Abstract
The invention discloses a ternary mixed weeding composition. Pyrazosulfuron-ethyl, pyribenzoxim and cyhalofop-butyl are used as active ingredients. The ternary mixed weeding composition comprises 1-10wt% of pyrazosulfuron-ethyl, 1-20wt% of pyribenzoxim, 1-30wt% of cyhalofop-butyl and the balance an herbicide assistant. According to application demands, the ternary mixed weeding composition can be processed to form a suspending agent, an oil suspending agent, wettable powder or water dispersible granules. The ternary mixed weeding composition is suitable for preventing and removing gramineous and broadleaved weeds in the paddy field. The ternary mixed weeding composition has weeding effects obviously superior to those of single-ingredient herbicides, has a wide weeding spectrum, improves actual effects, delays production of herbicide resistance of weeds, and saves time and labor.
Description
Technical field
The present invention relates to agricultural insecticide composition, specifically a kind of Ternary Herbicidal combinations, is to take pyrazosulfuron, pyribenzoxim and cyhalofop-butyl as active ingredient, for preventing and treating paddy field grass family and broad leaved weed.
Background technology
Chemical method weeding is one of upper Main Means of controlling weeds of agricultural.In recent years, because some weed killer herbicide kind large area are used separately, caused a lot of weeds to develop immunity to drugs.Meanwhile, grass when weeds occur is complicated mutually, and multiple weeds are mixed raw, and single variety weed killer herbicide is used can not solve farmland weed, all can show defect and limitation in a certain respect.Variety classes weed killer herbicide is mixed, have herbicidal spectrum wide, promote actual effect, delay herbicide resistance, time and labour saving advantage.
Pyrazosulfuron belongs to sulfonylurea herbicide, for selectivity inner-adsorption conduction-type herbicide, mainly by root system, is absorbed, and in weeds plant body, shifts rapidly, suppresses growth, and weeds are dead gradually.Paddy rice can be decomposed this medicament, on almost not impact of paddy growth.Efficacy stability, safe, lasting period 25-35 days.
Pyribenzoxim is pyrimidinylthiobenzoate herbicides, can be absorbed by the cauline leaf of plant, and conduction in vivo, suppresses the biosynthesis (being mainly that inhibition acetolactate synthestase is ALS) of sensitive plant branched-chain amino acid.Within after spray medicine 24 hours, suppress plant growth, within 3-5 days, occur yellow, 7-14 days withered.
Cyhalofop-butyl is only kind paddy rice to tight security in fragrant phenoxy phenoxy propionic acid weed killer herbicide, is interior suction conductivity weed killer herbicide.Blade and leaf sheath by plant corpus absorb, and phloem conduction, accumulates the meristem zone in plant corpus, resist 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.From cyhalofop-butyl, be absorbed into weeds Mortality Ratio slower, generally need 1-3 week.
Variety classes weed killer herbicide is mixed, have herbicidal spectrum wide, promote actual effect, delay herbicide resistance, time and labour saving advantage.By formulation of pesticide, screening, can effectively improve actual control efficiency, reduce dosage, reduce costs, delay disease, worm, the drug-fast generation of crop smothering, is the important means that agricultural synthesis is administered.The inventor conducts in-depth research the formula screening of pyrazosulfuron, pyribenzoxim and cyhalofop-butyl, find that pyrazosulfuron, pyribenzoxim and cyhalofop-butyl are mixed, in certain mixed ratio scope, paddy field grass family and broad leaved weed are 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 composition pesticide of the paddy field weed comprehensive regulation.
Technical scheme: for achieving the above object, the invention provides a kind of Ternary Herbicidal combinations, active ingredient is pyrazosulfuron, pyribenzoxim, cyhalofop-butyl.The percentage by weight of pyrazosulfuron in composition is 1%-10%, and the percentage by weight of pyribenzoxim in composition is that 1%-20%, the cyhalofop-butyl percentage by weight in composition is 1%-30%, and all the other are insecticides adjuvant.The formulation of practical application is a kind of in suspending agent, oil-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 adjusting agent, defoamer, antifreezing agent, deionized water, filler etc., be all various auxiliary agents conventional in Pesticide formulation, concrete composition and consumption required simple test to determine 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 provided by the 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 used at paddy field grass family and broadleaved herb weeds 3-4 leaf phase in use.
Herbicidal combinations provided by the invention has following beneficial effect:
1. Herbicidal combinations provided by the invention shows obvious synergistic effect in certain ratio range, and the herbicidal effect of composition is significantly improved than each single dose, has reduced the using dosage of agricultural chemicals, has reduced cost.
2. the active ingredient mechanism of action of Herbicidal combinations provided by the invention is different, and the application of composition can delay or overcome the generation of herbicide resistance, is conducive to agricultural synthesis and administers.
