Embodiment 1～5

[0026] According to the components and their metering data shown in Table 1, mix glyphosate isopropylamine salt with glyphosate ammonium salt powder, add water and stir to dissolve, then add 2,4-D salt and additives and stir evenly, after filtering Obtain the finished herbicide.

[0027] Example

Embodiment 6～11

[0029] According to the components and metering data shown in Table 2, the former powder of glyphosate and water are added in the reaction vessel, and isopropylamine is added while stirring until the solution is clear, then the former powder of glyphosate ammonium salt is added to the reaction vessel and Stir evenly; finally add 2,4-D salt and additives and mix evenly to obtain the finished herbicide.

[0030] Example

Embodiment 12

[0031] Embodiment 12 drug efficacy experiment

[0032] The killing herbicides obtained in Examples 1 to 11 were selected respectively, and the test was carried out in the leisure land of Genglou, and the weed species were mainly sedge, bermudagrass and the like. Red Star brand hand press 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 test was 147ml, the amount of water added was 30kg per mu, and the spray was uniform. On November 2, 2004, the medicine was taken. The weather was fine and the temperature was about 15-20°C during the medicine. After the medicine, it rained heavily on the 6th day, and the temperature was about 8-18°C. Utilize the CD method to record the test results, and the drug efficacy data obtained are shown in Table 3 and Table 4. Table 3 shows the drug efficacy data when the 2,4-D salt content is ≤3%, and Table 4 shows the drug efficacy data when the 2,4-D sa...

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...
