Pesticide News Story: EPA’s Proposes to Terminate Special Review for Dichlorvos (DDVP) – Open Comment Period until October 26, 2007
For Release: September 28, 2007
In a Federal Register Notice published on September 26, 2007, EPA is proposing to terminate Special Review for the pesticide Dichlorvos (DDVP) an insecticide and fumigant of the organophosphate class of pesticides. When the DDVP Special Review was initiated in 1988, EPA identified concerns for cancer and liver effects as well as cholinesterase inhibition. Through the Agency’s comprehensive reregistration process, the Agency resolved the concerns regarding cancer and cholinesterase effects.
Specifically, in 2006, the Agency completed an intensive review culminating in an Interim Reregistration Eligibility Decision (IRED). EPA determined that the few remaining uses of DDVP do not present risks that exceed levels of concern, and therefore no additional risk mitigation measures were necessary. Many uses of DDVP in and around the home are no longer permitted. In sum, based on the IRED, the requested label amendments, and the voluntary cancellation of uses by the registrant, EPA has determined that the risks that were the basis of the Special Review are no longer of concern and, therefore, the Agency is proposing to terminate the Special Review of DDVP.
The Agency notes that it has received and is in the process of responding to a petition to cancel all DDVP registrations and revoke all DDVP tolerances. The breadth and scope of the petition is far greater than the discrete issues that were the triggers initiating the DDVP Special Review. The Agency is proposing to terminate the Special Review, and to assess the merits of the petition separately. Notwithstanding anything in this proposal or in the reregistration decision for DDVP, if EPA determines that some or all of the petition should be granted, the Agency will pursue appropriate changes to the terms and conditions of DDVP registrations.
DDVP is registered for use in controlling flies, mosquitoes, gnats, cockroaches, fleas, and other insect pests. Formulations of DDVP include pressurized liquids, emulsifiable concentrates, and impregnated materials. DDVP is applied with aerosols and fogging equipment, with spray equipment, and through slow release from impregnated materials, such as resin strips. DDVP is also registered to control insect pests on agricultural sites; commercial, institutional and industrial sites; and for domestic use in and around homes (i.e., resin strips).
