FOR IMMEDIATE RELEASE

AMERICAN VANGUARD SCHEDULES 2009 EARNINGS RELEASE AND CONFERENCE CALL

FOR MONDAY, MARCH 8^TH

Newport Beach, CA – February 22, 2010 – American Vanguard Corporation (NYSE:AVD), today announced that it will report financial results for the 2009 fourth quarter and full year on Monday, March 8, 2010 before the stock market opens. The Company also expects to file its 10-K with the Securities & Exchange Commission not later than March 12, 2010.

Eric Wintemute, President and CEO of American Vanguard, stated: “Challenging industry-wide conditions in the agricultural chemical marketplace during mid & late 2009 resulted in a revenue decline for American Vanguard in the fourth quarter and for the full year. Soft grower demand caused reduced inventory stocking by distributors, which compelled us to curtail our own manufacturing production to deal with this temporary market reality.”

“The combination of sluggish sales demand and the impact of unabsorbed fixed manufacturing costs have resulted in financial performance well below our expectations during the fourth quarter. We have responded by intensifying our sales & marketing initiatives, reducing costs throughout the Company and accelerating our efforts to develop and introduce new products.”

Mr. Wintemute continued: “We are making significant progress on our stated balance sheet objectives. During the final quarter of 2009, we reduced our inventory level by 13% (excluding the write downs and adjustments referenced below), maintained our diligence in receivables collection and generated enough cash to pay down our bank revolver credit facility by over 90%. Additionally, during the year-end assessment of our inventory, we determined that it was appropriate to write down the value of certain items by way of a one time, non-cash charge in the range of $12 million to $15 million. This charge arises primarily from the effect of unabsorbed manufacturing overhead activity, net realizable value assessments of slow-moving and obsolete inventory, and finally, other annual adjustments to ensure that our standard costs continue to closely reflect actual manufacturing cost. This charge is expected to have an after-tax impact of $7 million to $9 million and lead to a quarterly loss of between $.25 and $.33 per share.”

Mr. Wintemute concluded, “Our management team is concentrating its full attention on improving our operating performance through organizational upgrades, streamlined manufacturing processes, administrative cost constraint and an enhanced emphasis on the introduction of new products. These important initiatives will be discussed during our March 8^th conference call. We are positioning ourselves to capitalize on improvements in the marketplace while maintaining our focus on balance sheet strength.”
