The Penn-Del IPM Research Group (first known as the Southeast Pennsylvania IPM Research Group) was established in May of 1990 with 11 members and during its existence grew into a multi-state group with almost 30 members. It was a collaboration between Pennsylvania Cooperative Extension and ornamental people in the southeast part of the state.

Penn State Extension and Delaware Cooperative Extension provide administration and technical support while the ornamental people provide the research data. The members are called cooperators. The cooperators directly influence what research and educational programs are carried out.
