The Center for Pollinator Research is committed to developing crop-specific best management practices guidelines for "Integrated Pollinator and Pest Management" (IPPM).

We are increasingly aware that some present-day agricultural practices are detrimental to pollinators.  Instead of eliminating these practices, which could decrease agricultural efficiency, these practices can be adjusted to decrease pollinator harm while maintaining agricultural efficiency.  By detailing pesticide effects through research, and then adjusting integrated pest management (IPM) recommendations to incorporate this knowledge, growers can maintain crop protection from pests as well as protect pollinator health.  This IPPM approach has already been successfully applied to orchard crops in the Northeast, and this program can be used as a model for other commodity groups

The recommendation for developing and implementing an IPPM approach was the outcome of a workshop of scientists, stakeholders, and government representatives held at the 2013 International Pollinator Conference at Penn State. We are working together with the Xerces Society and the Penn State Horticulture Extension Team to develop these approaches and disseminate this information to extension educators and growers."
