Abstract
The invention provides a drop acid and glyphosate soluble additive, which is used for improving quick acting property, broad spectrum property and the like of drop acid and glyphosate soluble agent, increasing the solubility of 2,4-D and increasing the utilization rate of glyphosate and 2, 4-D. The specific formula comprises 5% -12% of octanoyl amide propyl dimethylamine, 17% -27% of decanoyl amide propyl dimethylamine, 20% -25% of lauroyl amide propyl dimethylamine, 1% -3% of tetradecyl amide propyl dimethylamine, 3% -5% of palmitoyl amide propyl dimethylamine, 2% -4% of stearoyl amide propyl dimethylamine and 29% -39% of soft water. The additive is used for producing the solution of the citric acid and the glyphosate, and the additive amount is 8 percent. The compound herbicide can completely dissolve 2,4-D salt and is compounded with ammonium glyphosate, the compound herbicide has good weeding effect and quick-acting property, and the low-temperature stability and lasting foamability of the compound herbicide are further improved.
Description
Technical Field
The invention discloses a di-acid-glyphosate soluble auxiliary agent, belongs to the field of herbicides, and particularly has a good synergistic effect on a di-acid-glyphosate compound preparation.
Background
Glyphosate is a biocidal organophosphorus herbicide developed by Monsanto in seventies of the twentieth century, which has an inhibitory effect on 5-enolpyruvyl-shikimate-3-phosphate synthase (EPSP synthase), thus inhibiting the synthesis of aromatic amino acids and eventually causing plant death. 2,4-D is a phenoxy carboxylic acid herbicide, which is absorbed into plants through roots, stems and leaves, is slowly metabolized, can accumulate a certain concentration, thus interfering with the balance of active hormone in the plants, and destroying the metabolism of protein and nucleic acid, and can inhibit or promote the growth of certain organs of the plants, thereby leading to thickening of weed stems, distortion of stems and leaves, swelling and cracking.
The glyphosate is colorless crystal, with melting point of 200deg.C, solubility in water of 12g/L (25deg.C), and is insoluble in common organic solvent, but is easily dissolved in water after being made into sodium salt or ammonium salt, and the preparation is processed into sodium salt, isopropylamine salt or dimethylamine salt.
The 2,4-D pure product is white to yellow crystalline powder, the melting point is 137 ℃, the 2,4-D pure product is slightly soluble in water, and the sodium salt is prepared and then is dissolved in alkali solution and alcohols. The 2,4-D and the glyphosate are mixed and prepared, so that the quick-acting property can be exerted and the synergy can be achieved. During the production of the preparation, some surfactants are often added to promote the absorption of the preparation by plant leaves, and the surfactants influence the efficacy of the preparation by changing the surface tension, contact angle, wetting force and the like of the liquid medicine.
Lauramidopropyl dimethylamine, otherwise known as lauramidopropyl-dimethyl tertiary amine; dodecyl acyl propyl dimethyl tertiary amine; n- [3- (dimethylamino) propyl ] lauramide, etc., abbreviated as PKO-12. It can be used as an important intermediate for producing amine oxide, betaine and quaternary ammonium salt, and can be used as emollient, emulsifier, conditioner and softener for producing skin care products, hair conditioner, lubricating cutting oil, asphalt emulsifier, papermaking textile auxiliary agent, petroleum product additive, etc.
Tetradecylamide propyldimethylamine, also known as myristylamide propyldimethylamine. It is an amidoamine compound, a surfactant, and is commonly used in cosmetics as an emulsifier, a stabilizer, a preservative, etc.
Palmitoamidopropyl dimethylamine, a nonionic surfactant, is insoluble in water and is relatively stable. Has excellent emulsifying, dispersing, corrosion inhibiting, lubricating, antistatic and solubilizing properties. Can be used as an emulsifier, a dispersant, a lubricant, a corrosion inhibitor and an antistatic agent and also can be used as an organic synthesis intermediate.
The stearamidopropyl dimethylamine alias stearamidopropyl dimethyl tertiary amine is a cationic surfactant and has high biodegradability and low toxicity. Can be used for emulsifying agent, wetting agent, dispersing agent, antistatic agent, softening agent, detergent, antirust agent, thickening agent, bactericide, etc.
According to their own characteristics, octanoyl amide propyl dimethylamine, decanoyl amide propyl dimethylamine, lauroyl amide propyl dimethylamine, tetradecyl amide propyl dimethylamine, palmitoyl amide propyl dimethylamine and stearoyl amide propyl dimethylamine are all good pesticide synergists, and are mixed according to a certain proportion, so that the cost is saved and the synergism is maintained. The auxiliary agent of the solution of the citric acid and the glyphosate is added into the solution of the citric acid and the glyphosate according to a certain proportion, the compound herbicide has good weeding effect and quick action, and the low-temperature stability and the lasting foamability of the compound herbicide are further improved.
Disclosure of Invention
The invention aims to provide a drop acid-glyphosate soluble auxiliary agent which has the advantages of broad weed control spectrum, quick response, long lasting period and no rebound. The octanoyl amide propyl dimethylamine, the decanoyl amide propyl dimethylamine, the lauroyl amide propyl dimethylamine, the tetradecyl amide propyl dimethylamine, the palmitoyl amide propyl dimethylamine and the stearoyl amide propyl dimethylamine are taken as raw materials, can be uniformly mixed at normal temperature, and then a proper amount of soft water is added to make up the balance. The emphasis of the process is on the sequence of proportioning and mixing of the components.
