Several pesticides play a vital role in the production of many agricultural crops. Of particular importance at this time are the Organo-phosphates, carbamates, and possible carcinogens (B1's and B2's). These classes of pesticides have been identified as top priority at EPA for the tolerance reassessment process. Because some of these uses may be modified or canceled, it is important to identify where we stand now and where we need to be in the future. Thus, the Food Quality Protection Act instructed USDA and EPA to obtain pesticide use and usage data on the major and minor crops.
To help USDA and EPA obtain this type of information, "Crop Profiles" are being developed. It is the intent that profiles provide the complete production story for a commodity and a look at current research activities directed at finding replacement strategies for the pesticides of concern. Crop Profiles include typical use information (not simply what pesticide labels state) and have a common format for ease of use. In general, information collected for a crop profile includes:
Cultural practices, and worker activities that occur during the growing season
Pests (insects, mites, diseases, weeds and others), and pest control agents (including alternatives and non-chemical methods)
Chemical control (rate applied, method of application, number of applications, pre-harvest intervals, crop price/unit for use in assessing pesticide usage, application methodology, and comparative product performance in agricultural production systems in the state)
Biological controls
Comments with regard to possible replacement strategy
Currently there are more than 500 crop profiles on the web (www.pmcenters.org).
