31 August 2004 AGE-NC Project No.04-1188 Page 12 of 24 insecticide which is used on a wide range of pests such as moths, flies, beetles, and other insects. It is moderately toxic by ingestion, slightly toxic by dermal and nontoxic by inhalation exposure. It is not considered to be mutagenic, carcinogenic or teratogenic at expected doses. Under field conditions,esfenvalerate is moderately persistent with a half-life ranging from about 15 days to three months depending on soil type.Esfenvalerate and its breakdown products are relatively immobile in soil and thus pose little risk to groundwater. The compounds ability to bind to soil increases with increasing organic matter. Esfenvalerate will break down in water to one-half of the original amount (half-life) in about twenty-one days due to sunlight. AVAUNT INSECTICIDE: AVAUNT is a water dispersible granule that can be applied as a foliar spray to control many important insects.Avaunt is slightly toxic by ingestion,inhalation and dermal exposure. It is not considered to be mutagenic, carcinogenic or teratogenic at expected doses. This pesticide is considered toxic to mammals,birds, fish and aquatic invertebrates. BANVEL (dicamba): A General Use Pesticide (GUP). Dicamba is a benzoic acid herbicide that can be applied to the leaves or to the soil to control annual and perennial broadleaf weeds in grain crops and grasslands. Dicamba is slightly toxic by ingestion(causes anemia) and slightly toxic by inhalation or dermal exposure. It is not considered to be mutagenic, carcinogenic or teratogenic at expected doses. Dicamba is moderately persistent in soil. The half-life in soil is typically 1 to 4 weeks; under conditions suitable for rapid metabolism, the half-life is less than 2 weeks. Metabolism by soil microorganisms is the major pathway of loss under most soil conditions.The rate of biodegradation increases with temperature and increasing soil moisture, and tends to be faster when soil is slightly acidic. It is stable to water and other chemicals in the soil and it does not bind to soil particles and is highly soluble in water;it is therefore highly mobile in the soil and may contaminate groundwater. ... In water,microbial degradation is the main route of dicamba disappearance. BRAVO ULTREX(Chlorothalonil): This compound is a General Use Pesticide(GUP)in toxicity class H and must carry the label WARNING. Chlorothalonil is a broad-spectrum organochlorine fungicide.It is considered harmful by ingestion,inhalation and dermal exposure but has no suspected teratogenic, carcinogenic or mutagenic effects in humans. Chlorothalonil is moderately persistent in soil; in aerobic soils, the half-life is from 1 to 3 months. Increased soil moisture or temperature increases chlorothalonil degradation; it is not degraded by sunlight on the soil surface. Chlorothalonil has high binding and low mobility in silty loam and silty clay loam soils, and has low binding and moderate mobility in sand. In very basic water(pH 9.0), about 65% of the chlorothalonil was degraded into two major metabolites after 10 weeks. Advanced GeoEnvironmental,Inc.
