Breakthrough Green Technology for Preserving Potatoes during Storage
NEWPORT BEACH, Calif.--(Business Wire)--
American Vanguard Corporation (NYSE:AVD) announced that its wholly owned
subsidiary, AMVAC Chemical Corporation (AMVAC), has received registration from
the Environmental Protection Agency (EPA) for SmartBlockĀ®, a novel potato sprout
inhibitor. Additionally, Canadian and European registrations have been filed and
these approvals are progressing on schedule. 

SmartBlock features a patented new class of potato sprout inhibitor technology
that represents a breakthrough approach in the treatment of post-harvest
potatoes. The product is a naturally occurring molecule, an FDA-approved direct
food additive and is classified by the EPA as a biopesticide. It offers safe,
comprehensive long-term storage control and requires no capital investment by
customers since it is easily applied using existing equipment. AMVAC will begin
marketing SmartBlock in the United States immediately. 

Eric Wintemute, Chairman and Chief Executive Officer of American Vanguard
commented: "The registration of SmartBlock expands AMVAC`s potato product
portfolio, with offerings from pre-planting through post-harvest storage. It
enables potato storage managers to utilize a novel, efficacious and green
product for sprout control. We anticipate this new approach will be widely
embraced by grocery chains, restaurants and consumer food processors." 

Glen Johnson, Senior Vice-President of AMVAC commented: "This technology was
discovered by researchers at Washington State University (WSU) and has been
developed and tested by AMVAC for over seven years. It is the first commercial
offering to emerge from our new product development pipeline which serves as a
channel for innovative technologies from numerous university and industry
sources. We expect that our development of new technologies will contribute
meaningfully to AMVAC`s future growth in agricultural and specialty pest control

very pleased to have partnered with AMVAC on the SmartBlock technology. As a
result of this very productive and collaborative research relationship,
additional intellectual property was developed which resulted in worldwide
patent protection." 

Eric Wintemute concluded: "After the United States launch, we believe there are
significant additional opportunities for SmartBlock internationally based on its
excellent performance and cost effectiveness. Developing and commercializing
such significant new products is part of our commitment to deliver Yield
Enhancement Solutions worldwide that improve the production of food, fiber and
