Crop Timelines

FQPA instructs USDA and EPA to obtain pesticide use and usage data on the major and minor crops. Of particular importance at this time are use and usage data for the organophosphates, carbamates, and possible carcinogens. These classes of pesticides have been identified as top priority at EPA for the tolerance reassessment process. These same pesticides are also vital in the production of many of our crops.

Because some of these uses may be cancelled, it is important to identify where we stand now, where we need to be in the future, and what research efforts are needed to get us there. In order to better understand where future research efforts should lead, it is necessary first to identify areas of critical need (i.e., those crops that have few if any alternative control measures available).

To help USDA and EPA obtain this type of information, Crop Timelines are being developed. It is the intent that timelines provide current information on crop phenology, pest occurrence and human activities in the crop. This site is part of the effort by the USDA Integrated Pest Management Centers to provide  information critical to pest management needs in the United States. All of the timelines listed here have been approved by EPA.

Problems or corrections can be addressed to the NSF Center for Integrated Pest Management.
