Isocycloseram; Pesticide Tolerance for Emergency Exemption

This regulation establishes a time-limited tolerance for residues of isocycloseram, including its metabolites and degradates, in or on sunflowers. This action is in response to EPA's authorization of a specific exemption under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) authorizing use of the pesticide on sunflowers. This regulation establishes a maximum permissible level for residues of isocycloseram in or on sunflower, seed at 0.4 parts per million. The time-limited tolerance expires on December 31, 2029.
