Example

[0025] Examples 1 to 5

[0026] According to the components and measurement data shown in Table 1, glyphosate isopropylamine salt and glyphosate ammonium salt original powder are mixed, add water and stir to dissolve, then add 2,4-D salt and additives and stir evenly, after filtering A finished herbicide is obtained.

Example

[0028] Examples 6 to 11

[0029] According to the components shown in Table 2 and their measurement data, the original glyphosate powder and water were added to the reaction vessel, and isopropylamine was added while stirring until the solution was clarified, and then the original powder of ammonium salt of glyphosate was added to the reaction vessel. Stir evenly; finally add 2,4-D salt and auxiliary and mix evenly to obtain the finished herbicide.

[0031] Example 12 Drug effect test

[0032] The biocidal herbicides obtained in Examples 1 to 11 were selected respectively, and the test was carried out in the leisure area of ​​Genglou, and the weed species were mainly sedge, bermudagrass and the like. The Hongxing brand hand pressure sprayer was used, the plots were randomly arranged, each plot was 5 square meters, 2 repetitions, 6 treatments, the dosage per mu in this experiment was 147ml, and the amount of water added was 30kg per mu, uniformly sprayed. On November 2, 2004, the medication was taken. The weather was sunny and the temperature was around 15-20℃. It rained heavily on the sixth day after the medication, and the temperature was around 8-18℃. The CD method was used to record the test results, and the obtained efficacy data were shown in Table 3 and Table 4. Table 3 shows the efficacy data when the 2,4-D salt content is less than or equal to 3%, and Table 4 shows the drug efficacy data when the 2,4-D salt conten...

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 [0001] The present invention relates to a total herbicide and its production method. (2) Background technology [0002] Glyphosate salts are widely used as no-residue or low-residue broad-spectrum herbicides. Although glyphosate itself is a very effective phytotoxic agent or herbicide, it cannot meet commercial requirements because it is insoluble in water and common organic solvents, and neither are its derivatives. Therefore, glyphosate derivatives in which at least one hydrogen in the more soluble hydroxyl group has been substituted are generally used to form water-soluble salts. The most widely used salt is the isopropylamine salt of glyphosate. [0003] Based on the instability of high-concentration glyphosate salt, international patent application WO8403607 discloses a composition of glyphosate isopropylamine salt and glyphosate ammonium salt. Chinese patent application CN1504094A provides a safe, economical and easy-to-operate preparation method...
