Abstract

The invention discloses a broad-spectrum herbicide and a preparation method thereof. The broad-spectrum herbicide comprises the following raw materials in parts by weight: 30-35 parts of propisochlor, 27-50 parts of urea, 18-20 parts of boric acid, 20-30 parts of o-nitrobenzaldehyde, 20-30 parts of phenylacetic acid, 30-40 parts of amine oxide, 10-40 parts of polyacrylamide, 12-18 parts of disodium phosphate, 10-20 parts of sodium thiosulfate, 20-30 parts of maleic anhydride, 40-50 parts of ethyl acetate, 20-40 parts of methyl isopropyl ketone, 10-20 parts of borax, 6-20 parts of a catalyst and 50-80 parts of water. The preparation method comprises the following steps: weighing raw materials, uniformly mixing, heating for reaction, and cooling to a room temperature. The broad-spectrum herbicide has the activity of eleusine indica, is capable of inhibiting growth, also has a good activity of eclipta prostrate, nightshade, amaranthus and chenopodium serotinum, and is capable of seriously inhibiting the growth of the eclipta prostrate, the nightshade, the amaranthus and the chenopodium serotinum.
