Chloroxuron
Chloroxuron is a phenylurea herbicide that appears as an odorless and colorless powder or white crystals. Phenylurea pesticides are characterized for their agricultural use to control weed growth, acting as photosynthesis inhibitors. These herbicides can either be endocrine disruptors, or have ecotoxic or genotoxic effects. Chloroxuron's herbicide resistance class is Group C, (Australia), C2 (global), Group 7, (numeric); it is a urea and photosynthesis inhibitor. Chloroxuron was initially produced by Ciba-Geigy in the 1960s as a herbicide. Chloroxuron can be found as a colorless powder or as a white crystal. Chloroxuron in particular is used for the control of annual grasses, mosses and broad-leaved weeds, and is useful for common crop plants such as soy beans, onions, strawberries, and celery. The herbicidal effects of chloroxuron act by inhibiting photosynthesis. Inhibition of photosynthesis promptly blocks the plant’s ability to produce ATP and leads to death. Chloroxuron inhibits photosynthesis by blocking the electron transport chain in the photosystem II. Chloroxuron is classified as an extremely hazardous substance in the United States as defined in Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act (42 U.S.C. 11002), and is subject to strict reporting requirements by facilities which produce, store, or use it in significant quantities.…
