Example Embodiment
[0060] Example 1
[0061] The preparation process is roughly divided into two processes, such as the wet part process and the thickening part process, and is carried out at room temperature.
[0062] By adding water to dipotassium hydrogen phosphate (K 2 HPO 4 ) And potassium dihydrogen phosphate (KH 2 PO 4 In ), a 1L solution was used to prepare a 0.1M phosphate buffer (pH 6.15). After that, 3.0 parts by weight of CR-DOS70P (bis(2-ethylhexyl) sulfosuccinate sodium salt, Cas No. 577-11-7), 1.0 parts by weight of NK-SU500 (sucrose laurate, Cas No. 25339-99-5) and 0.2 parts by weight of SAG-622 (Momentive) as defoamers were added to 65.8 parts by weight of buffer and mixed thoroughly. In a homogenized state, 10.0 parts by weight of methoxyacetic acid 1-(3-{[(4,6-dimethoxy-pyrimidin-2-yl)carbamoyl]sulfamoyl}-2- Pyridyl)-2-fluoropropyl (flupisulfuron, FTS) was added to the mixture, and then mixed thoroughly using a stirrer. Here, the mixture is ground using glass beads until the ave...
Example Embodiment
[0065] Example 2
[0066] A herbicidal composition in the form of a suspension concentrate formulation was prepared in the same manner as in Example 1, except that the pH of the wet part buffer and the thickening part buffer was changed to 5.8.
Example Embodiment
[0067] Example 3
[0068] A herbicidal composition in the form of a suspension concentrate formulation was prepared in the same manner as in Example 1, except that 2 parts by weight of propylene glycol was added to the thickening part and 17.7 parts by weight of phosphate buffer was added.
