-friendly significance.
Description
Technical field
The present invention relates to have the Herbicidal combinations that improves performance, relate to specifically contain florasulam Yu Herbicidal combinations of fenoxaprop and uses thereof.
Background technology
The adopted name of compound (A) is a florasulam, and chemical name is 2 ', 6-two fluoro-5-ethyoxyl 8-fluoro-[1,2,4]-triazoles-[1,5-c] pyrimidine-2-sulfonanilide.
The English name of florasulam: florasulam.CA registration number: 145701-23-1.The exploitation unit is a company of The Dow Agrosciences, LLC., has obtained Chinese patent in May, 1989, patent publication No. position CNl030606C (3), CNl037605C (2).
Florasulam be a kind of be sulfonamides super-high-efficient weed killer herbicide, be used for wheat paddock and prevent and kill off broad leaved weed.Broad weed-killing spectrum can be prevented and kill off the most of broad leaved weeds of wheatland, comprises difficult anti-weeds such as clearvers, corn gromwell, and the most difficult wartwort of preventing and kill off in the wheatland is had extraordinary inhibitory action.The inner sucting conduction type weed killer herbicide can conduct to the weeds complete stool, thereby kills grass thoroughly, can not recur.Efficacy stability at low temperatures is even still can guarantee to stablize drug effect in the time of 2 ℃.。
The florasulam formulation of using on market at present mainly contains 50 grams per liter florasulam suspending agents.
The Chinese general fenoxaprop by name of compound (B), chemical name are (R)-2-[4-(6-chloro-l, 3-benzoxazole-2-base oxygen) phenoxy group] ethyl propionate, its common name is called fenoxaprop.
The English name of fenoxaprop is fenoxaprop-p-ethyl (BSI, ISO Draft), and trade name is galloping horse, Puma Super; The prestige despot, Whip Super.The CA registration number is 71283-80-2; 113158-40-0 (acid).
Fenoxaprop belongs to 2-(4-aryloxy group phenoxy group) propionic acid class weed killer herbicide, is the fatty acid synthetic inhibitor.Be transmitted to phyllopodium, stem, root after the blade absorption by plant, in the gramineous plants body, suppress the biosynthesis of fatty acid, the growth of growing tips of the plant is hindered, leaf chlorophyll content reduces, free amino acid and soluble sugar increase in stem, the leaf texture, the plant normal metabolic is damaged, and finally causes sensitive plant death.In broad leaf crop or broad leaved weed body, can in soil, be decomposed very soon by very fast metabolism, succession crop there is not influence.
Use the formulation and the preparation of De fenoxaprop to mainly contain aqueous emulsion and missible oil at present in market.
Fenoxaprop can be prevented and kill off the annual and perennial grassy weed in beet, paddy rice, cotton, flax, flower dirt, rape, potato, soybean and vegetables field mainly as post-emergence herbicide.
(B) fenoxaprop common characteristic is a herbicide after seedling, all can use in wheat paddock for compound (A) florasulam and compound.Compound (A) florasulam broad weed-killing spectrum, can prevent and kill off most of broad leaved weeds in the wheatland, comprise difficult anti-weeds such as clearvers, corn gromwell, and the most difficult wartwort of preventing and kill off in the wheatland is had extraordinary inhibitory action, but what control efficiency grassy weeds such as amur foxtail and wild oat are not had.And compound (B) fenoxaprop has excellent control efficiency to the wild oat in the wheatland, amur foxtail, but does not have control efficiency for broad leaved weed.Simultaneously for florasulam Yu fenoxaprop do not appear in the newspapers with the suitable ratio weeds that are used for preventing and kill off in the wheat paddock that are mixed.The use of composition not only can improve drug effect, reduces dosage, saves Financial cost, reduces medicament residual in environment.Simultaneously can also delay the drug-fast generation of weeds, prolong the service life of medicament.
Summary of the invention
The purpose of this invention is to provide florasulam Yu the Herbicidal combinations of fenoxaprop, after suitable ratio mixing, by modern pesticidal preparations process technology, be processed into conventional pesticide formulations such as wetting powder, suspending agent, water dispersible granules, be used for preventing and kill off the grassy weed and the broad leaved weed such as clearvers, corn gromwell, rhizoma alismatis, common vetch, chickweed, shepherd's purse, conical silene herb, ion grass, Hairy Bittercress, Stellaria alsine Grim., volume stem knotweed, wild oat, amur foxtail of wheatland.
Herbicidal combinations provided by the invention is characterized in that comprising compound (A) florasulam and compound (B) fenoxaprop.
Compound (A) is: florasulam.
Compound (B) is the: fenoxaprop.
Weight ratio between compound in Herbicidal combinations of the present invention (A) and the compound (B) generally is:
(weight ratio of B) fenoxaprop is 1-100: 1-100 for compound (A) florasulam and compound
Herbicidal combinations provided by the present invention can effectively be prevented and kill off grassy weed and broad leaved weeds such as clearvers in the wheatland, corn gromwell, rhizoma alismatis, common vetch, chickweed, shepherd's purse, conical silene herb, ion grass, Hairy Bittercress, Stellaria alsine Grim., volume stem knotweed, wild oat, amur foxtail.Preventive effect is significantly higher than the preventive effect of compound alone (A) or compound (B), and can reduce the application dosage of each bioactivator.
The present invention is used for preventing and kill off grassy weed and broad leaved weeds such as the clearvers, corn gromwell, rhizoma alismatis, common vetch, chickweed, shepherd's purse, conical silene herb, ion grass, Hairy Bittercress, Stellaria alsine Grim., volume stem knotweed, wild oat, amur foxtail of wheatland.This composition is handled as the cauline leaf spraying.
Adoptable surfactant has anion surfactant and non-ionic surface active agent.It comprises alkylsurfuric acid salt, alkyl sulfonic acid alkali metal salt and amido, dialkyl group succinate sodium sulfonate salt, alkylphenol polyoxyethylene formaldehyde condensation products sulfonate, sodium sulfate of polyethenoxy ether of fatty alcohol alkyl polyoxyethylene ether sulfate, alkylnaphthalene sulfonate, fatty acid or fatty acid ester sulphate, alkylphenol polyoxyethylene and fatty alcohol-polyoxyethylene ether etc.That can give an example has farming newborn 2000 series, lignosulfonates, NNO, a dispersing agent MF etc.
