In Depth
Grasselli was a long-time manufacturer of inorganic and organic insecticides and became the umbrella organization when DuPont consolidated its scattered biochemicals businesses during the late 1940s. Despite some early financial and technical setbacks Grasselli expanded its inorganic operations during the next decade to serve 20 percent of the U.S. herbicide market with its substituted urea products. In 1959 the Grasselli Chemicals Department was reorganized into the Industrial and Biochemicals Department.
