Abstract

The present invention belongs to the field of pesticide formulations and relates to a herbicide, especially a paraquat-fluoroglycofen ethyl water-soluble granule and a preparation method thereof. The paraquat-fluoroglycofen ethyl water-soluble granule comprises the following components in weight part: 5-80 parts of paraquat, 0.1-20 parts of fluoroglycofen ethyl, 0.5-15 parts of dispersant, 0.1-10 parts of wetting agent, 0.1-20 parts of disintegrating agent and 1-60 parts of fillings. Compared with the prior art, based on the characteristics of paraquat and fluoroglycofen ethyl, the paraquat and the fluoroglycofen ethyl are perfectly combined together. In this way, the paraquat-fluoroglycofen ethyl water-soluble granule is faster in weeding speed and wider in herbicide controlling spectrum compared with the paraquat aqueous solution. Meanwhile, the paraquat-fluoroglycofen ethyl water-soluble granule is in the form of a granule, so that people cannot easily swallow the paraquat-fluoroglycofen ethyl water-soluble granule. Therefore, the casualties caused by the swallowing of the paraquat-fluoroglycofen ethyl water-soluble granule in a sudden impulse can be reduced.

Description

technical field [0001] The invention belongs to the field of pesticides and medicaments, and relates to herbicides, in particular to a soluble granule of paraquat * acifluorfen and a preparation method thereof. Background technique [0002] Paraquat, whose chemical name is 1-1-dimethyl-4-4-bipyridine cationic salt, is a fast-killing herbicide. The photosynthetic system in the chloroplast of green plants absorbs light energy to produce sugar, thereby providing plants with nutrient. Paraquat has precise access to a biochemical system known as the photosynthetic system, which generates free electrons to drive photosynthesis. Paraquat ions react with these electrons to form "free radicals," which oxygen rapidly converts to peroxides , These peroxides are easy to react with unsaturated fatty acids in the cell membrane. After this series of chemical reactions, the cell membrane is destroyed, and the contents of the cell leak and mix, causing greater damage and causing it to die. ...
