## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of the zucchini yellow mosaic virus-weak strain (ZYMV-WK) on cucurbits, including, cucumbers, cantaloupes, watermelons, muskmelons, winter and summer squash, pumpkins, zucchini and other cucurbits when applied/used as a viruscide to protect curcurbit crop plants against severe strains of zucchini yellow mosaic virus. Bio-Oz Biotechnologies Limited submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), as amended by the Food Quality Protection Act of 1996 (FQPA), requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of ZYMV-WK strain.
