Abstract
The invention discloses a pyribenzoxim-containing weeding composition. The pyribenzoxim-containing weeding composition comprises 1-20wt% of cyhalofop-butyl, 1-20wt% of pyribenzoxim, 1-30wt% of bensulfuron methyl and the balance an herbicide assistant. The pyribenzoxim-containing weeding composition is used for preventing and removing annual weeds in the paddy field, has weeding effects obviously superior to those of single-component weeding agents, has a wide weeding spectrum, improves real effects, delays production of herbicide resistance of weeds and saves time and labor.
Description
Technical field
The invention belongs to agricultural chemicals Herbicidal combinations, be specifically related to a kind of Herbicidal combinations that contains pyribenzoxim, is to take cyhalofop-butyl, pyribenzoxim and bensulfuron-methyl as active ingredient, for preventing and kill off paddy field annual weed.
Background technology
Chemical method weeding is one of Main Means of paddy field prevention and control weeds.Paddy field weed generation grass is complicated mutually, and the multiclass weeds such as grassy weed, broad leaved weed, sedge family are mixed raw, and single variety weed killer herbicide is used can not solve paddy field weed, all can show defect and limitation in a certain respect.By variety classes weed killer herbicide science, be mixed, there is the herbicidal spectrum of raising, promote actual effect, time and labour saving advantage.
Cyhalofop-butyl is in fragrant phenoxy phenoxy propionic acid weed killer herbicide, paddy rice to be had the kind of tight security.Cyhalofop-butyl is also interior suction conductivity weed killer herbicide, blade and leaf sheath by plant corpus absorb, phloem conduction, accumulate the meristem zone in plant corpus, suppress acetyl-CoA carboxylase, fatty acid is synthesized and stop, the growth division of cell can not normally be carried out, film systems etc., containing fat structural deterioration, finally cause plant dead.Cyhalofop-butyl, not only to moleplant seed, also can be prevented and treated the grassy weeds such as barnyard grass, Paspalum distichum, green foxtail, eleusine indica, amur foxtail.
Pyribenzoxim is novel oxime ester compound, wide spectrum selective post-emergence herbicide.Mechanism of action is similar to sulfonylurea and the slow-witted ketone weed killer herbicide of imidazoles, 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 2 weeks.Medicament medication appropriateness is wider, all effective to 1.5～6.5 leaf phases of barnyard grass.
Bensulfuron-methyl is selectivity inner-adsorption conduction-type herbicide.Active ingredient can be in water diffusion rapidly, for weeds root and blade absorb, transfer to each portion of weeds, the biosynthesis of hindered aminoacid, lysine, isoleucine, stops division and the growth of cell.Susceptible weeds GF is obstructed, and tender tissue turns to be yellow too early and suppresses the growth of leaf portion, hinders root growth and necrosis.It is harmless inertia chemicals that active ingredient enters rapid metabolism in paddy rice body, to rice safety.Using method is flexible, available pesticide-clay mixture, mispickel, spraying, sprinkles the method such as water.In soil, mobility is little, and temperature, soil property affect little on its herbicidal effect.
Variety classes weed killer herbicide is mixed, have herbicidal spectrum wide, promote actual effect, delay herbicide resistance, time and labour saving advantage.By mixed pesticide, screening, can effectively improve actual control efficiency, reduce dosage, reduce costs, delay the generation of herbicide resistance, is the important means that agricultural synthesis is administered.The inventor conducts in-depth research the formula of cyhalofop-butyl, pyribenzoxim and bensulfuron-methyl, find that cyhalofop-butyl, pyribenzoxim and bensulfuron-methyl are mixed, in certain mixed ratio scope, paddy field annual weed is had to synergy or summation action, after further study, completed the present invention.
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 paddy field weed comprehensive regulation.
Another object of the present invention is for preventing and kill off paddy field annual weed by this Herbicidal combinations.
Technical scheme: for achieving the above object, the invention provides a kind of Herbicidal combinations that contains pyribenzoxim, active ingredient is cyhalofop-butyl, pyribenzoxim and bensulfuron-methyl, the percentage by weight of cyhalofop-butyl in composition is 1%～20%, the percentage by weight of pyribenzoxim in composition is 1%～20%, the percentage by weight of bensulfuron-methyl in composition is 1%～30%, and all the other are insecticides adjuvant.The formulation of practical application is a kind of in suspending agent, wetting powder or water dispersible granules.
The auxiliary agent using in Herbicidal combinations of the present invention comprises solvent, emulsifier, wetting agent, stabilizing agent, dispersant, thickener, PH conditioning agent, defoamer, antifreezing agent, deionized water, filler etc., be all various auxiliary agents conventional in Pesticide formulation, concrete composition and consumption require to determine by simple test according to formula.
The production technology of the various application forms of Herbicidal combinations of the present invention all belongs to existing known technology, does not repeat them here.
Herbicidal combinations of the present invention, conventionally adopts and is watered spray method use, also can adopt as required other operation techniques of the upper application of agricultural.
Herbicidal combinations of the present invention, should be in the 2 leaf phases of paddy rice to the shooting stage in when application, and annual weed was used before the phase to 5 leaves after being unearthed.
Herbicidal combinations provided by the invention has following beneficial effect:
1, weeding Herbicidal combinations of the present invention, in certain ratio range, its synergy shows obvious synergistic effect, and the herbicidal effect of composition is significantly improved than each single dose, expands herbicidal spectrum.
2, weeding Herbicidal combinations of the present invention, active ingredient mechanism of action is different, and the application of composition can delay or overcome the generation of herbicide resistance, is conducive to agricultural synthesis and administers.
