Description

A kind of ternary weeding composition containing pinoxaden

Technical field

The present invention relates to a kind of cornfield herbicidal composition, by active component pinoxaden, pyroxsulam, fluorine chloropyridine ester or One kind and auxiliary agent composition in fluroxypyr, belongs to technical field of compounded pesticide.

Background technology

Pinoxaden, English name is pinoxaden, and chemical name is：2,2- dimethyl-propiolic acid 8- (2,6- diethyls Base -4- methylphenyls) -9- oxygen -1,2,4,5-4 hydrogen -9H- pyrazoles [1,2-d] [1,4,5] oxygen phenodiazine Zhuo -7- base esters.Belong to new benzene Base pyrazolines herbicide, the mechanism of action is acetyl-CoA carboxylase（ACC）Inhibitor.Aliphatic acid biosynthesis block is caused, is made thin Intracellular growth division stops, and cell membrane is destructurized containing fat, causes weeds dead.With Uptake and translocation, it is mainly used in wheatland Prevent and kill off annual gramineous weed.Through field practical proof, pinoxaden is preferable to wheat paddock amur foxtail, hard grass, not careless effect, It is poor to annual bluegrass, Triticum tauschii, bromegrass effect.

Pyroxsulam, English name is pyroxsulam, and chemical name is：N- (5,7- dimethoxys [1,2,4] triazoles [1,5- α] pyrimidine -2-base) -2- methoxyl groups -4- (trifluoromethyl) -3- pyridine sulfonamides.

Belong to sulfonamides inner sucting conduction type, selective winter wheat field herbicide after seedling, broad weed-killing spectrum, activity of weeding be high, Drug action is fast.The mechanism of action is acetolactate synthestase（ALS）Inhibitor, via grass cutting blade, sheath portion, stem or root Absorb, in growing point accumulation, suppress the synthesis of acetolactate synthestase, lead to not synthesize branched-chain amino acid, and then influence egg The synthesis of white matter, influences weeds cell division, causes weeds to stop growing, then dead.Can effectively prevent and kill off wheatland amur foxtail, day The grassy weeds such as this amur foxtail, hard grass, bromegrass, wild oat, Veronica, Descurainia sophia, shepherd's purse, chickweed and broad leaved weed.

Fluorine chloropyridine ester, English name is halauxifen-methyl.Be by Tao benefit agriculture research and develop one kind activity into Point, can be used as pyridine carboxylic acid class herbicide, the ISO common names of the active component get the Green Light in November, 2012.Tao benefit agriculture Methyl esters fluorine chloropyridine ester for the compound has carried out the market development, is released in Canadian cereal crops market, after bud Broad leaved weed prevention and control.Can be used to prevent and kill off broad leaved weed in various crop, be considered the new tool of Weed Resistance management.Contain fluorine chlorine The herbicide of pyridine ester can be by preventing and kill off the resistant weeds of Group 2, and such as clearvers, chickweed and cannabis weeds carry out resistance pipe Reason.Additionally, fluorine chloropyridine ester can be by microorganism fast degradation in the environment, for succeeding crop plantation provides larger flexible Property.

Fluroxypyr, English name is fluroxypyr, and chemical name is：The chloro- fluoro- pyrroles of 6- of 4- amino -3,5- two Pyridine -2- pyridine fluoroacetic acid 1- methyl-heptyl esters.Inner sucting conduction type herbicide after seedling.It is absorbed by plants quickly after medicine, makes sensitive plant There is the reaction of classical hormones class herbicide, plant deformity, distortion in thing.Temperature is on the final effect of its weeding without influence, but shadow Ring the speed that its drug effect is played.The general drug effect when temperature is low plays relatively slow, is stopped growing after can making dunsiekte, but not immediately It is dead；Plant is dead quickly after temperature is raised.Leaching is not notable in soil, and major part is distributed in 0-10 centimetres of topsoil, Under conditions of aerobic, the non-poisonous materials such as 2- pyridine alcohol are degraded into quickly in the effect of edaphon, in soil half-life period compared with It is short, influence will not be produced on lower stubble broad leaf crop.

