## Abstract

This regulation extends a time-limited tolerance for combined residues of the insecticide imidacloprid (1-[6-chloro-3- pyridinyl)methyl]-N-nitro-2-imidazolidinimine) and its metabolites containing the 6-chloropyridinyl moiety, all expressed as 1-[(6-chloro- 3-pyridinyl)methyl]-N-nitro-2-imidazolidinimine in or on cucurbits (Crop Group 9 including cucumbers, melons and squash) at 0.2 part per million (ppm) for an additional 1-year period. This tolerance will expire and is revoked on March 31, 2000. This action is in response to EPA's granting of an emergency exemption under section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) authorizing use of the pesticide on cucurbits. Section 408(l)(6) of the Federal Food, Drug, and Cosmetic Act requires EPA to establish a time-limited tolerance or exemption from the requirement for a tolerance for pesticide chemical residues in food that will result from the use of a pesticide under an emergency exemption granted by EPA under FIFRA section 18.
