FOR IMMEDIATE RELEASE

AMERICAN VANGUARD TO ACQUIRE ONE PLANT AT BASF’S HANNIBAL, MO SITE

Newport Beach, CA – October 29, 2007 – American Vanguard Corp. (NYSE:AVD) today announced that it has exercised an option to acquire one plant at BASF Corporation’s Hannibal, MO site that manufactures two of American Vanguard’s most important and promising insecticide products. This pertains to only one of the five plants at BASF’s Hannibal site.

The Company anticipates growing sales of Phorate^® (acquired in 2005) and Counter^® (acquired in 2006) in coming years, and exercising the asset purchase option associated with those prior product acquisitions ensures the continuing supply of these high-quality insecticide products for use in a wide variety of agricultural applications. This acquisition, which is expected to close in late December 2007, will significantly increase American Vanguard’s organophosphate manufacturing capacity.

Eric Wintemute, CEO of American Vanguard, commented, “We are pleased to be taking ownership of these extremely valuable production assets. The Midwest location will provide us with significant operational and logistical benefits as we continue to expand our participation in the U.S. corn market.

“Our operation will continue to utilize the substantial infrastructure provided at this plant site, including its comprehensive waste treatment capabilities. BASF’s regimented regulatory compliance and environmental stewardship was a prime factor in our decision to purchase these assets.”

Wintemute continued, “This purchase, along with our 2002 purchase of a DuPont facility in Alabama, demonstrates American Vanguard’s commitment to expanding our world-class domestic manufacturing capabilities. We believe that such North American production units provide a level of quality assurance, expedited delivery and overall cost effectiveness that is superior to those offered by many offshore producers. We intend to use this competence to better serve our existing customers and to facilitate increased future output as we expand our sales channels in international markets.”
