Abstract
The present invention relates to kind of biocidal herbicide and its production process. The biocidal herbicide consists of glyphosate isopropylamine salt, glyphosate amine salt and 2, 4-D salt. The production process includes mixing glyphosate powder, isopropylamine and water to obtain clear solution; and adding glyphosate amine salt, 2, 4-D salt and surfactant through mixing homogeneously to obtain the biocidal herbicide. The biocidal herbicide has fast and complete herbicidal effect.
Description
(1) technical field
The present invention relates to a kind of steriland herbicide and production method thereof.
(2) background technology
Glyphosate salt is widely used as the broad-spectrum herbicide of noresidue or low-residual.Though glyphosate itself is very effective phytotoxicity agent or weed killer herbicide, yet because its organic solvent water insoluble and commonly used can not satisfy the commercialization requirement, its derivative too.Therefore, have at least a substituted glyphosate derivative of hydrogen to become water soluble salt in the more diffluent hydroxyl of use usually with form.Present most widely used salt is the isopropyl amine salt of glyphosate.
Based on the unsettled defective of high concentration glyphosate salt, International Patent Application WO 8403607 discloses the composition of a kind of glyphosate isopropyl amine salt and glyphosate ammonia salt.Chinese patent application CN1504094A provides a kind of preparation method of the glyphosate isopropyl amine salt aqueous solution safe, economic, simple to operate.Above-mentioned two patents have solved the preparation and the stability in use problem of glyphosate salt, and do not relate to the growth of concrete herbicidal effect.
(3) summary of the invention
The object of the present invention is to provide a kind of steriland herbicide and production method thereof, can significantly improve the quick-acting and the completeness of weeding.
Steriland herbicide of the present invention comprises glyphosate isopropyl amine salt, ammonium glyphosate and 2,4-D salt.
Described glyphosate isopropyl amine salt is Chinese common name, and chemical name is: N-phosphine carboxymerhyl-glycine isopropyl amine salt, molecular formula is: C

5P, structural formula is:
When the composition of described weed killer herbicide is applied as aqua, aqua form can for:
Glyphosate isopropyl amine salt 1～40%;
Ammonium glyphosate 1～40%;
2,4-D salt 0.1～10%;
Surplus is a water; Described percentage is percetage by weight.
Different amine salt of glyphosate and ammonium glyphosate weight content sum are preferably 15～50% in the described weed killer herbicide aqua, and 2,4-D salt weight content is preferred 0.1～6%.Described 2,4-D salt consumption more preferably the different amine salt of glyphosate and ammonium glyphosate weight summation 0.15～10%, most preferably be 0.3～7%.
Above-mentioned 2,4-D salt is a kind of hormone herbicide, as 2, and 4-D dimethylamine salt etc., it stimulates meristematic tissue abnormal division after absorbing by weeds, quickens respiration, nutrient consumption is accelerated, at last because of unable to make ends meet and dead.Weed killer herbicide of the present invention can effectively improve glyphosate to because low temperature and or the low humidity condition under poky plant or for the effect of the plant that is in latter stage in plant growing cycle, significantly improve the quick-acting and the completeness of glyphosate salt.
Described steriland herbicide can and preferably contain the auxiliary agent of weight content 1～20%, described auxiliary agent is the conventional surfactant that is used for agricultural chemicals, as one of following or several mixture arbitrarily: alkyl glycoside, tallow amine ethyl group thing, Tea Saponin, cocoa butter amide betaine, cocoa butter betain, organosilicon ethers, sebum are preferably alkyl glycoside.
Described steriland herbicide can method routinely mix preparation promptly with each component, as preparing as follows:
Will be by weight ratio load weighted glyphosate ammonium salt raw powder (or ammonium glyphosate preparation) mix with load weighted glyphosate isopropyl amine salt by weight ratio, add the water stirring and dissolving, and then add it with by weight ratio load weighted 2,4-D salt and/or auxiliary agent stir, and obtain finished product after the filtration.
Ammonium glyphosate in the described weed killer herbicide can adopt glyphosate ammonium salt raw powder or various ammonium glyphosate preparation (as aqua), and glyphosate isopropyl amine salt can adopt various glyphosate isopropyl amine salt preparations (as aqua).
Described steriland herbicide also can get by following prepared in reaction:
The former powder of glyphosate, water, isopropylamine are mixed stirring until the solution clarification, add ammonium glyphosate, 2 again, 4-D salt and/or auxiliary agent mix and promptly get described steriland herbicide.
Steriland herbicide of the present invention has improved the quick-acting and the completeness of glyphosate herbicidal effectively.
