AMERICAN VANGUARD REPORTS SECOND QUARTER 2008 RESULTS

Strong Quarterly Performance Reflects International Expansion, New Product Additions and Specialty

Product Strength

Newport Beach, CA – August 7, 2008 – American Vanguard Corporation (NYSE:AVD), today announced financial results for the second quarter and six month period ended June 30, 2008.

Fiscal 2008 Second Quarter Financial Highlights – versus Fiscal 2007 Second Quarter

• Net sales increased 16% to $57.9 million.

• Net income grew 21% to $4.3 million.

• Earnings per diluted share increased 23% to $0.16.

Fiscal 2008 First Half Financial Highlights – versus Fiscal 2007 First Half

• Net sales increased by 9% to $98.8 million.

• Net income improved by 6% to $6.1 million.

• Earnings per diluted share were $0.22, versus $0.21.

Eric Wintemute, President and CEO of American Vanguard, stated: “We are very pleased with the strong second quarter performance, which reflects strength in our international business, the benefits of recent product acquisitions and the expansion of our non-crop specialty products segment. Sales in most major agricultural end-uses met expected levels, and our initiatives to gain larger positions in some of our key markets are progressing. Results continue to be influenced by rising raw material costs, utility rates and fuel costs. We continue to address these cost increases by focusing on internal cost savings, efficiency improvements and where necessary, raising product prices to maintain appropriate profit margins.”

Among the most important performance highlights:

• Solid continuing sales of our soil fumigant products, and a good performance of our recently acquired fungicides and insecticides, contributed to a strong quarterly sales performance for the Company.

• Our international sales continued to grow in the second quarter with substantial sales gains in Mexico. Central and South America offer excellent opportunities for us, and we are establishing a physical presence in Costa Rica to support regional growth for the future.

• Our non-crop specialty products sales grew strongly during the second quarter, due to the seasonal placement of our mosquito adulticide product line and further penetration of the turf and ornamental market segment.

• Sales of our main cotton protection products exceeded the prior year’s sales, although full-year sales will likely remain soft due to reduced forecast cotton acreage.

• After achieving higher than expected sales of our corn herbicide Impact^® in the first quarter, demand fell short of our internal expectations in the second quarter. Nevertheless, we continue to witness superior in-field performance and increasing grower recognition of this product.

Mr. Wintemute concluded, “We remain optimistic about our prospects for the balance of 2008 and for the 2009 North American spring planting season. Over the next several quarters, we expect to further strengthen our international presence in existing markets and expand into new markets; achieve improved acceptance of our

herbicide and insecticide offerings in corn; experience solid demand in most of our primary end-use crop markets; and introduce new products in our non-crop segment for professional pest management. We will be taking initiatives to better exploit our North American manufacturing capability, producing products that are complex to manufacture and in which we have a demonstrated track record.”
