Abstract

The invention relates to a water dispersible granule of a herbicide. The water dispersible granule has the beneficial effects the active ingredients including amidosulfuron and pyraflufen-ethyl in the herbicide do not collide with each other when being mixed with each other; the herbicide has a wide weed control spectrum; through cooperation of the active ingredients in the herbicide, the herbicide has good synergistic effects in a certain range, has better control effects than a single agent and has long property duration; the herbicide is safe to crops.

Description

technical field [0001] The invention relates to a herbicide, in particular to a herbicide water dispersible granule. Background technique [0002] sulfuron-methyl Belonging to sulfonylureas, the pure product is white granular solid; melting point 160~163°C; density 1.5 (20°C); vapor pressure 2.2×10-5Pa (20°C). Partition coefficient LogP (20°C) = 1.63 (pH 2); solubility (20°C, mg / l) is: 3.3 (pH 3), 9 (pH 5.8), 13500 (pH 10) in water, isopropanol 99, methanol 872, acetone 8100; stable at room temperature for 24 months; p K a 3.58. Acetylsulfuron-methyl is an inhibitor of acetolactate synthase (ALS). Absorbed by the roots and leaves of the weeds, and conducted in the plant, the weeds stop growing, the leaves turn green, and then die. It can be prepared by using methylsulfonamide and dimethoxypyrimidinamine as starting materials. [0003] metazachlor It is pyrazoles, the pure product is a brown solid; the melting point is 126~127°C; the vapor pressure is 4.79×10-3Pa (25°...
