Abstract
The invention discloses a herbicidal composition containing trifloxysulfuron and bentazone and application thereof. The herbicidal composition uses trifloxysulfuron and bentazone as effective ingredients having a mass ratio of 1-60:1-60. The herbicidal composition is useful in post-seedling weeding of sugarcane fields, particularly significant in preventing and removing broad-leaved weeds and cyperaceous weeds in sugarcane fields. Compared with a single agent, the herbicidal composition is higher in efficiency, can delay resistance of weeds, has wide herbicidal spectrum and long acting period, and is safe to both sugarcane 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 bentazone 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 Caulis Sacchari sinensis and Caulis Sacchari sinensis body, so that crop plant escapes injury.
Bentazone, has another name called Herba lysimachiae capillipedis pellet, bentazone, chemical name: 3-isopropyl-(1H)-benzo-2,1,3-thiadiazine-4-ketone-2,2-dioxide, belongs to benzothiadiazine type herbicides, structural formula:
Bentazone is inhibitor of photosynthesis, is that contact killing type has selective herbicide after seedling, processes for stem and leaf in seedling stage, worked by blade contact.Dry land uses, and first passes through blade face infiltration and is transmitted in chloroplast inhibited photosynthesis.Bentazone is metabolised to weak the glycoconjugates of activity in Semen Tritici aestivi body and detoxifies, to crop safety.After dispenser, 8-16 week bentazone can be decomposed by the microorganisms in soil.
Current sugarcane field herbicide 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 sugarcane field 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 bentazone, 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 bentazone.
It is a further object of the present invention to provide the application in sugarcane field weeding of this Herbicidal combinations.
A kind of Herbicidal combinations containing trifloxysulfuron Yu bentazone, it is characterized in that this Herbicidal combinations is with trifloxysulfuron and bentazone for effective ingredient, the mass ratio of trifloxysulfuron and bentazone is 1～60:1～60, the mass ratio of preferred trifloxysulfuron and bentazone is 1～40:1～30, it is preferred that the mass ratio of trifloxysulfuron and bentazone is 1:9～59:1, it is most preferred that the mass ratio of trifloxysulfuron and bentazone 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 bentazone, 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 bentazone, it is possible to produce considerable Synergistic herbicidal effect.
In Herbicidal combinations, trifloxysulfuron and both bentazones 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 bentazone, except the effective ingredient such as trifloxysulfuron and bentazone, 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 sugarcane field postemergence weed control, and particularly in preventing and kill off sugarcane field, in broad leaved weed and sedge 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.Sedge weed and most broad leaved weeds are had good preventive effect by bentazone, 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 Caulis Sacchari sinensis and succession crop be have also been obtained raising by it.
The Herbicidal combinations of the present invention, is applied to sugarcane field postemergence weed control, and it can prevent and kill off various broad leaved weeds and sedge weed in sugarcane field, under the premise that improve drug effect, Caulis Sacchari sinensis and succession crop is all had safety.
Therefore, Herbicidal combinations of the present invention can be applied in the preparation herbicide for sugarcane field postemergence weed control, particularly applies in the herbicide of broad leaved weed and sedge weed for preventing and kill off in sugarcane field in preparation.
