Abstract
The invention discloses a method for using amino acid polymer to improve the weeding effect of glyphosate and a preparation method of complex dispersible granules, soluble powder and aqueous solution agent. Compared with the method by only using glyphosate, the complex can be used to greatly increase the weeding activity of glyphosate, reduce the dosage of glyphosate and increase the operation efficiency.
Description
Technical field
The present invention relates to a kind of Herbicidal synergistic compound, particularly contain the Synergistic complex 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.Poly-aspartic-acid is the efficient synergist of a kind of fertilizer and novel plant nutrient absorption promoter and conditioning agent.Plant desired nutritional composition had extremely strong chelating function, have advantages such as long-chain albumen and anion surfactant, promote the absorption of plant, promote the transportation of glyphosate in plant corpus nutritive element, and accelerate plant corpus metabolism, quicken the consumption of nutrient in the plant corpus.Thereby help the lifting of the removing activity of glyphosate.
Also there be not at present the relevant report of poly-aspartic-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.Poly-aspartic-acid has advantages such as long-chain albumen and anion surfactant, can promote the absorption of plant to nutritive element, promotes the transportation of glyphosate in plant corpus, and accelerates plant corpus metabolism, quickens the consumption of nutrient in the plant corpus.
By a large amount of biologicall test experiments, the researcher finds that this glyphosate and poly-aspartic-acid combination can obviously promote glyphosate and kill careless speed and effect.
The researcher also makes the composition of glyphosate and poly-aspartic-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 poly-aspartic-acid was made water dispersible granules, wherein each composition weight proportioning was: glyphosate 1%--80%, poly-aspartic-acid 1%--30%, 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 poly-aspartic-acid was made soluble powder, wherein each composition weight proportioning was: glyphosate 1%--80%, poly-aspartic-acid 1%--30%, 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 poly-aspartic-acid was made aqua, wherein each composition weight proportioning was: glyphosate 1%--80%, poly-aspartic-acid 1%--30%, surfactant 5%--15%.Surfactant is one or more in benzylphenol APEO, alkylphenol polyoxyethylene, the aliphatic alcohol polyethenoxy.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.
