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.
- The March 2013 issue of Bill Ree's Texas Pecan Pest Newsletter is online.
The Pecan Nut Casebearer (PNC) Data Collection program used to generate the public PNC Risk Map
will operate again in 2013. New cooperators can join by visiting the PNC Cooperator Programs section
of the website, registering with the system (if they haven’t already done so), and clicking on the “Become a Cooperator” link on the menu bar. Educational materials for PNC are also available on the website.Â
- Dr. George McEachern, Professor of Horticulture at TAMU, has prepared a calendar to aid pecan producers in conducting pecan management activities throughout the year.
- The Texas State Pecan Show, the largest and longest running pecan show in the U.S., was held July 15, 2012 in conjunction with the Texas Pecan Growers Association annual conference in San Marcos, Texas.
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
- The Grand Champion Native Pecan was grown by K&K Pecans, Menard County, 72 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:
- Fixed cost information - your loans, maintenance costs.
- Variable (running costs) - e.g.,fuel costs, irrigation, pesticide and fertilizer applications, and harvesting and cleaning costs.
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.

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.

- Texas Pecan Pest Management Newsletter - June 2012
- The Pecan ipmPIPE Library now provides links to two classic bulletins by Dr. S. W. Bilsing; Dr. Bilsing was a Professor of Entomology at TAMU who conducted and published the first meticulous study of the pecan nut casebearer, Acrobasis nuxvorella Nuenzig. This work has been instrumental in crafting the management programs for this key pecan pest. Now you can read this work in the original. Go to the Library and search by author Bilsing.
- The Pecan Scab Risk Assessment Tool is live online just in time for the start of Pecan Scab Season!
- With the start of a new season just around the corner this is a good time for some sprayer maintenance and calibration. Read this and other important tips from Bill Ree in the latest issue of Texas Pecan Pest Management Newsletter available here.
January - February 2012
- The Pecan Nut Casebearer Data Collection Program has moved online! Pecan stakeholders who have agreed or wish to participate can register or login here (or by choosing Cooperator Programs > PNC Data Collection from the left menu bar). This innovative program will provide real time PNC data entry from the field to drive a PNC Risk Assessment Model that will appear in a belt-wide map to aid producers in making PNC management decisions in the 2012 season.

- Walnut Caterpillar Alert
- May 15 -- Producers should be on the lookout for walnut caterpillars starting to lay eggs in the next generation in about 3 weeks and then expect one more generations to occur about 6 weeks after that. Walnut caterpillars have been found as 4th instar larvae and are occurring earlier than usual in Victoria (Victoria County) and Cuero (DeWitt County), Texas. Photo credit: Howard Arnett
- Pecan Weevil Alert
Pecan weevil management decision-making is upon us. Note that many pecan growing areas are facing drought conditions. This may result in drought-delayed emergence well beyond the normal emergence time for this pest, particularly in orchards and groves with clay soils.

- Thousand Cankers Disease of Black Walnut
This disease reported found in Tennessee July 26, 2010. (See companion materials listed below for details.) Based on limited research, pecan is not known to be at risk from this disease. Scientists at Colorado State University will provide expert assistance if this disease is suspected present and local scientists should also be informed.
