Drought Conditions in Ohio as of October 2, 1999

Minor Use Pesticides Prioritized in 1999 IR-4 Food Use Workshop

Due to the current review of crop protection chemicals under the Food Quality Protection Act and the high cost to industry of product registration, minor crops are at risk of having fewer products available for weed, insect pest, and disease control. To mitigate this problem, IR-4 (USDA Interregional Research Project No. 4) facilitates pesticide registration of minor crops by funding residue trials, and more recently, efficacy and phytotoxicity trials.

Priorities for the year-2000 research program for most fruits, vegetables, and herbs grown in the U.S. were assigned at the 23^rd Food Use Workshop held August 25-27 in Denver, Colorado. The workshop was attended by minor crop researches; extension specialists; growers; representatives of commodity groups and industry; and personnel from EPA, USDA, and IR-4. A total of 142 attendees participated in the workshop and a total of 559 potential research projects were reviewed.

Participants were provided with lists of new or soon-to-be-registered pesticides, and they were asked to rank products based on need, performance, safety, and availability and efficacy of alternatives. A limited number of projects could be assigned "A" or "B" priority. An "A" priority allows IR-4 to begin research immediately for submission of data to EPA scheduled for 2002. "B" priority projects are funded as resources permit. Projects with a "C" or "D" rating are not likely to get funding.

Priority "A" and "B" projects are listed in the accompanying table. Many of these compounds are considered "reduced-risk," which means they have low mammalian and environmental toxicity. In addition, biocontrol and systemic-induced resistance (SAR) products, like Serenade and harpin, respectively, are featured.
