Abstract
The invention relates to a weeding composition containing carfentrazone-ethyl and clopyralid. The composition is mainly characterized by comprising 1-60 percent of carfentrazone-ethyl and 1-80 percent of clopyralid serving as active ingredients, an aid and other excipients and being prepared into wettable powder, water-dispersible granules, a suspending agent, a micro-emulsion, an aqueous emulsion and the like. The weeding composition is used for preventing and controlling wheatfield broadleaf weeds, gramineae weeds and sedges.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Herbicidal combinations that contains azoles humulone and clopyralid, be used to prevent and treat wheatland broad leaved weed, grassy weed and nutgrass flatsedge.
Background technology
Nineteen fifty-five has the people to report that Amrol can increase the prevent and kill off effect beginning of dalapon to the stone thatch, after, along with further developing of weed killer herbicide production and application, using with gradually between the weed killer herbicide grows up.China also comparatively payes attention to using with aspect the research of weed killer herbicide, is recognized extensively that to do be one of important measures of rationally using of weed killer herbicide, has worked out a series of Herbicidal compositions, has obtained bigger progress.
Azoles humulone (carfentrazone-ethyl), molecular formula: C

3, chemical name: ethyl-2-chloro-3-{2-chloro-5-[4-(difluoromethyl)-4,5-dihydro-3-methyl-5-oxygen-1H-1,2,4-triazol-1-yl]-4-fluorophenyl } and ethyl propionate.Clopyralid is the protoporphyrin oxidase inhibitor; Through suppressing the protoporphyrin oxidase; Thereby make film division. on cereal crop, use, be used for foliar treatment behind the seedling, responsive broad leaved weed conduction is obstructed and very fast withered dead. to wheat; Cereal crop safety such as corn. to having special efficacy, to succession crop safety in long-term weeds of using sulfonylureas weed killer herbicide area to develop immunity to drugs.
Clopyralid (clopyralid), molecular formula: C6H3Cl2NO2, molecular formula: 3,6-dichloropyridine-2-carboxylic acid.Clopyralid is a kind of auxin of synthetic, and its chemical constitution and many natural auxins are similar, but in the tissue of plant, has better persistence.It mainly the root through plant and leaf absorb then and in plant corpus, conduct, so its conductive performance is stronger.After the weeds dispenser, it is absorbed by blade of plant or root, in plant corpus, moves up and down and be transmitted to rapidly whole plant.Thereby the synthetic of DNA, RNA and protein that the clopyralid of low concentration can stimulating plant causes fissional out of control and unordered growth, causes tube bank being destroyed at last; The clopyralid of high concentration then can suppress the division and the growth of cell.
The chemical composition of each weed killer herbicide, structure and physicochemical property all are distinguishing.Therefore, they kill careless ability and scope is also different.It is narrower that some weed killer herbicide kills the grass spectrum, but have one's own knack, and can eradicate the weeds that are difficult to eliminate with other weed killer herbicide.
My company is devoted to the research and development of Herbicidal compositions.At present, do not appear in the newspapers with the relevant composite product of clopyralid about the azoles humulone.
Summary of the invention
The purpose of this invention is to provide a kind of Herbicidal combinations that contains the azoles humulone that is used for the wheat paddock control of weeds.
Technical scheme of the present invention is:
A kind of Herbicidal combinations that contains azoles humulone and clopyralid is characterized in that: Herbicidal combinations contains effective composition azoles humulone 1～60%, clopyralid 1～80%, auxiliary agent and other excipient surpluses.

Embodiment
Below in conjunction with embodiment the present invention is further explained.
Practice example one:
Azoles humulone and clopyralid are mixed to the active determination test report of wheat paddock weeds
Test objective: under the greenhouse pot culture condition, measured azoles humulone and clopyralid and different blended combo thereof and closed to broadcasting the herbicidal effect of ma's punt-pole; And estimated its synergy, for the formulation development and the agriculture chemical registration field control effectiveness test of Mixed Pharmacy provides scientific basis.
