Abstract
The invention discloses a weeding composite with synergized action and is characterized in that the effective components are carfentrazone-ethyl and clodinafop-propargyl and the weight ratio of carfentrazone-ethyl to clodinafop-propargyl is 40:1-1:20. The combination of carfentrazone-ethyl and clodinafop-propargyl plays an action of synergized action and can expand effective control spectrum. Theweeding composite with synergized action of the invention can be used for preventing and killing off various weeds in wheat fields.
Description
Technical field
The present invention relates to a kind of Herbicidal combinations, be specially the Herbicidal combinations that contains active component azoles humulone and alkynes oxalic acid with synergistic effect, and the application of said composition in the wheat paddock weed control.
Background technology
Farmland weed and the crops liquid manure that wins honour for also is the important place of hiding, lodge of damage by disease and insect, brings about great losses to agricultural production.At present, carrying out chemical weed control with weed killer herbicide is the important means that wheat weeds is prevented and kill off.But, in the existing weed killer herbicide, some kinds are only effective to broadleaf weed, and it is relatively poor to the monocotyledon weed preventive effect, as 2,4-d butyl ester, tribenuron-methyl, methyl Erhuang are grand etc., and some kinds are only to monocotyledon weed preventive effect height, and relatively poor to the broad leaved weed preventive effect, as fenoxapropPethyl, alkynes oxalic acid, nicosulfuron, rimsulfuron etc.
The azoles humulone, the trade name spirit of going out soon, English common name Carfentrazone-ethyl, chemical name is ethyl-2-chloro-3-(2-chloro-5-(4-(difluoromethyl)-4,5-dihydro-3-methyl-5-oxygen-1H-1,2,4 triazol-1-yls)-and the 4-fluorophenyl) ethyl propionate), belong to the triazolineone systemic herbicide, be applicable to that wheat paddock, corn field and paddy field prevent and kill off broad leaved weed and nutgrass flatsedge, the weeds that sulfonylurea herbicide produced resistance have very high activity.Its mechanism of action is for proporphyrinogen oxidase causes that cell membrane destroys in the chlorophyll biosynthetic process by suppressing, and makes blade withered, dead rapidly.It is fast to be characterized in killing careless speed, and medication 3-4 days weeds are all dead under suitable temperature.But its weeding scope is narrower, the lasting period short, can not effectively prevent and kill off the part grassy weed.
Alkynes oxalic acid has another name called alkynes grass ester, and English common name Clodinafop-propargyl belongs to fluorine-containing phenoxy carboxylic acid high-efficiency low-toxicity weed killer herbicide, and is effective especially to pernicious grassy weed.Have low temperature resistant, resistance of rainwater washing against, operating period limit for width, to characteristics such as wheat and succession crop safety.Be used for cereal crop field control grassy weed, as mouse tail amur foxtail, wild oat, perennial ryegrass, annual bluegrass, green foxtail, caput grass etc.But to the anti-heterodyne of wheat paddock broad leaved weed.
Summary of the invention
The purpose of this invention is to provide a kind of wheat paddock Synergistic herbicide compositions that is used for, can effectively prevent and kill off broad leaved weed and grassy weed.
Technical scheme:
A kind of Herbicidal combinations is characterized in that: active ingredient is azoles humulone and alkynes oxalic acid, and the mass ratio of azoles humulone and alkynes oxalic acid is 40: 1-1: 20.
Described Herbicidal combinations, the former medicine that employing contains active ingredient adds auxiliary agent and excipients to be made agricultural according to production technology well known by persons skilled in the art and goes up operable any formulation, and preferred formulation comprises wetting powder, water dispersible granules, suspending agent and oil-suspending agent.
Described Herbicidal combinations, wherein the active ingredient total content is 5%-80%.
As to a kind of improvement of the present invention, the mass ratio of azoles humulone and alkynes oxalic acid is 7 in the composition: 1-1: 8.
Beneficial effect of the present invention is: 1, azoles humulone and alkynes oxalic acid are composite, have synergistic effect, reduce effective ingredient consumption, reduce environmental pollution; 2, the expanding prevention spectrum can be prevented and kill off broadleaf weed and monocotyledon weed simultaneously, reduces the control cost; 3, improve quick-acting, prolong the lasting period.
Embodiment
The present invention is further described below in conjunction with embodiment, but can not be considered as limiting the present invention.

(2) joint toxicity measuring of the present composition and field control effectiveness test
1, joint toxicity measuring
For trying weeds: the monocotyledon weed-grass family Avena wild oat (Avena fatua L) and the broadleaf weed-Rubiaceae Bedstraw clearvers (Galium aparinevar.tenerum (Gren.et Godr.) Rchb) that are collected in area just outside a city gate town, Suixian County, Henan Province winter wheat field.
Test medicine: the different proportioning medicaments of enumerating in the azoles humulone, alkynes oxalic acid and the embodiment of the invention.
Assay method: indoor pot method.Handle in wild oat tri-leaf period, the spraying of clearvers cauline leaf in seedling stage; 750 liters/hectare of the water yields are converted in spraying, and measurement result is the weeds fresh weight of living, and every processing repeats for five times, adopt the Colby method to judge the synergy type.
Colby law theory preventive effect computing formula is:
E
0＝XY/100
E in the formula
0Be single agent A and the B theoretical preventive effect after using with; X is that weed killer herbicide A weeds weight under certain dosage is the percentage of contrast weeds weight; Y is that weed killer herbicide B weeds weight under certain dosage is the percentage of contrast weeds weight; If being A, B, E uses the percentage of the weeds weight of back actual measurement with for contrast weeds weight.If E is significantly less than E
0, then be synergistic effect; E and E
0, approaching, then be summation action; E is obviously greater than E
0, then be antagonism.
Result of the test:
The composite joint toxicity measuring of table 1 azoles humulone and alkynes oxalic acid different proportion to wild oat and clearvers
The result of the composite co-toxicity test of azoles humulone and alkynes oxalic acid shows that azoles humulone and alkynes oxalic acid are 40: 1-1: in 20 the ratio range, wild oat and clearvers are had synergistic effect.
2 field trials
Field trial and on March 12nd, 2008 carry out at area just outside a city gate town, Suixian County, Henan Province winter wheat field.Sub-district area 20m
2, three repetitions, the sampling area is 1m
2Monocotyledon weed and broadleaf weed strain number in the investigation sample prescription are sprayed by the consumption of experimental scheme then, 15 days " Invest, Then Investigate " survival strain numbers.Reagent agent is different proportioning medicaments in the embodiment of the invention and 40% azoles humulone water dispersible granules (FMC), 15% alkynes oxalic acid wetting powder (just reaching earlier).Result of the test is as follows:
The different compound proportions with alkynes oxalic acid of table 2 azoles humulone are to the preventive effect of wheat paddock weeds
