Abstract
The invention discloses an herbicidal composition with trifloxysulfuron and fenoxaprop-p-ethyl and application thereof.The herbicidal composition uses trifloxysulfuron and fenoxaprop-p-ethyl as effective ingredients, having a weight ratio of 1-60:1-60.The herbicidal composition is useful in post-seedling weeding of cotton fields and is particularly significantly effective in controlling grassy weeds and broad-leaved weeds in cotton fields.Compared with single agents, the herbicidal composition enables improved efficacy, delayed resistance in weeds, broad weeding spectrum and long lasting period and is safe to both cotton and afterculture crops.
Description
Technical field
The invention belongs to technical field of pesticide, especially herbicide field, be specifically related to a kind of Herbicidal combinations containing trifloxysulfuron with fenoxapropPethyl and application thereof.
Background technology
Trifloxysulfuron, has another name called Ying Feite.Chemical name: 1-(4,6-dimethoxypyridin-2-base)-3-[3-(2,2,2-trifluoro ethoxy)-2-pyridine sulfonyl sulfonyl] urea, structural formula is:
Trifloxysulfuron belongs to sulfonylurea herbicide, can be absorbed by the root of weeds, stem, leaf after dispenser, downwardly and upwardly can conduct in plant, by suppressing the activity of acetolactate synthestase (ALS), thus affecting the biosynthesis of branched-chain amino acid (such as leucine, isoleucine, valine etc.).Showing as growing point necrosis, vein chlorosis after hazard of plant, plant growing is heavily suppressed, dwarfing, and final Herb is withered.Trifloxysulfuron is to difference mainly due to katabolism of the selectivity of weeds and crop.It can be inactive material by rapid metabolization in Cotton Gossypii and Caulis Sacchari sinensis body, so that crop plant escapes injury.
FenoxapropPethyl, has another name called fat horse, prestige despot, chemical name: (R)-2-[4-(6-chloro-2-benzothiazole oxygen base) phenoxy group] ethyl propionate, belongs to aryloxy carboxylic acid herbicide, structural formula:
FenoxapropPethyl acetyl-CoA carboxylase (ACCase) inhibitor.FenoxapropPethyl belongs to stem and leaf inorganic agent after selectivity, inner sucting conduction type Seedling.Effective ingredient is transmitted to the growing point of phyllopodium, internode separate living tissue, root after being absorbed by stem and leaf, rapidly transform into the free acid of phenoxy group, it is suppressed that fatty acid carries out biosynthesis, damages weed growth point, separate living tissue.Effect rapidly, stops growing in 2-3d after dispenser, 5-7d lobus cardiacus chlorosis purpling color, separate living tissue browning, and then tiller base portion is downright bad, and blade purpling is withered gradually.Drug resistance crop resolves into inactive metabolite and detoxifies.
Current weeding in cotton field agent is limit by crop safety, herbicide spectrum is also limited, it is used alone a kind of herbicide single dose and can not control the generation of Cotton Fields weeds completely effectively, furthermore some herbicide is owing to water solublity is big or the field lasting period is oversize, consumption is excessive or the uneven residual hazard all easily caused this season crop or succession crop of dispenser.Therefore, the present invention selects herbicide to compose difference, it is made into mixture use after the trifloxysulfuron of pluses and minuses complementation and two kinds of suitable decrements of herbicide of fenoxapropPethyl, so both expand herbicide spectrum, significantly improve herbicidal effect, it also avoid and this season crop is produced poisoning and succession crop is produced the probability of residual hazard.
Summary of the invention
It is an object of the invention to provide a kind of Herbicidal combinations containing trifloxysulfuron Yu fenoxapropPethyl.
It is a further object of the present invention to provide the application in weeding in cotton field of this Herbicidal combinations.
A kind of Herbicidal combinations containing trifloxysulfuron Yu fenoxapropPethyl, it is characterized in that this Herbicidal combinations is with trifloxysulfuron and fenoxapropPethyl for effective ingredient, the mass ratio of trifloxysulfuron and fenoxapropPethyl is 1～60:1～60, the mass ratio of preferred trifloxysulfuron and fenoxapropPethyl is 1～40:1～30, it is preferred that the mass ratio of trifloxysulfuron and fenoxapropPethyl is 1:9～59:1, it is most preferred that the mass ratio of trifloxysulfuron and fenoxapropPethyl is 12～59:1.
In a preferred embodiment of the invention, trifloxysulfuron is composite with the mass ratio of 34:1,29:1,59:1,12:1 with fenoxapropPethyl, it is possible to produce Synergistic herbicidal effect.
In a preferred embodiment of the invention, trifloxysulfuron is composite with the mass ratio of 1:4,1:9,1:5,2:3.1,19:60,1:1 with fenoxapropPethyl, it is possible to produce considerable Synergistic herbicidal effect.
In Herbicidal combinations, trifloxysulfuron and both fenoxapropPethyls weight/mass percentage composition in Herbicidal combinations are 1～80%, it is preferable that weight/mass percentage composition is 30～65%.
In the binary built compositions of the trifloxysulfuron of the present invention and fenoxapropPethyl, except the effective ingredient such as trifloxysulfuron and fenoxapropPethyl, it is also possible to add any one dosage form that the auxiliary agents such as the conventional surfactants, thickening agent, solvent or the solid packing that allow on pesticidal preparations are configured on pesticide to allow.Preferably it is processed into cream, suspending agent, aqueous emulsion, microemulsion, water dispersion granule, wettable powder etc..
Herbicidal combinations of the present invention can be applied in Cotton Fields postemergence weed control, and particularly in preventing and kill off Cotton Fields, in grass family and broad leaved weed, application has remarkable result.
" % " that do not make specified otherwise in the present invention all represents mass percent.
The Herbicidal combinations of the present invention has the advantage that
1, activity of weeding is high.The Herbicidal combinations of the present invention can kill weeds by two kinds of different mechanism so that Weed Resistance produces speed and reduces, and is greatly enhanced the removing activity of herbicide.
2, herbicidal spectrum is wide, and the lasting period is long.Grassy weed is had good preventive effect by fenoxapropPethyl, and trifloxysulfuron can prevent and treat most of broad leaved weed and part arbor section weeds.After both mixing, it is possible to increase the preventing and treating to multiple broad leaved weed.
3, Weed Resistance is delayed.Herbicidal combinations of the present invention passes through binary built, the reduction weeds resistance to medicament, and improves the preventive effect of antagonism weeds, thus extending the service life of medicament.
4, safety is high.Owing to its using dosage is under control, making medicament under the premise that improve drug effect, the safety of Cotton Gossypii and succession crop be have also been obtained raising by it.
The Herbicidal combinations of the present invention, is applied to Cotton Fields postemergence weed control, and it can prevent and kill off grassy weed and various broad leaved weed in Cotton Fields, under the premise that improve drug effect, Cotton Gossypii and succession crop is all had safety.
Therefore, Herbicidal combinations of the present invention can be applied in the preparation herbicide for Cotton Fields postemergence weed control, particularly applies in the herbicide of grassy weed and broad leaved weed for preventing and kill off in Cotton Fields in preparation.
