Item 8.01 Other Events

On December 19, 2006, American Vanguard Corporation’s wholly owned subsidiary, AMVAC Chemical Corporation, completed the acquisition of certain assets comprising the product line Permethrin (a synthetic pyrethroid insecticide) from Syngenta Crop Protection, Inc. In connection with the transaction, AMVAC acquired both crop and non-crop uses of the product line in the U.S., Mexico and Canada. Acquired assets include registration rights, manufacturing and formulation know-how, inventories, customer lists and the trademarks Ambush^® and Prelude^® in the aforementioned territories.

In July 2002, AMVAC acquired from Syngenta certain assets associated with the Ambush 25WP (wettable powder formulation) insecticide business in the U.S., and now owns the complete Permethrin product line. This product line sells into an estimated $40 million market and can be used on essentially all fruit and vegetable crops to control a broad spectrum of insect pests.

AMVAC will begin selling the Permethrin products immediately. The Company will be re-launching the liquid formulation of Ambush, which has one of the broadest lists of crops on its label, in the U.S. and Canada, as Syngenta has not sold it into those marketplaces for the past four years. In Mexico, AMVAC will distribute Ambush through national distributors. Sales of Prelude, which is sold for general pest control in or around the home, have been ongoing in both the U.S. and Canada and will continue with existing distributors.
