The brown marmorated stinkbug is moving west. A national program at Rutgers New Jersey Agricultural Experiment Station is involved in identifying and reporting new discoveries of this invasive pest. Reports may be made directly to the website link, although we recommend working with your local experts first to confirm the pest is present. Bill Ree is a local expert who can be contacted regarding this pest on pecan in Texas.

  • Protect your orchard from offsite pesticide drift by using the Texas Crop Registry. Pesticides are an important tool for agriculture, but pesticides applied to one crop have the potential to drift and cause damage to surrounding crops. For example, a pecan orchard located next to a field crop may be at risk from broad-spectrum herbicides used for early season weed control. In recent years the risk from pesticide drift has increased with the widespread use of herbicide tolerant crops.
    The Texas Crop Registry is designed to protect growers and pesticide applicators in Texas by maintaining maps of crop locations at risk to pesticide drift. Pesticide applicators can use these maps to assess whether any precautions should be taken to reduce drift. The registry is free and easy to use: simply register with the site then enter the location of your pecan orchard(s) or any other at risk crops.
  • The time to put out pecan nut casebearer pheromone traps is rapidly approaching, or even here for our most southerly producers in the pecan belt. The list of suppliers is provided for your use and we also would like you to join our PNC Cooperator Program to aid the industry in risk assessement for this important pest.

  • El Paso County Agrilife Extension Center IPM Newsletter is now available in the library.
  • The Pecan Scab Risk Assessment Map tool will not be operational in 2014 due to a lack of funds to maintain the integrity of the real-time data input/output processing required to continue to provide this service. Previous histories for 2011-2013 provide a ”proof of concept” and can be made available for reference purposes. The tool can be reinstated if/when resources can be found to update and maintain it.

The Pecan Scab Risk Assessment tool is currently dysfunctional. Our initial diagnosis indicates this is a data flow problem involving NOAA data, the pecan scab risk analysis model we have developed and how the massive databases being created are updated, archived and retrieved. The solution requires purchasing Information Technology expertise and an upgrade of hardware and software to bring the tool back online.
The grant funding this program ended a year ago and new funds and funding streams are being sought to maintain the website. We intend to get this management aid back online ASAP and regret this break in service. We note that even though this website was designed to operate with minimal maintenance needs, some resources will always need to be provided by someone to maintain this website.

The Texas State Pecan Show was held July 15, 2012, in conjunction with the Texas Pecan Growers Association annual conference in San Marcos, Texas. This show represents the 61st consecutive year that a competition recognizing the top quality pecans in the state has been held. The Texas Pecan Show is the largest and longest running pecan show in the U.S. 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

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.

March - April 2012

  • Pecan scab season has started. The Pecan Scab Risk Assessment Tool is now live and ready to help you make pecan scab management decisions.
  • The latest issue of Texas Pecan Pest Management Newsletter is hot off the press and waiting for you in the Library. Search by author “Ree, W” (without the quotation marks).

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.

  • Pecan Scab Risk Assessment Aid to Disease Management–Browser Alert
    Some pecan stakeholders using Internet Explorer report difficulty loading this screen. If you are using Windows 7, please upgrade to Internet Explorer 9. No incidents reported with other browsers.
  • Annual meetings of producer organizations provide an excellent opportunity for growers, scientists and others interested in the nut industry to share ideas and experiences. These and other producer organizations helped found and continue to support the Pecan ipmPIPE program.
  • 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.View/Download Instructions for Pecan Leaf Sample Collection for Nutritional Analysis

  • Pecan Scab Risk Assessment Aid to Disease Management
    The new Pecan Scab Risk Assessment tool is now available. The tool provides a beltwide risk overview for the past 7 days, with links and instructions for customizing the assessment for your location. Please note that extensive help functions and background materials are provided. These will help you navigate through various features and get maximum value from this program deliverable. Reading them will reward you in learning how to use the system best for your purposes. Damon Smith, Pecan Plant Pathologist at Oklahoma State University, provided the leadership to make this tool available to the pecan industry. Please let us know what you think.
  • Try the new Herbicide Search Engine
    Weeds can present problems in pecan orchards because they compete with pecan trees for water, light, and nutrients. Therefore, weed control should be an important part of the overall pecan orchard management plan.To better serve our stakeholders, the Pecan ipmPIPE team has developed an herbicides search engine. The database behind the search engine was developed by Dr. Jamshid Ashigh, Extension Weed Specialist and Herbicide Specialist at New Mexico State University. The content of the database is based on Dr. Ashigh’s publication, Integrated Weed Management in Pecan Orchards. View/download the publication in the Library. Search on author name “Ashigh” (without the quotation marks).

PNC looks early this year in southern Texas
Pecan IPM pays off by conserving yields and sustaining annual production to help producers meet demands from a growing export market. The 2011 pecan nut casebearer (PNC) moth flight has gotten underway early in 2011 (see PNC Risk Map under Maps). Management of this pest is key to start the season and other information on this site is useful in ensuring the best crop possible is obtained. For information on the growing export market see the April 18 article in The Wall Street Journal.
