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 Agricultural Products Department traces its origins to the Grasselli Chemical Company, which was acquired by the DuPont Company in 1928. It became the Grasselli Chemicals Department in 1936 and the Industrial & Biochemicals Department in 1959. It was divided into separate Industrial Chemicals and Biochemicals Departments in 1972. The Biochemicals Department was renamed the Agricultural Chemicals Department in 1983 and the Agricultural Products Department in 1985. During the 1920s and early 1930s, the department concentrated on developing organic fertilizers. In the 1940s and 1950s, its focus shifted to herbicides, feed supplements for chicken and cattle, fungicides, and insecticides. During the Second World War, the department developed DDT. During the 1960s and 1970s, the worldwide market for agricultural chemicals grew substantially, and this department became an important profit center within the company.
