Adverse Effects

Return to Flumetralin Index Page

Activity: Plant growth regulator (2,6-Dinitroaniline)

Adverse Effects:

• European Commission: Not allowed to be used as an active ingredient after July 25, 2003.

• The pesticide Prime+ @ is 15% Flumetralin and 85% solvent system. It is produced by Ciba, Ltd. to control axillary bud (sucker) growth after the floral portion of tobacco plants have been topped. Prime+ is absorbed by the tobacco plant within a few hours after application and provides residual sucker control through the growing season. US EPA does not conduct toxicological studies on tobacco pesticides. No toxicological data is available.

Rationale for US EPA to add Flumetralin to the Toxic Release Inventory: Aquatic acute toxicity values for flumetralin include a daphnid 48-hour EC 50 of greater than 2.8 ppb, a bluegill sunfish 96-hour LC 50 of greater than 3.2 ppb, and a rainbow trout 96-hour LC 50 of greater than 3.2 ppb.
EPA believes that there is sufficient evidence for listing flumetralin on EPCRA section 313 pursuant to EPCRA
section 313(d)(2)(C) based on the available environmental toxicity data for this chemical.
