IPM Commodity Working Groups

The four IPM commodity working groups help the IPM Program organize its long-range plans, identify priorities for and evaluate proposals made to its grants program, and encourage teamwork among the scientific disciplines at Cornell University. The vegetable implementation group is a subcommittee that coordinates and makes funding decisions on vegetable IPM implementation projects.
