MAY JOINT DE ACS/CHEMVETS LECTURE
" Building an Innovative Culture: Discovery of Modern Crop Protection Chemicals"
Dr. George Lahm
Date: May 15, 2018
Time: 5 p.m. – 6:30 p.m.
Location: DuPont Country Club
The discovery, development and commercialization of modern crop protection
chemicals involves a complex matrix of study spanning diverse fields of science
and engineering. The industry is driven through innovation owing to a continuing
need to discover and develop new products that preferentially act through new
biochemical mechanisms. The standards are necessarily high to meet societal and
regulatory demands of efficacy and safety to people and the environment. This
requires an integrated process that begins with identification of molecular starting
points and proceeds through the optimization of all properties associated with
efficacy and safety. This presentation will describe this process and the associated
challenges required to successfully bring the product from idea conception through
to commercialization. Recent commercial successes including Rynaxypyr® and
Cyazypyr® will be used to demonstrate some of the problems encountered, lessons
learned, and solutions achieved.
George P. Lahm, FMC Distinguished Scientist, obtained his B.S. in chemistry from the State University of New York, Oswego in 1976 and his Ph.D. in organic chemistry from Indiana University under Professor Richard M. Jacobson. In 1980, he joined DuPont as part of the Crop Protection Discovery group and in 2017 he moved to FMC Agrictural Solutions. His thirty-sevenyear career has focused principally on the discovery and development of new products for insect control.
Dr. Lahm’s research in new products for insect control
set the stage for the discovery of the novel sodium
channel blocker, indoxacarb, the new ryanodine
receptor activators chlorantranilprole and cyantraniliprole
and the new nematicide fluazaindolizine. These products
represent landmarks for the protection of food
crops, demonstrate outstanding field efficacy,
environmental compatibility, and low toxicity to
Dr. Lahm has a patent record of over 60 U.S. and internationally filed patents. He was a recipient of the 2003 ACS Team Innovation Award for the discovery of indoxacarb and the 2009 recipient of the ACS Spencer Award for outstanding achievement in agricultural and food chemistry. He was a recipient of DuPont honors including the 2004 Pedersen Medal for scientific achievement and three BoltonCarothers corporate team awards. In 2010, he was awarded the Lavoisier medal, DuPont’s highest technical award for lifetime contributions, and in the same year he was appointed to DuPont’s highest technical level, DuPont Distinguished Scientist. In 2011, he received the American Chemical Society’s International Award for Research in Agrochemicals and in 2018 he was the recipient of the ACS Award for Industrial Chemistry.
George and his wife Louise have two children and two grandchildren and reside in Delaware.
