Abstract
The invention discloses a weeding composition containing triclopyr and simazine and application thereof. The weeding composition is prepared by taking the triclopyr and the simazine as main active ingredients, and the mass ratio of the triclopyr to the simazine is (1-70):(1-90). The weeding composition can be used for preparing an herbicide for weeding in woodland or noncropland. Compared with a single agent, the weeding composition has the advantages of broad weeding spectrum, long lasting period, safety for forests and succession crops, and obvious effects especially for controlling various grass, broadleaf weeds and weed small shrubs in the woodland or the noncropland.
Description
Technical field
The invention belongs to technical field of pesticide, especially the weed killer herbicide field relates to the binary built agent of Simanex and Triclopyr.This Herbicidal combinations can be applicable to forest land, uncultivated area weeding.
Background technology
Triclopyr (triclopyr), chemical name: 3,5,6-three chloro-2-pyridine 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 excess 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.Can be in soil rapidly by microbial decomposition.Be used for preventing and kill off the weeds and the shrub of 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 bigger 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 the weeds that remove in forest land and the uncultivated area and to improve safety, many and other herbicide mixtures of Triclopyr.
Simanex (simazine), chemical name: 2-chloro-4,6-two (ethylamino-)-1,3,5-triazines, its chemical formula is: C
7H
12ClN
5Simanex is interior suction selective herbicide, can be absorbed and conduct by plant root.Can prevent and kill off 1 year living broad leaved weed and part grassy weed, the lasting period is long.Can prevent and kill off 1 year living broadleaved herb such as green foxtail, india lovegrass, speedwell, nutgrass flatsedge, Siberian cocklebur, Eclipta prostrata, emarginate amaranth herb or seed, feather cockscomb, kitchen garden, grey dish, flowerofanhour root or herb, bluish dogbane, lady's-grass, yard grass, barnyard grass grass, convexutricle sedge herb, cyperus iria L. rhizoma scirpi, three-coloured amaranth, wolf's milk, acalypha copperleaf, lamb's-quarters and grassy weed.But Simanex is relatively poor to the perennial weed preventive effect, has restricted its application in forest land or uncultivated area weeding.
Forest land and uncultivated area weed killer herbicide are subjected to weeds big limit the in grass age at present, it is also limited to kill the grass spectrum, be used alone the agent of weed killer herbicide list and can not control the generation of forest land and uncultivated area weeds and undershrub completely effectively, moreover some weed killer herbicide is because water-soluble big or the field lasting period is oversize, consumption is excessive or the inhomogeneous residual hazard that all causes easily this season crop or succession crop of dispenser.Therefore, the present invention selects to kill grass spectrum difference, being made into mixture after two kinds of suitable decrements of weed killer herbicide of the Triclopyr of pluses and minuses complementation and Simanex uses, so both enlarged and killed the grass spectrum, obviously improved herbicidal effect, and controlled the generation of undershrub effectively, also avoided the too much residual poisoning of medicament to succession crop or interplanting crop.
Summary of the invention
The purpose of this invention is to provide a kind of Herbicidal combinations that contains Triclopyr and Simanex.
Another object of the present invention provides this Herbicidal combinations is used for the weed killer herbicide of forest land or uncultivated area weeding in preparation application.
A kind of Herbicidal combinations that contains Triclopyr and Simanex is characterized in that this Herbicidal combinations is main active ingredient with Triclopyr and Simanex, and wherein, the mass ratio of Triclopyr and Simanex is 1～70: 1～90.The mass ratio of preferred Triclopyr and Simanex is 1～50: 1～60.
In Herbicidal combinations, the two quality percentage composition in Herbicidal combinations of Triclopyr and Simanex is 1～85%, and the preferred mass percentage composition is 20～80%.Active ingredient of the present invention is present in the composition with the synergy effective dose.
In the binary built preparation of Triclopyr of the present invention and Simanex, except active ingredients such as Triclopyr and Simanex, 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 wetting powder, soluble powder, suspending agent, suspension emulsion, water dispersible granules, aqueous emulsion.Using said composition can adopt and 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. for use, and solvent can adopt ethylene glycol, cyclohexanone, dimethylbenzene, water etc.These auxiliary agents can singly be used or mixing and usefulness, also can add other auxiliary material that allows on the pesticidal preparations.
" % " of the present invention is weight percentage.
Herbicidal combinations 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 height.Triclopyr acts on metabolism of nucleic acid, and Simanex is interior suction selective herbicide, 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 broad leaved weed surely, and Simanex can be prevented and kill off broad leaved weed and part grassy weed, and after both mixed, herbicidal spectrum was wideer.
3, delay the weeds resistance.Herbicidal combinations of the present invention has different weeding mechanism, 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, Herbicidal combinations of the present invention can be used at the weed killer herbicide that preparation is used for forest land or uncultivated area weeding, particularly uses in preparation is used for preventing and kill off the weed killer herbicide of forest land or uncultivated area grass family, broad leaved weed and undershrub.