Supply the examination target: broadcast ma's punt-pole (Descurainia sophia (L.) Schur).
Test medicine: azoles humulone (carfentrazone-ethyl) 90% former medicine, clopyralid (clopyralid) 95% former medicine provides by Shaanxi Welch Crop Protection Co., Ltd..
The medicament configuration:
Azoles humulone solution: accurately take by weighing the former medicine of 0.0127g 90% azoles humulone,, add the clear water 400mL that contains the 0.1%TWEEN80 emulsifier, stir, be configured to azoles humulone 45g (a.i./hm with the 0.2mLDMF dissolving
2) solution, be diluted to 30g (a.i./hm with clear water again
2), 15g (a.i./hm
2) concentration is subsequent use.
Dichloropyridine acid solution: accurately take by weighing the former medicine of 0.0602g 95% clopyralid,, add the clear water 400mL that contains the 0.1%TWEEN80 emulsifier, stir, be configured to clopyralid 225g (a.i./hm with the 0.2mLDMF dissolving
2) solution, be diluted to 150g (a.i./hm with clear water again
2), 300g (a.i./hm
2) concentration is subsequent use.
Blank solution: 0.2mLDMF adds the water of 80mL 0.1%TWEEN80 emulsifier.
Test method: adopt potted plant cauline leaf facture (NY/T 1155.4-2006): the amount of setting soil in the polypots of high 6cm, diameter 9cm; To supply 15～20 sowings of examination target weed seed in polypots; Be placed on cultivation in the greenhouse after covering the thick fine earth of 0.5～1cm, treat that weeds grew to for 2～4 leaf phases and carry out cauline leaf spraying processing, every alms bowl spraying liquid 1mL; Every processing repetition 4 times, and establish the contrast that is treated to that does not contain medicament.Processing is placed in the greenhouse cultivates, the growing state of routine observation target weeds, and be injured symptom and growth inhibition situation of range estimation target behind the 15d, and claim acrial part fresh weight or strain fresh weight, estimate the toxicity action of medicament with form fresh weight inhibiting rate to the target weeds.
Investigation method:
Range estimation target be injured symptom and growth inhibition situation are handled behind the 15d in test, and claim to calculate fresh weight inhibiting rate (%) by the acrial part fresh weight.
The synergy evaluation method:
Estimate weed killer herbicide synergy mode (NY/T 1155.7-2006) according to the Gowing method, its formula is following:
E
0＝X+Y-XY/100
In the formula, X is that the azoles humulone is with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds; Y is that clopyralid is with the fresh weight inhibiting rate of certain dosage list time spent to the target weeds; E
0During for azoles humulone and two kinds of pharmacy mix of clopyralid to the theoretical value of target weeds fresh weight inhibiting rate; When E is azoles humulone and two kinds of pharmacy mix of clopyralid to the measured value of target weeds fresh weight inhibiting rate.
Evaluation criterion: work as E-E
0Be expressed as synergistic effect at＞10% o'clock, as-10%≤E-E
0Be expressed as summation action, and worked as E-E in≤10% o'clock
0Be expressed as antagonism at＜-10% o'clock.
Table 1 azoles humulone and clopyralid and the combination that is mixed thereof are to broadcasting the toxicity test result of ma's punt-pole
Table 1 azoles humulone and clopyralid and the combination that is mixed thereof are to broadcasting the toxicity test result of ma's punt-pole
Evaluating drug effect: azoles humulone and clopyralid and the composition that is mixed thereof are measured the result to the herbicidal effect of broadcasting ma's punt-pole and are seen table 1.It is thus clear that azoles humulone and clopyralid are mixed composition to broadcasting its E-E of ma's punt-pole grass with 15+150,15+225,15+300,30+150,30+225,30+300,45+150,45+225,45+300
