Abstract
The invention discloses a kind of mixed herbicide containing careless ammonium phosphine, picloram and Triclopyr, wherein, be decided to be active ingredient with careless ammonium phosphine, picloram and greenweed, the mass ratio of careless ammonium phosphine, picloram and Triclopyr is 5～50:5～50:10～20. Mixed herbicide of the present invention can be used for forest land or bare place weeding, particularly has remarkable result in the application of preventing and kill off forest land or bare place kind undershrub, grassy weed and broad leaved weed. Herbicide of the present invention having improved under the prerequisite of drug effect, delays Weed Resistance with respect to single dose, and herbicidal spectrum is wide, and the lasting period is long.
Description
Technical field
The invention belongs to technical field of pesticide, especially herbicide field, relates to three of careless ammonium phosphine, picloram and TriclopyrUnit's built agent. This herbicidal composition can be applicable to forest land, bare place weeding.
Background technology
Picloram (Picloram), chemical name: 4-amino-3,5,6-trichloropyridine carboxylic acid, structural formula is as follows:
Picloram is a kind of interior suction, selective herbicide, has plant growth regulation, and Main Function is in nucleic acid generationThank, and make greenery body structure and other organelle developmental deformities, interferencing protein is synthetic, acts on separate living tissue activity etc.,Finally cause plant death, be mainly used in cornfield herbicidal, harmful to most of broad leaf crops, in the time of crop rotation, consider residualStay the impact of picloram to broad leaf crop (beans, cotton, vegetables, tobacco etc.), therefore, in use, be subject to certain limitation.
Grass ammonium phosphine (Glufosinate), molecular formula: C5H15N2O4P, chemical name: (RS)-2-amino-4-(hydroxyl methoxyThe base of seeing) butyric acid ammonium, its structural representation is as follows:
Grass ammonium phosphine is glutamine synthetase inhibitor, is non-selective contact weedicide, can be used for forest land bare place and prevents and kill offAnnual and perennial dicotyledonous and grassy weed. As mouse tail amur foxtail, lady's-grass, barnyard grass, wild barley, Itanlian rye, dog tailGrass, setaria glauca, wild wheat, wild corn, orchard grass, bent awns hairgrass, fescue grass, black nightshade, chickweed, field scorpion grass, quackgrass, crawlCrawl bent grass, Calamagrostis epigejos, sedge, Bermuda grass, Amaranthus retroflexus etc., prevent and kill off broad leaved weed and should, in the vigorous growth phase dispenser of beginning, prevent and kill off standing grainUndergraduate course weeds should be in dispenser in tillering stage. But careless ammonium phosphine cannot kill except the undershrub in forest land or bare place, in addition, partWeeds have produced resistance to careless ammonium phosphine. Make its use in forest land and bare place be subject to certain limitation.
Triclopyr (Triclopyr), molecular formula:: C7H4Cl3NO3, chemical name: 3,5,6-tri-Chloro-2-Pyridyle fluoroacetic acid,Its structural representation is as follows:
Triclopyr is a kind of translocated herbicide, and effect nucleic acid metabolism, makes plant produce excessive nucleic acid, makes some tissuesBe transformed into separate living tissue, cause blade, stem and root growth deformity, reserve substance exhausts, and vascular bundle tissue is by embolism or break, and plantsStrain is dead gradually. In soil, can be decomposed by microorganism rapidly. For preventing and kill off weeds and the shrub of forest land and bare place kind, as skyHeart alternanthera, Veronica, fern, Eupatorium adenophorum, abrotanum etc. But Triclopyr herbicidal spectrum is single, invalid to grassy weed, thisOutward, it is larger in pedo relict, easily second stubble crop or interplanting in woodland crop is caused to poisoning, therefore, and in order thoroughly to kill except forest landAnd weeds in bare place and improve security, many and other herbicide mixtures of Triclopyr.
In forest land and bare place, except containing various weeds, also there are the various undershrubs of a large amount of self-sows, oneAs in situation, weed growth is luxuriant, robust plant, and various overgrown with bushes keeps the sun off, contention nutrient is still, currentHerbicide can not be controlled the generation of forest land and bare place weeds and undershrub completely effectively, and artificial weeding cost is high, effectRate is low, has brought very large difficulty to the weeds control of forest land and bare place. Therefore, the present invention selects herbicide to compose different, excellent scarceAfter putting complementary careless ammonium phosphine, picloram and the suitable decrement of all herbicides of Triclopyr three, be made into mixture use, both expanded like thisHerbicide spectrum, has obviously improved herbicidal effect, and has effectively controlled the generation of undershrub.
Summary of the invention:
The object of the invention is to overcome above-mentioned weak point, a kind of ternary containing careless ammonium phosphine, picloram and Triclopyr is providedMixed herbicide.
Another object of the present invention is to provide this herbicide and is preventing and kill off various weeds and shrub for forest land or bare placeApplication.
The object of the invention is to realize in the following manner:
Containing a mixed herbicide for careless ammonium phosphine, picloram and Triclopyr, this herbicide is with careless ammonium phosphine, picloram and greenweedBe decided to be main active ingredient, wherein, the mass ratio of careless ammonium phosphine, picloram and Triclopyr is 5～50:5～50:10～20.
Above-mentioned careless ammonium phosphine, picloram are 1～6:1～6:1～6 with Triclopyr preferred mass ratio.
The most preferably mass ratio of above-mentioned careless ammonium phosphine, picloram and Triclopyr is 1～6:1～2:2～3.
Mixed herbicide of the present invention, is decided to be and mainly contains on effect composition and agricultural chemicals with careless ammonium phosphine, picloram and greenweedThe auxiliary agent (as conventional surfactants, solid packing) allowing is mixed with any one formulation allowing on agricultural chemicals, preferably processingBecome soluble granule, solvable pulvis, wettable powder and water dispersible granules.
Grass ammonium phosphine, picloram and the gross mass percentage composition of Triclopyr three in herbicide are 30～90%.
Preferred careless ammonium phosphine, picloram and the gross mass percentage composition of Triclopyr three in herbicide are 50～80%.
In above-mentioned mixed herbicide, Triclopyr and picloram can sour forms or ammonium salt, ethanolamine salt, triisopropanolamineAny one form such as salt, triethylamine salt adds (its active constituent content is in corresponding Triclopyr or picloram). Grass ammonium phosphineCan sour form or any one form such as ammonium salt, sodium salt or sylvite add (its active constituent content is in careless ammonium phosphine).
Mixed herbicide of the present invention can be applied in forest land or bare place postemergence weed control, is particularly preventing and kill off forest landOr in bare place in various weeds and undershrub application there is remarkable result.
Herbicidal composition of the present invention has the following advantages:
1, herbicide activity of weeding of the present invention is high. Herbicidal composition of the present invention can kill by three kinds of different mechanismWeeds, make Weed Resistance produce Speed Reduction, greatly improve the removing activity of herbicide.
2, herbicide broad weed-killing spectrum of the present invention. After three mixes, herbicidal spectrum almost bedding whole farmland weed, and rightUndershrub has special efficacy.
3, herbicide preparation technology of the present invention is simple, is convenient to large-scale production. When the present invention adds active ingredient, both canBeing acid, as Triclopyr acid and picloram acid, can be also the various water soluble salt forms such as ammonium salt, ethanolamine salt, can basisHandling characteristics and formulation need to select, and have and process the advantages such as flexible.
