Background technology
Hexazinone (hexazinone), is interior suction selective herbicide, and plant roots, leaf can absorb, mainly by wooden
Portion conducts, and pine tree root is not injured, is excellent woods herbicide.Drug effect process is slower, weeds 1 month, 2, shrub
Month, arbor 3-10 month.Hexazinone is applied to evergreen coniferous forest, the such as tending ot young growth such as Korean pine, pinus sylvestris var. mongolica, cloud shirt, masson pine.Make
Before woods weeding go out filling, safeguard forest fire protection line and stand conversion etc., most of unifacial leaf and broadleaf weed and woody can be prevented and kill off
Plant chrysanthemum honeysuckle, false spiraea, fibert, willow leaf meadow sweet, wilsonii, aspen, wooden birch, linden, Manchurian ash, Amur cork-tree, walnut are seized
Deng.
Bentazone, also known as Lysimachia sikokiana pellet, Bentazon, chemical name：3- isopropyls-(1H)-benzo -2,1,3- thiadiazine -4-
Ketone -2,2- dioxide belong to benzothiadiazine type herbicides, and its structural formula is：
Bentazone is inhibitor of photosynthesis, is the selective herbicide after seedling of contact killing type, for seedling stage cauline leaf process,
Worked by blade contact.Dry land is used, and is first passed through blade face infiltration and is transmitted to inhibited photosynthesis in chloroplaset.Bentazone
Weak the glycoconjugates of activity is metabolized as in wheat body and is detoxified, to crop safety.After dispenser, 8-16 week bentazones are in soil
In can be decomposed by the microorganisms.
At present, sugarcane field herbicidal is limited by crop safety, and weed control spectrum is also limited, and a kind of herbicide single dose is used alone
Can not completely effectively control the generation of sugarcane field weed, furthermore some herbicides due to the water-soluble big or field lasting period too
Long, consumption is excessive or the uneven residual hazard all easily caused to this season crop or succession crop of dispenser.Therefore, present invention choosing
Select can weed control spectrum it is different, be made into mixture use after the complementary hexazinone of pluses and minuses and the appropriate decrement of two kinds of herbicides of bentazone, this
Sample had both expanded weed control spectrum, hence it is evident that improve herbicidal effect, it also avoid producing this season crop poisoning and succession crop is produced
The possibility of raw residual hazard.
The information for being disclosed in the background section is merely intended to increase the understanding of the general background to the present invention, and should not
When the prior art for being considered to recognize or imply the information structure in any form well known to persons skilled in the art.
The content of the invention
It is an object of the invention to provide a kind of Herbicidal combinations for sugarcane after seedling.
It is a further object of the present invention to provide application of the Herbicidal combinations in sugarcane field weeding.
To achieve these goals, the present invention is to employ the following technical solutions realization：
A kind of Herbicidal combinations for sugarcane after seedling, it is effective with hexazinone and bentazone that described Herbicidal combinations are
Composition, hexazinone are 1-60: 60-1 with the mass ratio of bentazone.
Preferably, the described Herbicidal combinations for sugarcane after seedling, in described Herbicidal combinations hexazinone with go out
The mass ratio of careless pine is 1-30：30-1.
Present invention also offers a kind of pesticidal preparations, containing the described Herbicidal combinations for sugarcane after seedling, hexazinone
Weight/mass percentage composition with both bentazones in Herbicidal combinations is 1-80%, remaining be allow in agricultural chemicals the auxiliary that uses into
Point.
Preferably, described pesticidal preparations, quality percentage of the hexazinone with both bentazones in Herbicidal combinations contains
Measure as 30-65%, remaining is the auxiliary element for allowing in agricultural chemicals to use.
Preferably, described formulation is missible oil, suspending agent, aqueous emulsion, microemulsion, water dispersion granule or wettable powder
Agent.
Present invention also offers described Herbicidal combinations or described pesticidal preparations are preparing sugarcane field postemergence weed control
Application in herbicide.
Present invention also offers the described Herbicidal combinations or described pesticidal preparations broad-leaved in sugarcane field is prevented and kill off in preparation
Application in the herbicide of weeds and/or sedge weed.
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 weeds,
Hexazinone can prevent and treat most of broad leaved weeds and part arbor section weeds.After both mixing, it is possible to increase to various broad leaved weeds
Preventing and treating.
(3) delay Weed Resistance.Herbicidal combinations of the present invention reduce resistance of the weeds to medicament by binary built, and
The preventive effect of antagonism weeds is improved, so as to extend the service life of medicament.
