Description
Technical field
The invention belongs to agrochemicals field, problem is prevented and kill off for wheat paddock annual grassy weeds is solved more particularly, to one kind
Herbicidal combinations.
Background technology
Diflufenican (diflufenican) belongs to acetamide-group herbicides, herxheimer-liked reaction inhibitor.Located
Carotenoid content declines in the plant of reason, and then causes chlorophyll to be destroyed, and membranolysis, weeds show as young shoot and take off
Color or white, finally result in death.Can be used for before seedling or after seedling after Wheat Sowing and prevent and kill off clearvers, field viola, Veronica, Bao Gai
Grass etc..
Isoproturon (isoproturon) belongs to photosynthesis electron transfer inhibitor, belong to substituted urea class selectivity before seedling,
Herbicide after seedling, medicament mainly absorbs through weeds root and cauline leaf, leaf is transmitted to upwards with moisture in conduit, in green cell
Play a role, disturb photosynthetic carrying out.Can be used for winter or the weeding of spring wheat field, to annual gramineous weed and broad-leaved
The weeds such as weeds such as lady's-grass, annual bluegrass, amur foxtail, small lamb's-quarters, chickweed are effective.
Thifensulfuronmethyl (thifensulfuron-methyl) belongs to sulfonylurea acetolactate synthestase (ALS) inhibitor,
Medicament is absorbed and conducted rapidly by plant roots, and the biology of valine, leucine and isoleucine can be suppressed in sensitive plant body
Synthesize and prevent cell division, sensitive plant is stopped growing, it is dead in 1~3 week after medicine.Can be used for preventing and kill off it is annual and
The perennial broadleaf weed such as broad leaved weed such as cylinder fiber crops, black nightshade, Amaranthus retroflexus.
The chlorine of 2 first 4 (MCPA) or its salt or its ester belong to phenoxy acetic acid class selectivity hormone like herbicide, are easily root and leaf
Portion absorbs, and is mainly used in preventing and kill off various annual and perennial broadleaf weed in the regions such as paddy rice, wheat, pea, lawn, to perfume (or spice)
Monkshood, convexutricle sedge herb, sweet wine intestines, Monochoria vaginalis, angustifolia arrowhead herb and other effects are notable, but substantially invalid to grassy weed.
There is different degrees of defect in the herbicide kind containing single-activity component, on control of weeds such as after continuous use
Weeds easily develop immunity to drugs, and herbicide controlling spectrum narrows, the problems such as cause environmental pollution.
Rationally compounding is to improve preventive effect, expand herbicide controlling spectrum, widen use time to herbicide, delays shift of weed community
Speed, reduce that agricultural chemicals is single to use brought resistance risk, mitigate the pollution to environment, reduce use cost and mitigation removed
A kind of effective ways of careless agent residual.
The content of the invention
In order to overcome the deficiencies in the prior art, the present invention provides that a kind of, toxicity higher to crop safety is low, residual less,
Broad weed-killing spectrum, the ternary built Herbicidal combinations that can effectively delay herbicide resistance.
The technical solution adopted for the present invention to solve the technical problems is：A kind of ternary built Herbicidal combinations, institute are provided
Each component includes by weight percentage in the herbicide stated：Active ingredient 10~80%, pesticidal preparations auxiliary element 20~90%,
The first active ingredient is diflufenican, and second active ingredient is isoproturon, and the third active ingredient is thifensulfuronmethyl, 2
Any one in the chlorine of first 4 or its salt or its ester, the first active ingredient, second active ingredient and the third active ingredient
Weight ratio be (10~30)：(50~150)：(1~8).
Further, described Herbicidal combinations formulation is water dispersible granules, wettable powder etc..
Further, it is carrier, surfactant etc. that described Herbicidal combinations process formulation auxiliary element.
Further, the carrier in Herbicidal combinations of the present invention is kaolin, fine particle calcium carbonate, cornstarch, white carbon
One or more in.
Further, the surfactant in Herbicidal combinations of the present invention is selected from calcium dodecyl benzene sulfonate, wood
Mahogany sulfonate, styrylphenol polyoxyethylene ether, alkylaryl polyoxyethylene poly-oxygen propylene aether, polyoxyethylene polyoxypropylene
One or more in block copolymer, APES phosphate etc..
Further, described Herbicidal combinations can be used for preventing and kill off wheat paddock annual grassy weeds.
The frequency of use and usage amount of Herbicidal combinations of the invention with plant growth, weeds occur, Changes in weather and
There is a small amount of change, the purpose of effective preventing and treating can be reached by using appropriate dosage.
The first active ingredient of its active component of Herbicidal combinations of the present invention is diflufenican, and second effective
Composition is isoproturon, and the third active ingredient is any one in thifensulfuronmethyl, the chlorine of 2 first 4 or its salt or its ester, and the first has
Effect composition, second active ingredient and common use after the third active ingredient compounding, with notable synergistic effect, overcome
Herbicidal performance containing single-activity component is not enough, while the generation of herbicide resistance can be delayed, reduces production cost and use cost,
Expand herbicide controlling spectrum, can effectively prevent and kill off wheat paddock annual grassy weeds, its have efficiently, low toxicity, low-residual, low cost etc. it is many excellent
Point, is that rear before seedling closing herbicide is broadcast in a kind of novel wheat field.
The agricultural chemicals such as surfactant used and carrier auxiliary element belongs to environmentally friendly type in Herbicidal combinations of the invention, low
Poison, low-residual, to wheat safety, will not produce murder by poisoning to crop, fishes and shrimps and water body in use.
Specific embodiment
In order that those skilled in the art are better understood from the present invention program, below by the technology in inventive embodiments
Scheme carries out clear, complete description.
It is raw to survey embodiment 1
Illustrate that diflufenican, isoproturon and thifensulfuronmethyl mixture prevent and kill off wheat paddock below by Toxicity Determination miscellaneous
The synergistic effect of grass.
For eliminating weed in wheat field, inventor is carried out with active component diflufenican, isoproturon and thifensulfuronmethyl
The mutually synergy of compounding is studied, and specific method is：Experiment target is designated as the wild old stork of the main broad leaved weed of wheat paddock.Active compound is configured to
The test medicine of needs, test method reference《In People's Republic of China's agricultural industry criteria NY/T1155.7-2006 agricultural chemicals room
The part of bioassay test criterion herbicide the 7th：The synergy of mixture is determined》.Single dose and each Mixed Pharmacy are set first
Into 5-7 various concentrations.If clear water is compareed, it is repeated 4 times.Using before seedling soil spray-on process, get ready in advance for examination target, treat target
Two days after broadcasting, the medicament that will have been diluted spray tower (Nanjing Agriculturing Mechanization Inst., Ministry of Agriculture, 3WPSH-500D, spraying pressure
Power 3.0kg/cm3) it is uniform be sprayed onto on examination target, after be placed in greenhouse and normally cultivate, calculated with ocular estimate within 21 days after treatment
The preventive effect of each chemicals treatment, by the linear regression analysis between the probit value of preventive effect and the logarithm value of series concentration, obtains each
The ED of medicament50Value, the co-toxicity coefficient (CTC) of mixture is calculated with the abundant methods of Sun Yun；CTC shows as synergistic effect more than or equal to 120；
CTC shows as antagonism less than or equal to 80；Summation action is shown as more than 80 and less than 120.
The Toxicity Determination of the diflufenican of table 1, isoproturon and thifensulfuronmethyl mixture to wild old stork
