Description
Technical field
The invention belongs to herbicide research and development technology field, particularly to a kind of Herbicidal combination containing flufenacet and bentazone
Thing and its application.
Background technology
Flufenacet (Flufenacet), molecular formula：C14H13F4N3O2S, chemical name：4`- fluoro- N- isopropyl -2- [5-
(trifluoro glycosides) -1,3,4- thiadiazole -2- imines] acetamide.Flufenacet is mainly played a role by suppressing cell division, mainly
For Semen Maydiss, Semen Tritici aestivi, Fructus Hordei Vulgaris, Soybean and Other Crops Tanaka annual gramineous weed such as Itanlian rye, and some broad-leaveds are miscellaneous
The before seedling after seedling early stage weeding of grass.
Bentazone, also known as Herba lysimachiae capillipedis pellet, bentazone, chemical name：3- isopropyl-(1H)-benzo -2,1,3- thiadiazine -4-
Ketone -2,2- dioxide, belong to benzothiadiazine type herbicides, its structural formula is：
Bentazone is inhibitor of photosynthesis, is that contact killing type has selective herbicide after seedling, for seedling stage cauline leaf process,
Worked by blade contact.Dry land uses, and first passes through blade face infiltration and is transmitted to inhibited photosynthesis in chloroplast.Bentazone
It is metabolised to weak the glycoconjugates of activity and detoxify, to crop safety in Semen Tritici aestivi body.After dispenser, 8-16 week bentazone is in soil
In can be decomposed by the microorganisms.
At present, corn field herbicide is limited by crop safety, and weed control spectrum is also limited, is used alone a kind of herbicide single dose
The generation of corn field weed can not completely effectively be controlled, furthermore some herbicides due to water solublity is big or the field lasting period too
Long, consumption is excessive or the uneven residual hazard all easily causing to this season crop or succession crop of dispenser.Therefore, present invention choosing
Select can weed control spectrum different, be made into mixture after the complementary flufenacet of pluses and minuses and the suitable decrement of two kinds of herbicides of bentazone and use,
So both expanding weed control spectrum hence it is evident that improve herbicidal effect, and it also avoid this season crop being produced with poisoning and to succession crop
Produce the probability of residual hazard.
Inventor it has been investigated that, the synergistic complex of herbicide is to expand weed control spectrum and improve effectively arranging of preventive effect
Apply, so far it is not yet found that closing the Herbicidal combinations that bentazone is compounded with flufenacet.
The information being disclosed in this background section is merely intended to increase the understanding of the general background to the present invention, and should not
Recognize when being considered or imply in any form that this information structure has been the prior art well known to persons skilled in the art.
Content of the invention
It is an object of the invention to provide a kind of for the Herbicidal combinations after maize seedling.
It is a further object of the present invention to provide application in cornfield weeding for this Herbicidal combinations.
To achieve these goals, the present invention is to employ the following technical solutions realization：
A kind of for the Herbicidal combinations after maize seedling, this Herbicidal combinations is with flufenacet and bentazone for effectively becoming
Point, flufenacet is 1-60 with the mass ratio of bentazone：1-60.
Preferably, described flufenacet is 1-40 with the mass ratio of bentazone：1-30.
Further preferably, described flufenacet and the mass ratio of bentazone are 1-59:1.
Most preferably preferred, described flufenacet is 12-59 with the mass ratio of bentazone:1.
In a preferred embodiment of the invention, flufenacet and bentazone are with 34:1、29:1、59:1、12:1 mass ratio
Compounding, Synergistic herbicidal effect can be produced.
In a preferred embodiment of the invention, flufenacet and bentazone are with 1:4、1:9、1:5、2:3.1、19:60、1:1
Mass ratio compound, considerable Synergistic herbicidal effect can be produced.
In the Herbicidal combinations of the present invention, flufenacet and both bentazones percent mass in Herbicidal combinations contains
Measure as 1-80%, preferred mass percentage composition is 30-65%.
In the binary built compositionss of the flufenacet of the present invention and bentazone, except flufenacet and bentazone etc. effectively
Outside composition, the auxiliary agents such as the conventional surfactants allowing, thickening agent, solvent or solid packing can also be added on pesticidal preparations and join
Any one dosage form allowing is made on pesticide.Preferably it is processed into cream, suspending agent, aqueous emulsion, microemulsion, water dispersible granular
Agent, wettable powder etc..
Herbicidal combinations of the present invention can be applied in corn field postemergence weed control, particularly wealthy in preventing and kill off corn field
In leaf weeds and sedge weed, application has remarkable result.
Compared with prior art, the present invention has the advantages 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 weeds
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.Bentazone has good preventive effect to sedge weed and most broad leaved weed,
Flufenacet can prevent and treat most of broad leaved weeds and part arbor section weeds.After both mixing, it is possible to increase miscellaneous to multiple broad-leaveds
The preventing and treating of grass.
(3) delay Weed Resistance.Herbicidal combinations of the present invention pass through binary built, reduce the resistance to medicament for the weeds, and
Improve the preventive effect of antagonism weeds, thus extending the service life of medicament.
(4) safe.Because its using dosage is under control, make medicament on the premise of improve drug effect, it is right
The safety of Semen Maydiss and succession crop is also improved.
(5) Herbicidal combinations of the present invention, are applied to corn field postemergence weed control, and it can prevent and kill off various broad-leaveds in corn field
Semen Maydiss and succession crop, on the premise of improve drug effect, are all had safety by weeds and sedge weed.
(6) Herbicidal combinations of the present invention can be applied in the herbicide for corn field postemergence weed control for the preparation, particularly
In preparation for preventing and kill off application in the herbicide of broad leaved weed and sedge weed in corn field.
