Abstract
The invention discloses a glufosinate-aryloxyphenoxypropionic acid herbicide weeding composition. The glufosinate-aryloxyphenoxypropionic acid herbicide weeding composition comprises glufosinate and an aryloxyphenoxypropionic acid herbicide as active ingredients, and the balance pesticide assistants. A weight ratio of glufosinate to the aryloxyphenoxypropionic acid herbicide in the glufosinate-aryloxyphenoxypropionic acid herbicide weeding composition is in a range of (50: 1) to (1: 1). The glufosinate-aryloxyphenoxypropionic acid herbicide weeding composition comprises 10 to 80wt% of glufosinate and the aryloxyphenoxypropionic acid herbicide. The glufosinate-aryloxyphenoxypropionic acid herbicide weeding composition can be used for preventing and removing weeds in bare places, orchards and field ridges, has effects superior to effects of a single aryloxyphenoxypropionic acid herbicide or glufosinate, reduces a use amount of a pesticide, reduces the adverse influence produced by a pesticide on the ecological environment, and effectively solves the problem of weed resistance to pesticides.
Description
Technical field
The present invention relates to a kind of Herbicidal combinations, is take careless ammonium phosphine and aryloxy group phenoxy propionic acid compounds as active ingredient, is used for preventing and kill off uncultivated area, orchard, farmland weed.
Background technology
The chemical method weeding is one of Main Means of the upper control of agricultural weeds.In recent years, because careless ammonium phosphine large tracts of land is used separately, caused a lot of weeds to develop immunity to drugs.Simultaneously, grass when weeds occur is complicated mutually, not only annual and perennial weed is mixed gives birth to, draft, liana and shrub have concurrently, and weeds emerge uneven, seed, the staggered generation of low age, advanced age weeds, so when the weed killer herbicide kind is used separately, all can show in a certain respect defective and limitation.
Grass ammonium phosphine, chemical formula:
Chemical name: (RS)-2-amino-4-(hydroxymethyl oxygen see base) butyric acid ammonium, English name: glufosinate-ammonium, other Chineses: careless fourth phosphine, phosphine oxamate.The effect characteristics: belonging to the acid herbicides of seeing, is glutamine synthetase inhibitor, has the non-selective contact weedicide of part systemic action.In the short time, disorder is sunk in the ammonium metabolism in the plant corpus after the dispenser, and the cytotoxic agent ammonium ion is accumulated in plant corpus, and meanwhile, photosynthesis is reached the weeding purpose by severe inhibition.
Aryloxyphenoxypropanoates class weed killer herbicide is fluorine-containing, heterocycle, the optical activity weed killer herbicide that a class is prevented and kill off grassy weed, and principal item has:
Diclofop-methyl, chemical name: 2[4 (2', 4'-dichlorophenoxy) phenoxy group] methyl propionate.
Efficient fluazifop, chemical name: (R)-the 2-{4-[(5-trifluoromethyl)-2-base-pyridine radicals] the oxygen base } butyl propionate.
Haloxyfop-r-methyl, chemical name: 2-[4-(5-trifluoromethyl-3-chloro-pyridine-2-oxygen base) phenoxy group] methyl propionate.
Quizalotop-ethyl, chemical name: (R)-and 2-[4-(6-chloroquinoxalin-2-yloxy) phenoxy group] ethyl propionate.
Fenoxaprop, chemical name: (R)-and 2-[4-(6-chloro-1,3-benzoxazole-2-base oxygen) phenoxy group] ethyl propionate.
Evil oxalic acid, chemical name: 2-isopropylidene amino-oxygen ethyl (R)-2-[4-(6-chloroquinoxalin-2-yloxy) phenoxy group] propionic ester.
Cyhalofop-butyl, chemical name: (R)-2-[4 (4-cyano group-2-fluorophenoxy) phenoxy group]-butyl propionate
Clodinafop-propargyl, chemical name: R-2-[4-(5-chloro-3-fluoro-2-oxygen yl pyridines)-phenoxy group]-propiolic acid.
