NEWPORT BEACH, Calif. -- April 22, 2013

American Vanguard Corporation (NYSE:AVD) today announced that a member of its
Board of Directors, Esmail Zirakparvar has received the Distinguished Alumni
Award from his alma mater, Iowa State University. This award is the highest
honor given to alumni by Iowa State’s Alumni Association and has been
presented annually since 1961 to individuals who are nationally and/or
internationally recognized for preeminent contributions to their professions
or life's work.

Mr. Zirakparvar has left a visible mark on the agrichemical industry since
beginning his career in agribusiness and plant biotechnology at Iowa State in
1975 when he arrived from Iran to begin graduate studies. He trained in the
field of nematology, earning both a master’s and a Ph.D. in plant pathology,
and his research discovered the first known presence of soybean cyst nematode
in Iowa.

Mr. Zirakparvar went on to manage agribusinesses for Union Carbide,
Rhone-Poulenc Agro, Aventis CropScience, and Bayer CropScience. As board
member and COO of Bayer CropScience, Mr. Zirakparvar played a key role in the
formation of the company following the merger of the agricultural businesses
of Aventis and Bayer in 2004. Under his leadership, Bayer CropScience grew to
become one of the world’s leading innovative companies in the area of crop
protection, non-agricultural pest control, and seed and plant biotechnology.
After retiring in 2006, he has been part of Precision BioScience’s advisory
board since 2007, and in 2010 he joined American Vanguard Corporation as a
member of its Board of Directors.

Eric Wintemute, Chairman & Chief Executive Officer of American Vanguard
commented: “Esmail has been a very valuable addition to our Board over the
past several years. His tremendous international experience allows him to
contribute significantly to our analysis of global agribusiness opportunities.
His insights into the technological aspects of agriculture and pest control
have aided us in strategic and acquisition decision-making. We are delighted
to see him receive this well-deserved honor for his great contributions to our
Industry’s efforts to feed a growing and hungry global population.”
