EXTOXNET PIP -PARAQUAT Page 1 of 4 <br /> EXTOXNET <br /> Extension Toxicology Network <br /> Pesticide Information Profiles <br /> A Pesticide Information Project of Cooperative Extension Offices of Cornell University, Oregon State University, the <br /> University of Idaho, and the University of California at Davis and the Institute for Environmental Toxicology,Michigan <br /> State University. Major support and funding was provided by the USDA/Extension Service/National Agricultural <br /> Pesticide Impact Assessment Program. <br /> EXTOXNET primary files maintained and archived at Oregon State University <br /> Revised June 1996 <br /> Paraquat <br /> Trade and Other Names: Product names include Crisquat, Cyclone, Dextrone, Dexuron, Gramoxone Extra, <br /> Herbaxone, Ortho Weed and Spot Killer, and Sweep. The compound may be found in formulations with many other <br /> herbicides,including simazine and diquat dibromide. <br /> Regulatory Status: Paraquat is a highly toxic compound in EPA toxicity class I. Products containing it must be is <br /> labeled with the Signal Words DANGER -POISON. Paraquat is a Restricted Use Pesticide(RUP). RUPs may be <br /> purchased and used only by certified applicators. <br /> Chemical Class: quaternary nitrogen compound <br /> Introduction:Paraquat is a quaternary nitrogen herbicide widely used for broadleaf weed control. It is a quick-acting, <br /> nonselective compound,that destroys green plant tissue on contact and by translocation within the plant. It has been <br /> employed for killing marijuana in the U.S. and in Mexico. It is also used as a crop desiccant and defoliant, and as an <br /> aquatic herbicide. <br /> Formulation:Not Available <br /> Toxicological Effects: <br /> . Acute toxicity: Paraquat is highly toxic via ingestion, with reported oral LD50 values of 110 to 150 mg/kg in rats, <br /> 50 mg/kg in monkeys, 48 mg/kg in cats, and 50 to 70 mg/kg in cows [8,87]. The toxic effects of paraquat are due to <br /> the cation, and the halogen anions have little toxic effects [87]. The dermal LD50 in rabbits is 236 to 325 mg/kg, <br /> indicating moderate toxicity by this route [58,87]. The 4-hour inhalation LC50 is greater than 20 mg/L for the <br /> technical grade of the compound [87]. It causes skin and eye irritation in rabbits (severe for some of the formulated <br /> products) and also has caused skin sensitization in guinea pigs in some formulations [87]. Effects due to high acute <br /> exposure to paraquat may include excitability and lung congestion, which in some cases leads to convulsions, <br /> incoordination, and death by respiratory failure [87]. If swallowed, burning of the mouth and throat often occurs, <br /> http://extoxnet.orst.edu/pips/paraquat.htm 3/26/2007 <br />
