NEWPORT BEACH, Calif.--(Business Wire)--
American Vanguard Corporation (NYSE:AVD) today announced that it has completed
an investment in TyraTech, Inc. to participate in the continued development and
marketing of natural products for human and animal health applications. American
Vanguard has invested $3.7 million to secure a 29.46% ownership position in
TyraTech, Inc. 

American Vanguard`s equity investment achieves an important strategic objective
by expanding its involvement in the development of products derived from natural
sources and by participating in the penetration of such technologies in
non-agricultural market segments. TyraTech has developed more than a dozen
unique products that show efficacy as mosquito, fly, flea and tick repellents,
head lice control treatments and intestinal parasitic control agents. Several of
these products which are expected to be commercialized during 2013 and 2014
demonstrate performance characteristics that are superior to existing,
commercially available, offerings. The global addressable market potential for
such applications is estimated to be in the range of $8 to 10 billion annually. 

This investment follows the December 2012 creation of Envance Technologies, LLC
between AMVAC-Chemical Corporation (a wholly-owned subsidiary of American
Vanguard) and TyraTech, Inc. for the purpose of developing and commercializing
best-in-class technologies for the global consumer household and lawn & garden
retail markets. Envance Technologies, which is majority owned by AMVAC-Chemical,
already has its first commercial product line, Terminix Ultimate Protection, on
the shelves of a major U.S. retail home improvement chain. The global
addressable market potential for such products is estimated to be between $3.5
and 4.5 billion annually. Envance also expects to develop new combinations of
natural and synthetic compounds using TyraTech`s patented Extend Technology. 

Eric Wintemute, Chairman & CEO of American Vanguard Corporation commented: "This
investment solidifies our commitment to the development and commercialization of
effective human and animal health products derived from natural sources.
American Vanguard`s existing non-crop business addresses mosquito and
general-purpose commercial pest control with a proven chemical product
portfolio. TyraTech`s advanced technology and product formulations deploy
natural defenses for individual protection from many threats that can compromise
human and animal health. Our ownership stake in TyraTech joins us in a very
complementary mission, with a clearly aligned mutual interest in safeguarding
both public and personal health." 

Alan Reade, Executive Chairman of TyraTech, Inc, commented: "The commitment and
support of American Vanguard gives confidence in our strategy and credence to
our belief that we are in the right markets with the right products. We are
seeing a significant and growing desire for products which are natural, safer
and more effective within our markets and we aim to be at the forefront of this
transformational shift in demand. We are most grateful for American Vanguard`s
support, which provides a solid foundation from which we can build the TyraTech
