Evaluation of Fungicides for the Control of Gray/White Mold in Snap Beans

The processed vegetable industry has struggled annually with EPA to secure the Ronilan label. EPA announced that the registration will be cancelled in September 30, 2005. There are a number of new fungicides that have not been evaluated for the control of either Botrytis or Sclerotina for snap beans in Oregon. The currently registered alternative fungicides to Ronilan; Benlate, Bravo, Topsin, and Royal, are all subject to review by the EPA under the guidelines set forth in the provisions of the 1996 Food Quality Protection Act.
