|Section2= |Section3= }} Bromacil is an organic compound with the chemical formula C9H13BrN2O2, commercially available as a herbicide. Bromacil was first registered as a pesticide in the U.S. in 1961.〔United States Environmental Protection Agency. "Bromacil". 1996, p.1-11. Accessed October 9, 2012〕 It is used for brush control and non-cropland areas.〔Cornell University. “Bromacil”. 1993, p. 1. Accessed October 9, 2012〕 It works by interfering with photosynthesis by entering the plant through the root zone and moving throughout the plant.〔USDOE-Bonneville Power Administration. 2000, p.1-9. Accessed October 9, 2012〕 Bromacil is one of a group of compounds called substituted uracils. These materials are broad spectrum herbicides used for nonselective weed and brush control on non-croplands, as well as for selective weed control on a limited number of crops, such as citrus fruit and pineapple.〔 Bromacil is also found to be excellent at controlling perennial grasses. ==Safety== There are quite a few safety precautions that should be taken when dealing with Bromacil. Dry formulations containing bromacil must bear the word "Caution" and liquid formulas must signal "Warning."〔 Care should be exercised when spraying Bromacil on plants because it will also stop the photosynthesis of the adjacent non-target plants, therefore killing them. Bromacil should never be used in residential or recreation areas for risk of exposure. Bromacil is slightly toxic if individuals accidentally eat or touch residues and practically nontoxic if inhaled. Bromacil is a mild eye irritant and a very slight skin irritant. It is not a skin sensitizer.〔Washington State Department of Transportation. “Bromacil”. 2006, p.1-4. Accessed October 9, 2012〕 In studies using laboratory animals, bromacil is slightly toxic by the oral, dermal, and inhalation routes and has been placed in Toxicity Category IV (the lowest of four categories) for these effects.〔 This herbicide should be stored in a cool, dry place and after any handling a thorough hand-washing is advised. In regards to occupational exposure, the National Institute for Occupational Safety and Health has recommended workers handing bromacil not exceed an exposure of 1 ppm (10 mg/m3) over an eight-hour time-weighted average. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bromacil」の詳細全文を読む スポンサード リンク
