DPR Director Testifies that the Department’s Proposed Registration Decision on Methyl Iodide is More Health Protective than U.S. EPA’s Decision

SACRAMENTO – Department of Pesticide Regulation (DPR) Director Mary-Ann Warmerdam will describe how the department reached its proposal to register methyl iodide during an informational legislative hearing today called by state Sen. Dean Florez (Shafter). Warmerdam will testify that DPR’s proposed health protective measures are more stringent than the U.S. Environmental Protection Agency’s and 47 other states that have already registered methyl iodide. The hearing is scheduled at 2 p.m. in the State Capitol in room 3191.

Warmerdam announced on April 30 the proposal to register the new fumigant following an extensive scientific review. U.S. EPA registered methyl iodide in 2007 as a replacement for methyl bromide. Pesticides must be registered by both U.S. EPA and DPR before they can be used in California.

Warmerdam will describe the process of making a risk management decision that takes many factors into account.

"I look forward to explaining how we determined methyl iodide can be used safely with a comprehensive list of use restrictions based on our scientific risk assessment and other information," she said. "DPR’s proposed buffer zones, lower allowable exposure levels, reduced application rates per acre and other controls are much more health-protective than those required by U.S. EPA and in any other state."

DPR is accepting public comments on its proposal until June 29, 2010. More information about its proposal and how to submit comments is available at


One of five departments and boards within the California Environmental Protection Agency, DPR regulates the sale and use of pesticides to protect people and the environment.
