About Us

AgBioChem, Inc. was created in 1975 to provide growers with tools to control crown gall disease.  AgBioChem was first to obtain U.S. EPA registration for the crown gall-preventative bacterium contained in GALLTROL-A and, in 1976, first to bring this important bio-control agent to market.  In 1977, AgBioChem registered GALLEX (a University of California invention) and made it available to growers.  GALLEX is the only product ever registered by EPA for eradication of existing galls.  Nearly forty years later, GALLTROL-A and GALLEX remain the most effective crown gall control products and continue to be widely used by growers across the United States and elsewhere.  AgBioChem is a small,  family-owned corporation whose sole purpose is to provide to growers the best available crown gall control products.
