Diuron is a systemic and conductive broad-spectrum herbicide, which can be absorbed by the roots and leaves of plants, mainly absorbed by the roots. After the weed root system absorbs the chemical, it spreads to the leaves on the ground, and spreads around along the leaf veins. Inhibits the Hill reaction in photosynthesis, which requires light to kill plants. The affected weeds start to fade from the tip and edge of the leaves, and eventually the whole leaves wither, unable to produce nutrients, and starve to death. Diuron is effective against most annual and perennial weeds for more than 60 days. Mainly used in sugarcane fields to control crabgrass, foxtail grass, wild wheat grass, tendon grass, teff, barnyardgrass, quinoa, Polygonum vulgaris, anti-branch amaranth, mother-in-law Lana, solitary vegetables, small fly cockroaches, Kanmainiang, shepherd's purse , Artemisia annua, chickweed, Cyperus officinalis, bermudagrass, paspalum, spinach, reed, Imperata, etc. In high doses, it can be used as a biocidal herbicide.
