Special ReportsUSEPA/Office of Prevention, Pesticides and Toxic SubstancesReregistration Eligibility Decision Document - Mefluidide, EPA 738-R-07-011 (September 2007). The RED summarizes the risk assessment conclusions and outlines any risk reduction measures necessary for the pesticide to continue to be registered in the USA.[Available from, as of July 9, 2018: http://www.epa.gov/pesticides/reregistration/status.htm]
FIFRA-AnforderungenThe Agency has completed its assessment of the dietary (water only), residential, occupational, and ecological risks associated with the use of pesticides containing the active ingredient mefluidide. Food risks are not assessed because there are no food/feed uses of mefluidide. Based on a review of the mefluidide database and public comments on the Agency's assessments for the active ingredient mefluidide, the Agency has sufficient information on the human health and ecological effects of mefluidide to make decisions as part of the reregistration process under FIFRA. The Agency has determined that currently registered uses of mefluidide will not pose unreasonable adverse effects to humans or the environment provided that the risk mitigation measures and label changes outlined in this RED are implementedtherefore, products containing mefluidide are eligible for reregistration if the risk mitigation measures outlined in the document are adopted and label amendments are made to implement these measures. ... Based on its evaluation of mefluidide, the Agency has determined that mefluidide products, unless labeled and used as specified in this document, could result in unreasonable adverse effects on the environment. Accordingly, should a registrant fail to implement any of the risk mitigation measures identified in this document, the Agency may take regulatory action to address the risk concerns from the use of mefluidide. If all changes outlined in this document are incorporated into the product labels, then current risks for mefluidide will be adequately mitigated for the purposes of this determination under FIFRA.As the federal pesticide law FIFRA directs, EPA is conducting a comprehensive review of older pesticides to consider their health and environmental effects and make decisions about their continued use. Under this pesticide reregistration program, EPA examines newer health and safety data for pesticide active ingredients initially registered before November 1, 1984, and determines whether the use of the pesticide does not pose unreasonable risk in accordance to newer safety standards, such as those described in the Food Quality Protection Act of 1996. Pesticides for which EPA had not issued Registration Standards prior to the effective date of FIFRA '88 were divided into three lists based upon their potential for human exposure and other factors, with List B containing pesticides of greater concern than those on List C, and with List C containing pesticides of greater concern than those on List D. Diethanolamine mefluidide is found on List B. Case No: 2370
Pesticide type: herbicide
Case Status: OPP is reviewing data from the pesticide's producers regarding its human health and/or environmental effects, or OPP is determining the pesticide's eligibility for reregistration and developing the RED document.
Active ingredient (AI): diethanolamine mefluidide
Data Call-in (DCI) Date(s): 02/04/91
AI Status: The producers of the pesticide have made commitments to conduct the studies and pay the fees required for reregistration, and are meeting those commitments in a timely manner.

Unerwünschte WirkungenNeurotoxin - Other CNS neurotoxin
ToxizitätsübersichtIDENTIFICATION AND USE: Mefluidide-diolamine is a plant growth regulator and pesticide. HUMAN STUDIES: There are no data available. ANIMAL STUDIES: Mefluidide-diolamine was not dermally toxic when tested in rabbits at doses of 1000 mg/kg/day for 21 days. Effects were limited to slight erythema at the application site at the 1000 mg/kg/day dose. There were no treatment-related malformations or developmental variations when tested in rats. Clinical signs of neurotoxicity (such as tremors, ataxia, atonia, decreased limb tone, salivation) were seen in several studies (14-day oral in rabbit at or above 200 mg/kg/day, demyelination study in chickens at 1000 mg/kg/day and two developmental toxicity studies in rats at 115 mg/kg/day. Edema and swelling with myelin loss in sciatic nerve was observed in a dermal toxicity study in rabbits at doses of 720 mg/kg and above. However, these effects were not seen in an additional dermal test of similar duration using a 28.8% formulation of mefluidide-diolamine. Mefluidide-diolamine was assayed for induction of reverse mutations at the histidine locus of Salmonella typhimurium tester strains TA98, TA100, TA1535, TA1537 and TA1538 and it was negative with or without metabolic activation. ECOTOXICITY STUDIES: Mefluidide-diolamine was practically non-toxic to rainbow trout (Oncorhynchus mykiss), bluegill sunfish (Lepomis macrochirus), sheepshead minnow (Cyprinodon variegatus, waterflea (Daphnia magna, and to the estuarine marine mysid (Mysidopsis bahia). It was slightly toxic to the estuarine marine eastern oyster (Crassostrea virginica). It was practically nontoxic to honeybees on an acute contact basis. In plants symptoms of toxicity included stunting, chlorosis, necrosis and distortion.
