Description: The California Department of Food and Agriculture completed a three-phase study in 1988 to investigate the environmental fate of methyl eugenol, naled, and dichlorvos (DDVP), a degradation product of naled. The first phase of the study was planned to determine the feasibility of monitoring the three compounds during a routine pest eradication program. Once the feasibility of monitoring the three compounds was shown, the second-phase was planned to measure ambient air concentrations of the compounds during a fruit fly eradication. The third-phase was planned to determine if residues of methyl eugenol, naled, and DDVP were present in edible portions of fruit growing near fruit fly traps

Description: A well sampling survey was conducted to determine the presence of fenamiphos, fenamiphos sulfoxide, and fenamiphos sulfone in ground water. Wells were sampled in areas where use of fenamiphos coincided with areas of previous contamination by other pesticides, This was possible because fenamiphos is a restricted use pesticide so a spatial record of use was available and the CDFA’s Well Inventory Data Base contains spatial locations of historical pesticide detections in well water. Twenty-four wells were sampled in 16 sections in Fresno County, 12 wells were sampled in 8 sections in San Joaquin County and 5 wells were sampled in 3 sections in Kern County. No residues of fenamiphos or its sulfoxide and sulfone metabolites were detected in any of the samples.

Description: The California Department of Food and Agriculture (CDFA) conducted an eradication program for gypsy moth in spring, 1990 which treated two small areas with the insecticide diflubenzuron. CDFA’s Environmental Hazards Assessment Program (EHAP) collected foliage, air, water, and tank mix samples to monitor environmental concentrations of diflubenzuron resulting from these treatments. Both the eradication and monitoring programs were similar to those conducted for the Gypsy Moth program in Los Angeles County in 1987. The objective this year was to monitor applications and compare results with those found in 1987, not to provide a detailed characterization of diflubenzuron degradation.
