Tolerance Reassessment Decision (TRED) for Low Risk Pesticide; Notice of Availability.
The following is from the HED Risk Assessment for the Tolerance Reassessment Eligibility Document (TRED).
-- Flumetsulam is in the triazolopyrimidine chemical class and has a mode of action similar to the sulfonylurea herbicides that are acetolactate synthase inhibitors (regulate plant growth).
-- The kidney appears to be the primary target organ of rats and dogs following subchronic to chronic exposures.
-- A neurotoxicity study was not conducted, however, flumetsulam showed no indication of being a neurotoxicant in the reviewed studies.
-- A 90-day inhalation study and a subchronic dog study were not conducted, but it is doubtful these would provide any additional useful information.
-- A developmental neurotoxicity study is not required since there was no evidence of neurotoxicity or neuropathy from the available studies.
-- Due to the lack of repeated dose inhalation toxicity study, oral studies were selected for the appropriate duration of exposure. Absorption via inhalation is assumed to be equivalent to oral absorption.

DOW ELANCO - Pesticide Tolerance. Final Rule. This rule establishes a tolerance for residues of the new herbicide flumetsulam in or on the raw agricultural commodities corn, field, grain; corn, field, fodder; corn, field, forage; and soybeans at 0.05 ppm. This regulation was requested by DowElanco. This regulation becomes effective on October 28, 1993. Note: The Fed. Reg. does not have online access to its 1993 publication; the PMEP at Cornell U. is the source of this notice.
