Abstract

The invention discloses a three-ingredient weeding composition and application thereof. Effective active ingredients consist of a first active ingredient of fluroxypyr, a second active ingredient of cyhalofop-butyl and a third active ingredient of quinclorac according to a mass ratio of (1 to 90): (1 to 90): (1 to 90). The composition can be used for preparing agricultural allowable water dispersible granules, wettable powder, suspending agents, missible oil and dispersible oil suspending agents. The three-ingredient weeding composition has the advantages that the ingredients are reasonable; the weeding effect on paddy field is good; in addition, the activity and the weeding effect are not the simple overlapping effect of the activity of each ingredient. Compared with the existing single-ingredient preparation or two-ingredient compounding preparation, the three-ingredient weeding composition has the advantages that the obvious weeding effect is achieved; in addition, the obvious synergistic effect is also achieved; the herbicide controlling spectrum is increased; the weed prevention and removal cost can be reduced; the safety on crops is high.

Description

A kind of ternary weeding composition
Technical field
The present invention relates to a kind of rice terrace ternary weeding composition, by active component fluroxypyr, cyhalofop-butyl and Dichloro quinolinic acid and auxiliary agent composition, belong to technical field of compounded pesticide.
Background technology
Fluroxypyr, English name is fluroxypyr, and chemical name is：The fluoro- pyrrole of the chloro- 6- of 4- amino -3,5- two Pyridine -2- pyridine fluoroacetic acid 1- methyl-heptyl ester.Inner sucting conduction type herbicide after seedling.It is absorbed by plants quickly after medicine, make sensitive plant The reaction of classical hormones class herbicide, plant deformity, distortion in thing.Temperature no affects on the final effect of its weeding, but shadow Ring the speed that its drug effect plays.Typically when temperature is low, drug effect plays relatively slowly, stops growing after can making dunsiekte, but not immediately Dead；After temperature raises, plant is dead quickly.In soil, leaching is not notable, and major part is distributed in 0-10 centimetre of topsoil, Under conditions of aerobic, it is degraded into the non-poisonous materials such as 2- pyridine alcohol quickly in the effect of edaphon, the half-life is relatively in soil Short, impact will not be produced on lower stubble broad leaf crop.
Cyhalofop-butyl, English name cyhalofop-butyl, chemical name is：(R) -2- [4 (4- cyano group -2- fluorobenzene oxygen Base) phenoxy group]-butyl propionate.Cyhalofop-butyl is that uniquely have tight security to paddy rice in fragrant phenoxy phenoxy propionic acid herbicide Kind, be Uptake and translocation herbicide.Absorbed by the blade and leaf sheath of plant, bast conducts, and accumulates in plant Meristem zone, resists acetyl-CoA carboxylase, so that aliphatic acid is synthesized and stops, and the growth division of cell can not be normally carried out, film The structures containing fat such as system are destroyed, and finally result in Plant death.
Dichloro quinolinic acid, English name quinclorac, chemical name is：3,7- bis- chloro- 8-Quinoline Carboxylic Acids, are preventing and treating rice The special efficacy selective herbicide of field barnyard grass, projects to 4-7 leaf phase barnyard grass effect.Selectively strong, the amplitude broad in dispenser period, once Dispenser can control the barnyard grass of whole growth period duration of rice.Monochoria vaginalis, Chinese celery etc. can also effectively be prevented and kill off.Preventing and treating effect to sedge weed Really poor.Seed, root and leaf portion that this compound can be sprouted absorb, and have the characteristics that hormone like herbicide, with auxins thing The effect symptom of matter is similar.In the detailed mode of action in plant body still among research.Slight mistake in aggrieved barnyard grass tender leaf Green phenomenon, longitudinal stripe and bends in blade.This compound has larger mobility in soil, can be divided by edaphon Solution.
Applicant finds through retrieval, does not still have fluroxypyr, cyhalofop-butyl and dichloro quinolinic acid three to compound at present Composition patent.Simultaneously through long-term test it was unexpectedly observed that will fluroxypyrs different for the mechanism of action, cyanogen fluorine grass Ester and dichloro quinolinic acid compound, and rice terrace barnyard grass, lady's-grass, moleplant seed, Monochoria vaginalis, alternanthera philoxeroides are had obvious synergy and make With, significantly improve the prevention effect to rice terrace grassy weed and broad leaved weed, expand weed control spectrum, reduce cost accounting, Improve to crop safety.
Content of the invention
It is an object of the invention to provide a kind of component is rationally, drug cost is low, and synergistic effect is notable, and herbicidal effect is good, Preventing and treating spectrum is wide, the ternary weeding composition to crop safety.
Another object of the present invention is to providing above-mentioned ternary weeding composition preparation formulation.
It is still another object of the present invention to provide above-mentioned composition is on preventing and treating rice terrace grassy weed and broad leaved weed Application.
For the defect overcoming existing unitary agent or two-spot to compound, the technical scheme of Herbicidal combinations of the present invention is so Solve：
A）First active component fluroxypyr；
B）Second active component cyhalofop-butyl；
C）3rd active component dichloro quinolinic acid.
First active component, the second active component and the 3rd active component mass ratio are（1～90）：（1～90）：（1～ 90）.

Specific embodiment
To illustrate that fluroxypyr, cyhalofop-butyl and dichloro quinolinic acid compound to paddy rice below by Toxicity Determination Field grassy weed and the synergistic effect of broad leaved weed.
In order to prevent and treat rice terrace grass family and broad leaved weed, we are with fluroxypyr, cyhalofop-butyl and dichloroquinoline The synergy research that acid is mutually compounded, test method reference《People's Republic of China (PRC) agricultural industry criteria NY/ T1155.4 2006 farm-chemical indoor determination test rule herbicide the 4th part：Active determination test cauline leaf spray-on process》 With《People's Republic of China (PRC) agricultural industry criteria NY/T1155.7 2006 farm-chemical indoor determination test rule herbicide 7th part：The synergy of mixture measures》.
Subjects are rice direct seeding field grassy weed barnyard grass（Echinochloa crusgalli）, lady's-grass （Digitaria sanguinalis）, moleplant seed（Leptochloachinensis）, broad leaved weed Monochoria vaginalis（Monochoria vaginalis）, alternanthera philoxeroides（Alternanthera Philoxeroides）.
Active compound is configured to the test medicine needing, first single dose and each compound drug is arranged 5 variable concentrations gradients （On the basis of pilot study result, different according to dosages distribution, concentration gradient setting is also different, rate of preventing and kill off 5%～ Press geometric progression in the range of 90% to set）.If clear water compares, it is repeated 4 times.Weeds were in for 2～3 leaf phases, from low dosage to high agent Amount carries out spraying treatment respectively.It is placed in culture in greenhouse after process to observe, with the bottom infiltrating irrigation mode moisturizing of basin alms bowl.
Process the rear fresh weight preventive effect calculating each chemicals treatment for 21 days, by the probit value of preventive effect and the logarithm value of series concentration Between linear regression analysis, obtain the ED of each medicament50Value, calculates the co-toxicity coefficient of mixture with the abundant method of Sun Yun（CTC）, come with this Evaluate the activity to weeds for the reagent agent.
Co-toxicity coefficient CTC >=120 of complex preparation show as synergistic effect；CTC≤80 show as antagonism；80 ＜ CTC ＜ 120 shows as summation action.