Being mixed of different pesticide species is the common methods of the agriculture disease pest and weed of control.By the formulation of pesticide screening, filter out rational prescription, but the actual control efficiency of Effective Raise reduces dosage, reduces cost, delays the drug-fast generation of disease pest and weed, be the important means that agricultural synthesis is administered.The inventor conducts in-depth research the prescription screening of careless ammonium phosphine and aryloxy group phenoxy propionic acid class weed killer herbicide, find that careless ammonium phosphine and aryloxy group phenoxy propionic acid class weed killer herbicide are mixed and in certain mixed ratio scope weeds are had obvious summation action, after further study, finished the present invention.
Being mixed and using of grass ammonium phosphine and aryloxy group phenoxy propionic acid class weed killer herbicide there is no report at present.
Summary of the invention
Technical problem to be solved: the object of the invention is to solve the deficiency that above-mentioned weed killer herbicide is actual in using, a kind of efficient, low-cost, Herbicidal combinations of being conducive to the weeds comprehensive regulation is provided.
Another object of the present invention provides and this Herbicidal combinations is applied to prevent and kill off the weeds such as uncultivated area, orchard, ridge
Technical scheme: for achieving the above object, the invention provides a kind of Herbicidal combinations take careless ammonium phosphine and aryloxy group phenoxy propionic acid class weed killer herbicide as active ingredient, described aryloxy group phenoxy propionic acid class weed killer herbicide is a kind of of diclofop-methyl, efficient fluazifop, haloxyfop-r-methyl, Quizalotop-ethyl, fenoxaprop, propaquizafop, cyhalofop-butyl, quinoline standing grain sugar ester, clodinafop-propargyl.Grass ammonium phosphine and the ratio of weight and number of aryloxy group phenoxy propionic acid class weed killer herbicide in composition are 50:1～1:1, and careless ammonium phosphine and aryloxy group phenoxy propionic acid class weed killer herbicide weight summation percentage by weight in composition are 10%～80%.
Described Herbicidal combinations is prepared into a kind of of aqueous emulsion, suspending agent, wetting powder, water dispersible granules by pesticide production technology.The production technology of various application forms all belongs to existing known technology, does not repeat them here.
The Herbicidal combinations of careless ammonium phosphine provided by the invention and aryloxy group phenoxy propionic acid class can be applicable to prevent and kill off uncultivated area, orchard, farmland weed.
The Herbicidal combinations of careless ammonium phosphine provided by the invention and aryloxy group phenoxy propionic acid class adopts the method for directed spraying to use usually, also can adopt as required upper other operation techniques used of agricultural.
Herbicidal combinations provided by the invention has following beneficial effect.
1, the Herbicidal combinations of careless ammonium phosphine provided by the invention and aryloxy group phenoxy propionic acid class, in certain ratio range, show obvious summation action, the control efficiency of composition is significantly improved than single dose, reduced the using dosage of agricultural chemicals, reduced the medication number of times, reduce drug cost, reduced the adverse effect of agricultural chemicals to ecotope.
2, the Herbicidal combinations of careless ammonium phosphine provided by the invention and aryloxy group phenoxy propionic acid class, the combination of two kinds of active ingredients, not only can remedy careless ammonium phosphine single dose to the deficiency of the drug-resistant type weeds weak effects such as eleusine indica, Bermuda grass, and the weed killer herbicide that can remedy aryloxy group phenoxy propionic acid class can only be prevented and kill off broad leaved weed, sedge weed and the defective substantially invalid to other weeds classes.
3, the Herbicidal combinations of careless ammonium phosphine provided by the invention and aryloxy group phenoxy propionic acid class, two kinds of active ingredient mechanism of action are different, can overcome the shortcoming that long-term single use easily produces resistance, prolong the service life of medicament, to the comprehensive regulation important in inhibiting of Weed Resistance.
4, the Herbicidal combinations of careless ammonium phosphine provided by the invention and aryloxy group phenoxy propionic acid class, use cost is low, and is easy to use, time saving and energy saving, and it applies huge economic benefit and social benefit.
