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.

    Entries judged by a panel of five pecan scientists represented pecans grown in the previous season (2011), and were lower in number (199) due to the drought conditions experienced throughout Texas last year.
    • The Grand Champion Commercial Pecan was grown by Pat Baggett, Cinco B Farms, Washington County, Pawnee variety, 38 per pound, 61.07% kernel
    • The Grand Champion Classic or New Pecan Variety was grown by Ed & Dorothy Fisher, Midland County, Waco Variety, 43 per pound, 57% kernel

  • New in the Toolbox!
    The Pecan Budget Tool provides an interactive budget for a single year's pecan production. The tool is an easy-to-use downloadable Microsoft Excel spreadsheet that calculates operating costs and profit by collecting specific information about a current or potential pecan producer operation including:
    1. Fixed cost information - your loans, maintenance costs.
    2. Variable (running costs) - e.g.,fuel costs, irrigation, pesticide and fertilizer applications, and harvesting and cleaning costs.

  • July is Leaf Nutrition Month
    It's that time of year again. July is the time to collect and submit leaf samples for analysis to determine the amount of essential minerals your pecan trees are absorbing from the soil or from foliar treatments. Nitrogen, potassium, zinc and other nutrient deficiencies can be identified from leaf samples. We have developed an information packet with instructions and locations for submitting leaf samples. Instructions for Pecan Leaf Sample Collection for Nutritional Analysis
  • Walnut Sphinx Pest Alert
    In early July 2012, an outbreak of the walnut sphinx, Amorpha juglandis, was infesting and defoliating about 100 acres of primarily native orchards between Highway 36 and 1702, south of Gustine, Texas.
