Abstract
The invention discloses a synergistic herbicide composition containing triclopyr and hexazinone and application thereof. In the herbicide composition, the triclopyr and the hexazinone are taken as the main active ingredients; and the mass ratio of the triclopyr to the hexazinone is 1-75: 1-75. The herbicide composition can be used for preparing herbicide for killing weeds in a woodland or non-cultivated land. Compared with single-composition herbicide, the herbicide composition has a broad herbicide spectrum and acts for a long time on the premise of improving herbicide effect, is safe for the forests and the afterculture crops, and particularly has an obvious effect of controlling various graminaccae, broadleaf weeds and undershrub in the woodland or the non-cultivated land.
Description
Technical field
The invention belongs to technical field of pesticide, especially the weed killer herbicide field relates to the binary built agent of Triclopyr and hexazinone.This Herbicidal combinations can be applicable to forest land, uncultivated area weeding.
Background technology
Triclopyr (triclopyr), chemical name: 3,5,6-three Chloro-2-Pyridyle fluoroacetic acid, its chemical formula is: C
7H
4Cl
3NO
3
Triclopyr is a kind of translocated herbicide, acts on metabolism of nucleic acid, makes plant produce excessive nucleic acid, make some structural transformations become meristematic tissue, cause blade, stem and root growth deformity, reserve substance exhausts, the vascular bundle tissue is by embolism or break, and plant is dead gradually.In soil, can be decomposed by microorganism rapidly.For weeds and the shrub of preventing and kill off forest land and uncultivated area, as: alternanthera philoxeroides, Veronica, fern, Eupatorium adenophorum, abrotanum etc.But the Triclopyr herbicidal spectrum is single, and is invalid to grassy weed, in addition, it is larger in pedo relict, and a pair of second stubble crop or interplanting in woodland crop are shone into poisoning, therefore, in order thoroughly to kill except the weeds in forest land and the uncultivated area and to improve safety, many and other herbicide mixtures of Triclopyr.
Hexazinone (hexazinone), chemical name: 3-cyclohexyl-6-(dimethylamino)-1-methyl isophthalic acid, 3,5-triazine-2,4-(1H, 3H)-diketone, its chemical formula is: C
12H
20N
4O
2Hexazinone is interior suction selective herbicide, mainly suppresses photosynthesis of plant, and plant roots, leaf can both absorb, and mainly by the xylem conduction, makes metabolic disorder, causes death.To the not injury of pine tree root, it is good woods weed killer herbicide.Be applicable to evergreen softwood forest, such as tending [after young plantations such as Korean pine, pinus sylvestris var. mongolica, dragon spruce, masson pines.Before the afforestation weeding go out filling, safeguard forest fire protection line and stand improvement etc., can prevent and kill off most of unifacial leaf and broadleaf weed and woody plant chrysanthemum honeysuckle, false spiraea, fibert, willow leaf meadow sweet, wilsonii, aspen, wooden birch, linden, Manchurian ash, yellow POLO, walnut and seize etc.But hexazinone drug effect process is slower, weeds 1 month, shrub 2 months, arbor 3-10 month.Therefore, seriously restricted the use of this medicament.
Forest land and uncultivated area weed killer herbicide are subjected to weeds large limit the in grass age at present, the herbicide spectrum is also limited, be used alone the weed killer herbicide single dose and can not control completely effectively the generation of forest land and uncultivated area weeds and undershrub, moreover some weed killer herbicide is because water-soluble large or the field lasting period is oversize, consumption is excessive or the inhomogeneous residual hazard that all easily causes this season crop or succession crop of dispenser.Therefore, but selection herbicide spectrum of the present invention is different, being made into mixture after two kinds of suitable decrements of weed killer herbicide of the Triclopyr of pluses and minuses complementation and hexazinone uses, so both enlarged the herbicide spectrum, obviously improved herbicidal effect, and effectively controlled the generation of undershrub, also avoided the too much residual poisoning to succession crop or interplanting crops of medicament.
Summary of the invention
The purpose of this invention is to provide a kind of Synergistic herbicide compositions that contains Triclopyr and hexazinone.
Another object of the present invention provides this Herbicidal combinations for the preparation of the application in the weed killer herbicide of forest land or uncultivated area weeding.
A kind of Synergistic herbicide compositions that contains Triclopyr and hexazinone is characterized in that this Herbicidal combinations take Triclopyr and hexazinone as main active ingredient, and the mass ratio of Triclopyr and hexazinone is 1～75: 1～75.The mass ratio of preferred Triclopyr and hexazinone is 1～40: 1～55, most preferably 1～30: 1～30.
In Synergistic herbicide compositions, the two quality percentage composition in Herbicidal combinations of Triclopyr and hexazinone is 1～85%, and the preferred mass percentage composition is 10～80%, and most preferably the quality percentage composition is 30～80%.
In the binary built preparation of Triclopyr of the present invention and hexazinone, except the active ingredients such as Triclopyr and hexazinone, can also add the auxiliary agents such as conventional surfactants, thickener, solvent or solid packing that allow on the pesticidal preparations and be mixed with any one formulation that allows on the agricultural chemicals.Preferably be processed into suspending agent, wetting powder, soluble powder, soluble liquid, water dispersible granules, granule, missible oil etc.Can adopt when using and the conventional known method such as spray.
Described surfactant specifically can adopt alkylphenol polyoxyethylene, phenethyl phenol polyethenoxy ether, methyl naphthalene sulfonate formaldehyde condensate, polyoxyethylene nonylphenol ether, NNO (di-2-ethylhexylphosphine oxide bitter edible plant sodium sulfonate) etc., solid packing can be selected kaolin, diatomite etc., and solvent can adopt ethylene glycol, cyclohexanone, dimethylbenzene, water etc.These auxiliary agents can alone or mixing and usefulness, also can add other auxiliary material that allows on the pesticidal preparations.
" % " of the present invention is weight percentage.
Synergistic herbicide compositions of the present invention can be used in forest land or uncultivated area postemergence weed control, particularly uses in various grass family, broad leaved weed and the undershrub to have remarkable result in preventing and kill off forest land or uncultivated area.
Herbicidal combinations of the present invention has the following advantages:
1, activity of weeding is high.Triclopyr acts on metabolism of nucleic acid, and hexazinone mainly is inhibited photosynthesis, that is to say, Herbicidal combinations of the present invention can kill weeds by two kinds of different modes, can greatly improve the removing activity of Herbicidal combinations.
2, herbicidal spectrum is wide.Greenweed is prevented and kill off grass family, broad leaved weed and undershrub surely, and hexazinone can be prevented and kill off various weeds and some woody plants, and after both mixed, herbicidal spectrum was wider.
3, delay Weed Resistance.Herbicidal combinations of the present invention has different mechanisms, can prevent and treat various resistant weeds, and delays weeds generation resistance, prolongs the service life of medicament.
4,, safe.Herbicidal combinations of the present invention is applied to forest land or uncultivated area weeding, and it can prevent and kill off various grass family, broad leaved weed and undershrub in forest land or the uncultivated area, and under the prerequisite that has improved drug effect, its safety to forest and succession crop also is improved.
Therefore, Synergistic herbicide compositions of the present invention can be used in the weed killer herbicide for the preparation of forest land or uncultivated area weeding, is particularly using in the weed killer herbicide in grass family, broad leaved weed and the undershrub for the preparation of preventing and kill off in forest land or the uncultivated area.
