Abstract
The invention discloses an effectiveness-enhanced glyphosate weeding combination and a preparation method for dispersible granule, water soluble powder and aqueous solution agent thereof. Compared with the glyphosate which is independently used, the invention has the advantages that the combination can greatly promote the weeding activity of the glyphosate, the use amount of the glyphosate is reduced and the use efficiency is improved.
Description
Technical field
The present invention relates to a kind of Synergistic herbicide compositions, particularly contain the synergistic composition of glyphosate.
Background technology
Glyphosate (glyphosate), formal name used at school N-((phosphonomethyl)) glycine, N-((phosphonomethyl)) amion acetic acid (Phosphonomethyl Imino Acetic Acid) is a kind of organophosphorus herbicide by the exploitation of U.S. Monsanto Company.Glyphosate absorbs by plant leaf blade and non-woody cauline leaf as non-selective, noresidue herbicide after seedling, conducts to the plant corpus each several part.Very effective to dark root perennial weed and annual and biennial grass family, sedge family and broad leaved weed.The most outstanding characteristics of glyphosate are in can being conducted to underground rhizome downwards and be tillered by the cauline leaf absorption, and are extremely strong to weeds underground organization destructive power.It kills grassland reason mainly is by suppressing the activity of enol acetonyl shikimene phosphate synthase, destroy the conversion of shikimene to phenyl alanine, tyrosine, tryptophan, thereby protein synthesis is interfered and causes plant death.P-chlorophenoxyacetic acid is a plant growth regulators, inhale conduction in having, can promote or suppress plant growing, can prevent the fruit drop of melon and fruit class and other crops effectively, and have the precocity of promotion, sub real the expanding of promotion, improve multiple functions such as sub real quality.Also there be not at present the relevant report of p-chlorophenoxyacetic acid to the synergistic effect of glyphosate.
Summary of the invention
But the object of the present invention is to provide a kind of preparation method who has the glyphosate composition of notable synergistic effect and introduce its dispersible granule, soluble powder and aqua.By a large amount of biologicall test experiments, the researcher finds that this glyphosate and p-chlorophenoxyacetic acid combination can obviously promote glyphosate and kill careless speed and effect.
The researcher also makes the composition of glyphosate and p-chlorophenoxyacetic acid water dispersible granules, soluble powder and three kinds of formulations of aqua, and has carried out the comparative efficacy test with the agent of glyphosate list.
When the composition of glyphosate and p-chlorophenoxyacetic acid is made water dispersible granules, wherein each composition weight proportioning is: glyphosate 1%--80%, p-chlorophenoxyacetic acid 0.1%--20%, surfactant 5%--10%, disintegrant 1%--5%, carrier 10%--80%.Surfactant is one or more in lignosulfonates, lauryl sodium sulfate, fatty acid sulphate, aliphatic alcohol polyethenoxy, nekal, the dodecyl polyoxyethylene ether phosphate.Disintegrant is one or more in bentonite, ammonium sulfate, urea, the magnesium sulfate.Carrier is a kind of in algae soil, kaolin, white carbon, the nacrite.
When the composition of glyphosate and p-chlorophenoxyacetic acid was made soluble powder, wherein each composition weight proportioning was: glyphosate 1%--80%, p-chlorophenoxyacetic acid 0.1%--20%, surfactant 5%--15%, carrier 10%--80%.Surfactant is lignosulfonates, lauryl sodium sulfate, fatty acid sulphate, aliphatic alcohol polyethenoxy, nekal, benzylphenol APEO, alkylphenol polyoxyethylene, draw back in the powder one or more.Carrier is a kind of in ammonium sulfate, potassium sulphate, the ammonium chloride.
When the composition of glyphosate and p-chlorophenoxyacetic acid was made aqua, wherein each composition weight proportioning was: glyphosate 1%--80%, p-chlorophenoxyacetic acid 0.1%--20%, surfactant 5%--15%, solvent 5%--15%.Surfactant is one or more in benzylphenol APEO, alkylphenol polyoxyethylene, the aliphatic alcohol polyethenoxy, and solvent is one or more in ethanol, methyl alcohol, isopropyl alcohol, the ethyl acetate.
Compare with the agent of glyphosate list, the present invention has following advantage:
1. herbicide effect is more rapid, and the glyphosate drug effect was brought into play than the fast 48--72 of single glyphosate formulation hour.
2. reduce glyphosate unit are consumption 20%--40%, help economizing on resources and protecting environment.
3. be applied to genetically modified crops, can obviously promote plant growth.
