Delaware researchers receive award for 'greener' herbicide production

May 20, 2002

A team of chemists, biologists and engineers from DuPont in Wilmington, Del., will be honored May 29 by the world's largest scientific society for developing a "greener" way to produce a new herbicide. They will receive one of three 2002 Industrial Innovation Awards at the American Chemical Society's Middle Atlantic regional meeting in Fairfax, Va.

"Multidisciplinary teams will be the main force driving the development of the products, materials and technologies that advance civilization in the 21st century," said Eli Pearce, president of the American Chemical Society. "Individual members of the team share knowledge to achieve a common goal, achieving more than each could alone. Thus, the team becomes a whole that is greater than the sum of its parts."

The new process -- which uses microorganisms to convert one chemical into another -- eliminates the use of the harmful chemical toluene and generates less waste. The herbicide, called Milestone® (azafenidin), inhibits weeds' ability to make chlorophyll and controls many annual broadleaf weeds and grasses found in citrus, grape and sugarcane crops.

The American Chemical Society's Industrial Innovation Awards recognize individuals and teams whose discoveries and inventions contribute to the commercial success of their companies and enhance our quality of life.

NOTE TO REPORTERS: The winners will present 20-minute talks about their work on Wednesday, May 29, from 2:30-5 p.m. If you would like to attend the awards banquet or presentations, please contact the person listed above.
