Major support and funding was provided by the <br />USDA/Extension Service/National Agricultural Pesticide Impact Assessment Program. <br />EXTOXNET primary files maintained and archived at Oregon State University <br />Revised June 1996 <br />Bromacil <br />Trade and Other Names: Trade names include Borea, Bromax 4G, Bromax 4L, Borocil, Cynogan, <br />Hyvar X, Hyvar XL, Isocil, I{rovaz, Rout, Uragan, Urox B, and Urox HX. <br />Regulatory Status: Bromacil is classified by the U. S. Environmental Protection Agency (EPA) as a <br />General Use Pesticide (GUP). It is in toxicity class IV -practically nontoxic in dry form, and class II - <br />moderately toxic in the liquid form. Dry formulations containing bromacil bear the Signal Word <br />CAUTION. Because of their irritating effects on skin, eyes, and the respiratory tract, liquid formulations <br />bear the Signal Word WARNING. <br />Chemical Class: Not Available <br />Introduction: Bromacil is an herbicide used for brush control on non-cropland areas. It is especially <br />useful against perennial grasses. It is also used for selective weed control in pineapple and citrus crops. It <br />works by interfering with photosynthesis, the process by which plants use sunlight to produce energy. <br />Bromacil is one of a group of compounds called uracils. It is sprayed or spread dry on the soil surface just <br />before, or during, a period of active weed growth. It is available in granulaz, liquid, water soluble liquid, <br />and wettable powder formulations. <br />Formulation: It is available in granular, liquid, water soluble liquid, and wettable powder formulations. <br />Toxicological Effects: <br />• Acute toxicity: Liquid formulations of bromacil are moderately toxic, while dry formulations are <br />practically non-toxic [8]. The herbicide is irritating to the skin, eyes, and respiratory tract [68]. <br />When 100 mg/kg of the herbicide was fed to dogs, it caused vomiting, watering of the mouth, <br />muscular weakness, excitability, diarrhea, and dilation of the pupils. Rats [hat were fed single doses <br />1 0(4 I I/IS/98 10:40 AM <br />
