Pest Information Platform for Extension and Education
Welcome to Pecan ipmPIPE
The mission of the Beltwide Pecan ipmPIPE Program is regional participation in a dynamic, integrated national system that provides useful, reliable information and tools for IPM practitioners throughout the "pecan belt," the principal states where at least some commercial pecans are grown. Our vision is to develop the ipmPIPE to help maximize economic returns, and improve social welfare and environmental health by promotion of efficient and coordinated IPM decision support systems. Read more about the national system's background and mission.
Pecan Scab Season Is Here...
And so is the Pecan Scab Risk Assessment Tool. We developed and tested the tool last summer (too late for the start of the season), so some of you might not be aware that it's live this year and ready to assist you with pecan scab management decisions. Check it out.
As always, the tools on the Pecan ipmPIPE site were developed for you, our cooperators, so we depend heavily on your feedback. Let us know what you think of the Pecan Scab Tool.
