Abstract
The invention discloses a wheat filed weeding combination. The wheat filed weeding combination comprises the following effective components by weight percentage: 1-20 percent of pyribenzoxim, 1-20 percent of carfentrazone-ethyl, 1-50 percent of fluroxypyr, and pesticide adjuvant in balancing amount. Pyribenzoxim, carfentrazone-ethyl and fluroxypyr have remarkable synergism after being compounded, and are used less in the compounded agent than to be used individually, so that the agent use cost is lowered, and the weeding combination is suitable for preventing and weeding weed in wheat fields.
Description
Technical field
The agricultural chemicals Herbicidal combinations the present invention relates to is that to take pyribenzoxim, azoles humulone, fluroxypyr be active ingredient, for preventing and kill off wheat paddock annual weed etc.
Background technology
The chemical method weeding is one of upper Main Means of controlling weeds of agricultural.In recent years, because some weed killer herbicide kind large tracts of land are used separately, caused a lot of weeds to develop immunity to drugs.Simultaneously, grass when weeds occur is complicated mutually, not only annual and perennial weed is mixed gives birth to, draft, liana and shrub have concurrently, and weeds emerge uneven, seed, the staggered generation of low age, advanced age weeds, so, when the weed killer herbicide kind is used separately, all can show defect and limitation in a certain respect.
Pyribenzoxim belongs to oxime ester compound, the wide spectrum selective post-emergence herbicide.Mechanism of action is similar to sulfonylurea and imidazolone weed killer herbicide, all belongs to acetolactate synthestase (ALS) inhibitor.Paddy rice, common wheat, Korea lawn grass are had to activity of weeding after selectivity super-high-efficient bud, without activity of weeding before bud, distinguished for preventing and kill off the various grassy weeds such as barnyard grass, large fringe amur foxtail, polygonum flaccidum and the assorted effect of drawing of broad-leaved, to paddy rice, common wheat safety.Chemical weeding speed is slower, after dispenser, can suppress weed growth, but must be withered after two weeks.Medicament medication appropriateness is wider, all effective to 1.5～6.5 leaf phases of barnyard grass.
The azoles humulone is a kind of contact killing type selective herbicide, having under the condition of light, in the chlcrophyll biosynthesis process, causes the accumulation of poisonous intermediate by suppressing proporphyrinogen oxidase, thereby destroys the cell membrane of weeds, makes blade withered, dead rapidly.Carfentrazoneethyl is absorbed by plant leaf blade in 15 minutes after the spray medicine, and it is not drenched with rain and affect, and after 3-4 hours, poisoning symptom just appears in weeds, death in 2-4 days.
Fluroxypyr is the inner sucting conduction type herbicide after seedling, after medicine, is absorbed by plants very soon, makes sensitive plant the reaction of typical hormone herbicide occur, and plant is lopsided, distortion, finally withered.Be applicable to the ground such as wheat, barley, corn, grape, orchard, pasture, forest land, lawn and prevent and kill off broad leaved weed; As clearvers, volume stem knotweed, kitchen garden, black nightshade, field bindweed, knotweed, amaranth etc., invalid to grassy weed.
When pyribenzoxim, azoles humulone, the single use of fluroxypyr, certain defect and limitation are all arranged.
The inventor conducts in-depth research pyribenzoxim, azoles humulone, being mixed of fluroxypyr, on the basis of a large amount of formula indoor screening tests and field medicine effect test, find that pyribenzoxim, azoles humulone, fluroxypyr are mixed, in certain mixed ratio scope, weeds of wheat is shown to obvious synergistic effect, after further study, completed the present invention.
Being mixed and applying of pyribenzoxim, azoles humulone, fluroxypyr there is no report at present.
Summary of the invention
The object of the invention is to solve in prior art to farmland weed develop immunity to drugs problem and actual control efficiency poor, provide a kind of efficient, low toxicity, quick-acting is good and the lasting period is long, is conducive to the Herbicidal combinations of the farmland weed comprehensive regulation.
Another object of the present invention is for preventing and kill off the wheat paddock annual weed by this Herbicidal combinations.
Technical scheme of the present invention: active ingredient is pyribenzoxim, azoles humulone, fluroxypyr, the percentage by weight of pyribenzoxim in composition is 1%～20%, the percentage by weight of azoles humulone in composition is 1%～20%, the percentage by weight of fluroxypyr in composition is 1%～50%, and all the other are in agricultural chemicals, to allow to use and the acceptable auxiliary element.
Herbicidal combinations of the present invention is prepared into and is applicable to upper any one formulation used of agricultural by known method, and reasonable formulation is wetting powder, suspending agent or water dispersible granules.
The auxiliary element used in Herbicidal combinations of the present invention comprises that solvent, dispersant, stabilizing agent, emulsifier, antifreezing agent, thickener etc. and other are of value to the known substance of active ingredient stable and performance drug effect in preparation, all various compositions commonly used in pesticidal preparations or that permission is used, be not particularly limited, concrete composition and consumption require to determine by simple test according to formula.
Product described in the invention can finished product preparation form provide, in composition, each material mixes, the form that the composition of composition also can single dose provides, and before use, directly in tank or bucket, mixes, and then is diluted to needed concentration.The frequency of administration of the present composition and amount of application change with weather condition and crop state variation, can reach the purpose of control by using suitable formulation.
Herbicidal combinations of the present invention is applicable to prevent and treat annual weed, especially the wheat paddock annual weed.
Compared with prior art, beneficial effect of the present invention is, composite have an obvious synergistic effect, improved control efficiency; Enlarged the control spectrum; Two kinds of active ingredients are composite, reduced the agricultural chemicals usage amount, thereby reduced cost and reduced the pollution to environment.
