E.I. du Pont de Nemours & Company's Agricultural Products Department was responsible for the research, development, and manufacturing of organic fertilizers, herbicides, fungicides, insecticides, and other agricultural chemicals. The records include a history of the department, chronology of the benzimidazole fungicide development, history of the technical development of Benomyl, and a small collection of papers from Ralph K. Iler (1909-1985) describing the department's fundamental research program on inorganic chemistry.

George Levitt (1925-), a DuPont Company chemist working at the Experimental Station, discovered sulfonylurea (SU) herbicides in 1976 after two decades of experimentation. This collection consists of six of Levitt's laboratory notebooks documenting milestones in herbicide discovery.
