Abstract
The invention discloses a kind of Wheat field weeding composition, effective ingredient is pyribenzoxim, azoles oxadiazon, fluroxypyr, pyribenzoxim percentage by weight in the composition is 1%~20%, azoles oxadiazon percentage by weight in the composition is 1%~20%, fluroxypyr percentage by weight in the composition is 1%~50%, and all the other are insecticides adjuvant.Having notable synergistic effect after pyribenzoxim, azoles oxadiazon, fluroxypyr are composite, compound drug effective ingredient consumption ratio is used alone and significantly reduces, and reduces drug cost, it is adaptable to eliminating weed in wheat field.
Description
Technical field
The pesticide Herbicidal combinations that the present invention relates to, is with pyribenzoxim, azoles oxadiazon, fluroxypyr for effective ingredient, is used for preventing and kill off wheat paddock annual grassy weeds etc..
Background technology
Chemical method weeding is agriculturally one of Main Means controlling weeds.In recent years, owing to some herbicide kind large area are used alone, already lead to a lot of weeds and develop immunity to drugs.Simultaneously, grass when weeds occur is mutually complicated, not only annual and perennial weeds is mixed raw, draft, liana and shrub have concurrently, and weeds emerge uneven, seed, low age, the staggered generation of weeds at advanced age, so when herbicide kind is used alone, defect in a certain respect and limitation all can be shown.
Pyribenzoxim belongs to oxime ester compound, wide spectrum selective post-emergence herbicide.Mechanism of action is similar to sulfonylurea and imidazolone herbicide, all belongs to acetolactate synthestase (ALS) inhibitor.Oryza sativa L., common wheat, Korea lawn grass are had activity of weeding after selectivity ultra high efficiency bud, without activity of weeding before bud, is used for preventing and kill off the various grassy weeds such as barnyard grass, big fringe amur foxtail, Herba polygoni hydropiperis and assorted stroke of effect of broad-leaved is distinguished, to Oryza sativa L., common wheat safety.Chemical weeding speed is relatively slow, can suppress weed growth after dispenser, but must be withered after two weeks.Medicament medication appropriateness is wider, and barnyard grass 1.5~6.5 leaf phase is all effective.
Azoles oxadiazon is a kind of contact killing type selective herbicide, when there being light, in chlcrophyll biosynthesis process, by suppressing proporphyrinogen oxidase to cause the accumulation of poisonous intermedium, thus destroying the cell membrane of weeds, makes blade withered, dead rapidly.Namely carfentrazoneethyl is absorbed by plant leaf blade in 15 minutes after spray medicine, and it is not drenched with rain affects, and after 34 hours, weeds occur as soon as poisoning symptom, and 24 days dead.
Fluroxypyr is inner sucting conduction type herbicide after seedling, is quickly absorbed by plants after medicine, makes sensitive plant the reaction of classical hormones class herbicide occur, plant deformity, distortion, finally withered.Broad leaved weed is prevented and kill off suitable in Semen Tritici aestivi, Fructus Hordei Vulgaris, Semen Maydis, Fructus Vitis viniferae, orchard, pasture, forest land, lawn and other places;Such as Herba Galii Teneri, roll up stem knotweed, Herba Portulacae, Herba Solani Nigri, Herba seu Flos Convolvuli arvensis, knotweed, Herba Amaranthi tricoloris etc., grassy weed is invalid.
Pyribenzoxim, azoles oxadiazon, fluroxypyr single use time, all have certain defect and limitation.
The present inventor to pyribenzoxim, azoles oxadiazon, fluroxypyr mixture conduct in-depth research, on the basis of substantial amounts of formula indoor screening test and field medicine effect test, find that pyribenzoxim, azoles oxadiazon, fluroxypyr carry out mixture, within the scope of certain mixed ratio, weeds of wheat is shown obvious potentiation, after further study, the present invention is completed.
Pyribenzoxim, azoles oxadiazon, fluroxypyr mixture and application there is no report at present.
Summary of the invention
It is an object of the invention to solve farmland weed is developed immunity to drugs by prior art problem and actual prevention effect poor, it is provided that a kind of efficient, low toxicity, quick-acting are good and the lasting period is long, are conducive to the Herbicidal combinations of farmland weed comprehensive control.
It is another object of the present invention to be used for this Herbicidal combinations preventing and kill off wheat paddock annual grassy weeds.
Technical scheme: effective ingredient is pyribenzoxim, azoles oxadiazon, fluroxypyr, pyribenzoxim percentage by weight in the composition is 1%~20%, azoles oxadiazon percentage by weight in the composition is 1%~20%, fluroxypyr percentage by weight in the composition is 1%~50%, and all the other are allow in pesticide to use and acceptable auxiliary element.
Herbicidal combinations of the present invention prepares into any one dosage form being suitable for agriculturally using by known method, and reasonable dosage form is wettable powder, suspending agent or water dispersible granules.
The auxiliary element used in Herbicidal combinations of the present invention includes solvent, dispersant, stabilizer, emulsifying agent, antifreezing agent, thickening agent etc. and other are of value to the known substance that effective ingredient is stablized in the formulation and played drug effect, it is all conventional in pesticidal preparations or permission use various compositions, being not particularly limited, concrete composition and consumption are determined by simple test according to recipe requirements.
Product described in the invention can the form of finished product preparation provide, and namely in compositions, each material is blended, and the composition of compositions can also the form of single dose provide, and directly mixes in tank or bucket, be then diluted to required concentration before using.The frequency of administration of the present composition and amount of application change with weather condition and crop condition and change, it is possible to by using suitable dosage form to reach the purpose of preventing and treating.
Herbicidal combinations of the present invention is applicable to preventing and treating annual grassy weeds, especially wheat paddock annual grassy weeds.
Compared with prior art, the beneficial effects of the present invention is, composite have obvious potentiation, improves prevention effect;Expand preventing and treating spectrum;Two kinds of effective ingredient are composite, reduce Pesticide use amount, thus reducing cost and decreasing the pollution to environment.
