Summary:
Many commonly used crop protection chemicals, including highly toxic, broad-spectrum, long residual, organophosphate and carbamate insecticides, certain fungicides that are possible human carcinogens, and other pesticides with estrogenic effects, are now thought to represent a significant risk to human health, to beneficial natural enemies and other non-target organisms and to the environment. The passage Food Quality Protection Act (FQPA), raised the prospect that future pest management systems may be far less reliant on these relatively inexpensive, but often riskier materials. To help growers prepare for such an possible outcome, it is critical for the public sector to develop, test and analyze innovative, economically viable pest management programs that use lower risk pesticides in the context of an IPM strategy. Only when such systems are fully characterized and demonstrated to be both affordable and effective, can we anticipate that growers will willingly adopt them.
The proposed project would be in keeping with USDA's and EPA's current emphasis on risk measurement and reduction, as described in the USDA "IPM Roadmap". The project is consistent both with an IPM Working Group (IWG) Priorities grant and with a Critical/Emerging Issues grant. The team will work collaboratively with private sector partners to describe the current standard integrated management (SIPM) system for New England apples using Crop Profiles and input from growers, along with a reduced risk IPM (RRIPM) system. The SIPM protocol will involve choice of material, rates and frequency of application by cooperating growers based solely on efficacy and cost. RRIPM protocols will involve deliberate choice of materials that either are considered "low risk" by EPA, or are determined to be so using as a model the Benbrook et al. multi-attribute toxicity rating. Potential dermal and inhalation exposure to various organophosphate, pyrethroid and carbamate pesticides on the part of researchers conducting typical worker and/or IPM scout activities will be determined utilizing dosimetry (i.e., residues on cotton suits, gloves and air samplers). The experimental design will provide a variety of exposure situations in which we can determine "risk". The dosimetry group will wear cotton long-sleeved shirt, long pants, neck hoods, and gloves as passive collectors for dislodgeable pesticide residues. Inhalation exposure will be measured using personal air sampling pumps with pesticides absorbed onto various sorbents, depending on the pesticide. Sample analyses will be conducted at the Massachusetts Pesticide Analysis Laboratory (MPAL), a USEPA/MA Department of Food and Agriculture (MADFA)-supported FIFRA pesticide analytical laboratory.
