Abstract
The invention relates to a weeding composition containing glufosinate-ammonium and amides. The weeding composition is mainly characterized by containing 1-80% of effective component A glufosinate-ammonium and 1-80% of effective component B, wherein the effective component B is selected from any one of the following herbicides: propisochlor, acetochlor and pretilachlor. The weeding composition is prepared into wettable powder, water-dispersible granules, oil suspending agent, microemulsion, aqueous emulsion or microcapsule suspending agent. The weeding composition provided by the invention is used for controlling weed.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Herbicidal combinations that contains careless ammonium phosphine and amide-type, be used for controlling weeds.
Background technology
The direction of pesticide developing was to embody efficient, low toxicity, low-residual and pollution-free in recent years.Be embodied in pursuit " three height ", namely (1) is safe, and this not only requires toxicity low, and is residual low, and nuisanceless; (2) biologically active is high; (3) selectivity is high.Therefore continue to improve the performance of present Pesticidal products, reach efficient, low toxicity, free of contamination requirement.So, select the agricultural chemicals of composite mixture just to become current first-selection and a kind of effective approach, be that the agricultural chemicals of performance complement obtains best synergistic effect by the proportioning of adjusting different agricultural chemicals.
Grass ammonium phosphine (Glufosinate-ammonium) chemical name: (RS)-2-amino-4-(hydroxymethyl oxygen see base) butyric acid ammonium, molecular formula: C
5H
13N
2O
4P.Grass ammonium phosphine belongs to the acid herbicides of seeing, and 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.
Propisochlor, Acetochlor, the third careless amine all belong to acetamide-group herbicides, acetamide-group herbicides are selectivity preemergence herbicides, the plant sprout of mainly being germinateed absorbs, monocotyledon absorbs by bud scale, dicotyledon hypocotyl Assimilation and conductivity, but Profilin matter is synthetic, and photosynthetic and respiration are had remote-effects.Early stage soil spraying is processed before the bud or behind the bud, the weeds seedling that is injured distortion, and the primary leaf difficulty is stretched out, and the leaf look deepens green, and growth stops, until dead.
The chemical composition of each weed killer herbicide, formation and physic-chemical property all are distinguishing.Therefore, their herbicide ability and scope are also different.Some weed killer herbicide herbicide spectrum is narrower, but has one's own knack, and can eradicate the weeds that are difficult to eliminate with other weed killer herbicide.Along with further developing of weed killer herbicide production and application, using with gradually between the weed killer herbicide grows up.China also comparatively payes attention to using with aspect the research of weed killer herbicide, extensively is recognized as one of important measures that weed killer herbicide rationally uses, and has worked out a series of Herbicidal compositions, has obtained greater advance.
My company also is devoted to the research and development of Herbicidal compositions.At present, have no report about careless ammonium phosphine with the relevant composite product of propisochlor, Acetochlor, the third careless amine.
Summary of the invention
The Herbicidal combinations that the purpose of this invention is to provide careless ammonium phosphine of containing of a kind of controlling weeds.
A kind of Herbicidal combinations that contains careless ammonium phosphine and amide-type, Herbicidal combinations contain effective constituents A grass ammonium phosphine 1% ~ 80%, and active ingredient B1% ~ 80%, active ingredient B are selected from a kind of in propisochlor, Acetochlor, the third careless amine.Herbicidal combinations preferably contains careless ammonium phosphine 1% ~ 60%, and active ingredient B 1% ~ 60%; Herbicidal combinations more preferably contains careless ammonium phosphine 2% ~ 30%, propisochlor 4% ~ 50%; Herbicidal combinations more preferably contains careless ammonium phosphine 2% ~ 30%, Acetochlor 3% ~ 50%; Herbicidal combinations more preferably contains careless ammonium phosphine the 2% ~ 30%, third careless amine 3% ~ 50%.
Herbicidal combinations of the present invention is used for the weeds of control uncultivated area, orchard, tea place, no-tillage field, sugarcane field, Cotton Fields, Spring Maize, sisal hemp garden, wooden land, mulberry field, forest.
Multiple weeds are such as grassy weed, broad leaved weed, sedge weed, annual weed, perennial weed etc.
Described Herbicidal combinations, composition is made any formulation of agricultural chemicals, be preferably wetting powder, water dispersible granules, oil-suspending agent, microemulsion, aqueous emulsion, microcapsule suspending agent, also can be made into microcapsule suspension-suspending agent, soluble liquid, soluble powder.
When making wetting powder, composition comprises following constituent content: effective constituents A 1% ~ 80%, active ingredient B 1% ~ 80%, dispersant 1% ~ 12%, wetting agent 1% ~ 8%, filler surplus.
