..! _ 14 April 2004 AGE-NC Project No.04-1143 Page 9 of 17 Diuron is moderately toxic to animals; for humans,the only reported case of acute,oral exposure to the herbicide produced no significant symptoms or toxicity. It is not considered to be mutagenic or carcinogenic at low doses; it is teratogenic at high doses. Diuron is moderately to highly persistent in soils. Residue half-lives are from 1 month to 1 year. Some pineapple fields contained residues 3 years after the last application. Mobility in the soil is related to organic matter and to the type of the residue. The metabolites are less mobile than the parent compound. In California, diuron has been found in groundwater in the 2 to 3 ppb range. Diuron is relatively stable in neutral water; microbes are the primary agents in the degradation of diuron in aquatic environments. CMR Herbicide Activator: Application (2.50 gallons, 8 ounces per acre) - A 100% active crop oil concentrate used as a spreader/ activator/ penetrator to increase the foliar absorption of various herbicides.It is a blend of 80%petroleum oil and 20%non-ionic surfactant. It has superior blending compatibility with various herbicide formulations.There is no known toxicity to fish,invertebrates, plants or birds. CMR NO FOAMA: Application(80 ounces, 8 oz pints per 100 gallons)A nonionic surfactant used to give optimum wetting and spreading of agricultural insecticides,miticides,fungicides,herbicides and growth regulating hormones.No Foam A is formulated from materials which do not tend to burn foliage or leave harmful residues. There is no known toxicity to invertebrates,plants or birds; some toxicity is noted to some fish. — May 2001 PUR: SURpHTAC ad iuvant Application (3.3 gallons, 50 oz pints per 100 gallons) CMR Herbicide Activator: Application (10 gallons, 2 oz pints per acre) _. POAST(sethoxydim):A General Use Pesticide(GUP).Application(10 gallons,2.00 pints per acre) The U.S. EPA classifies it as toxicity class III - slightly toxic- Sethoxydim is a selective post- emergence herbicide used to control annual and perennial grass weeds in broad-leaved vegetable, fruit, field, and ornamental crops. It also has indoor uses. It is available in emulsifiable concentrate formulations. Diuron is not considered to be mutagenic, carcinogenic or teratogenic at expected doses. Sethoxydim is of low soil persistence. Reported field half-lives are 5 to 25 days. It has a weak tendency to adsorb to soil particles [58]. Laboratory leaching tests have suggested that sethoxydim could leach in soil. However,in field tests, sethoxydim did not leach below the top 4 inches of soil, Advanced GeoEnvironmental,Inc.