Applicant has found through retrieval, at present still without pinoxaden, pyroxsulam, fluorine chloropyridine ester or fluroxypyr In a kind of compounding composition patent.Simultaneously by long-term experiment it was unexpectedly observed that the different oxazoline of the mechanism of action is careless A kind of compounding in ester, pyroxsulam, fluorine chloropyridine ester or fluroxypyr, to wheat paddock amur foxtail, Alopecurus, Wang Grass, hard grass, rye grass, clearvers, chickweed, Descurainia sophia, Veronica have obvious synergistic effect, significantly improve to wheatland standing grain Undergraduate course weeds and the prevention effect of broad leaved weed, expand herbicide controlling spectrum, reduce dosage, reduce cost accounting, improve to crop Security.

The content of the invention

It is an object of the invention to provide a kind of component rationally, drug cost is low, and significantly, herbicidal effect is good for synergistic effect, Preventing and treating spectrum is wide, to the ternary weeding composition containing pinoxaden of crop safety.

Another object of the present invention is to provide the ternary weeding composition preparation formulation containing pinoxaden.

It is still another object of the present invention to provide above-mentioned composition on preventing and treating cornfield gramineae weed and broad leaved weed Using.

In order to overcome the defect of existing unitary agent or two-spot compounding, the technical scheme of Herbicidal combinations of the present invention is so Solve：

A）First active component pinoxaden；

B）Second active component pyroxsulam；

C）One kind in 3rd active component fluorine chloropyridine ester or fluroxypyr.

First active component, the second active component are with the 3rd active component mass ratio（1~90）：（1~90）：（1~ 90）.

Specific embodiment

Pinoxaden, pyroxsulam, fluorine chloropyridine ester or fluroxypyr are illustrated below by Toxicity Determination In a kind of synergistic effect of compounding to cornfield gramineae weed and broad leaved weed.

In order to prevent and treat cornfield gramineae weed and broad leaved weed, we with pinoxaden, pyroxsulam and fluorine chloropyridine ester, Pinoxaden, pyroxsulam and fluroxypyr, have carried out the synergy research of mutual compounding respectively.Test method is referred to《In Magnificent people's republic's 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《NY/T1155.7-2006 agriculture of People's Republic of China's agricultural industry criteria The part of bioassay test criterion herbicide the 7th in coyote hole：The synergy of mixture is determined》.

Subjects are cornfield gramineae weed amur foxtail（Alopecurus aequalis）, Alopecurus （Alopecurus japonicus）, deceive grass（Beckmannia syzigachne）, hard grass（Sclerochloa dura）, it is black Wheat straw（Lolium perenne）；Broad leaved weed clearvers (Galium aparine）, chickweed（Stellaria media）, broadcast Ma wormwood artemisia（Descurainia sophia）, Veronica（Veronica didyma）.

The test medicine that active compound is configured to need, sets 5 various concentrations gradients by single dose and each compound drug first （Different according to dosages distribution on the basis of pilot study result, concentration gradient sets also different, prevent and kill off rate 5%~ Set by geometric progression in the range of 90%）.If clear water is compareed, it is repeated 4 times.Weeds were in for 2~3 leaf phases, from low dosage to agent high Amount carries out spraying treatment respectively.It is placed in after treatment and observation is cultivated in greenhouse, with the bottom infiltrating irrigation mode moisturizing of basin alms bowl.

The fresh weight preventive effect of each chemicals treatment is calculated within 21 days after treatment, by the probit value and the logarithm value of series concentration of preventive effect Between linear regression analysis, obtain the ED of each medicament₅₀Value, the co-toxicity coefficient of mixture is calculated with the abundant methods of Sun Yun（CTC）, come with this Evaluate activity of the reagent agent to weeds.

Co-toxicity coefficient CTC >=120 of complex preparation show as synergistic effect；CTC≤80 show as antagonism；80 ＜ CTC ＜ 120 show as summation action.
