College Station, TX — The Texas A&M AgriLife Extension Service and the Texas Plant Protection Association have collaborated on a Flag the Technology program that identifies crop fields sensitive to certain herbicides.

With two new herbicide resistance technologies which will be widely used in cotton, corn and soybeans, program coordinators say it is critical farmers know which fields are safe for application of the new products and which are sensitive to them.

The program, which originated in Arkansas, is a system that helps farmers identify fields that are safe for application and those which must be avoided to prevent unintentional damage to the producers field or to adjacent crops. Farmers will place colored flags at entry points on fields, with each flag color representing a different kind of technology. This will make  herbicide applicators aware which products are appropriate and safe to use on a specific field.

“Farmers throughout Texas will be learning more about this program throughout 2017,” said Dr. Travis Miller, AgriLife Extension interim associate director for state operations in College Station. “We will also distribute a publication that will help explain the flags used in the system and AgriLife Extension faculty will be discussing flag technology in producer meetings.”

Texas Plant Protection Association chairman Ray Smith in College Station said during the association’s recent conference in Bryan the program and mobile app will “help enlighten our farmers on how to use the new technology. This app also emphasizes good recordkeeping.”

The mobile app can also be available to spray applicators who can check flag colors as they enter a field. The flag indicates which products they can use.

FLAGS

The following are flag colors and uses:

White — Technology is tolerant to glyphosate herbicides.

Green — Tolerant to glufosinate herbicide, Liberty.

Yellow — Clearfield rice, sunflowers, wheat and canola which are tolerant to imidazolinone herbicides.

Teal — Tolerant to both 2, 4-D and FOP (ACCase) herbicides, or Enlist technology. The white stripes indicate tolerance to glyphosate, Roundup. For Enlist cotton traits and soybean fields, a green flag should be added to denote tolerance to glufosinate herbicide (Liberty).

Black and white checkered —Tolerant to both dicamba, Engina and Extendimax, and glyphosate, Roundup Ready Xtend.

Red — Extreme caution required. Indicates conventional crops with no herbicide tolerant traits as well as sensitive production areas such as vegetables, vineyards, apiaries and organic production.

The new app builds on the field program developed by Bob Scott at the University of Arkansas, Smith said. Dr. Todd Sink, AgriLife Extension wildlife and fisheries specialist in College Station, developed the Flag the Technology app.

Users also have the option of meshing the app with Hit the Target, formerly known as Texas Crop Registry, a voluntary program that allows producers with sensitive crop areas to register specific fields, including non-GMO acres, orchards and others, said Dr. Bob Coulson, Texas A&M AgriLife Research entomologist.

“That information will be available to pesticide applicators,” Coulson said. “Individuals must register to use the system. Producers who register will specify field location and add the crop or sensitive nature of the area.”

Coulson said producers would need to calculate field dimensions. With that information logged in, Coulson said, the producer can go to the Flag the Technology program and select the color flag needed for the fields.

“The applicator will have a dashboard with the field profiles included to prevent off-target applications,” Coulson said. He added Hit the Target will soon transition to a new program, which can be accessed through a mobile device.

Sink said the Flag the Technology app is user friendly.

“It loads within five seconds,” he said. “The pesticide applicator is aware of where sensitive crops are located and can adjust flight plans to avoid those areas.”

The mobile app will be available free for iTunes and Google Play. A publication about the program is available for download at http://bit.ly/2j9Sce0 .
