Resistant Pigweed Possibly Found
in High Plains Fields
Friday, September 9, 2011 By Mary Jane Buerkle
Dr. Wayne Keeling with Texas AgriLife Research said that their staff first was made aware of potential problems around the first of August, when experts reported a couple of fields in Terry County where Palmer amaranth, more commonly known as pigweed or carelessweed, had survived multiple glyphosate applications, possibly exhibiting resistance.
Dr. Peter Dotray, also with Texas AgriLife Research and the Department of Plant and Soil Science at Texas Tech, said he has received phone calls reporting possible resistance in the past, but other issues such as herbicide rate, carrier volume, spray coverage, weed size, and overall environmental conditions were noted as the likely cause.
Texas AgriLife Research staff collected soil samples from the areas where actively growing weeds were present and cultivated pigweed in their greenhouse. They then made glyphosate applications over a wide rate range. The weeds survived glyphosate rates equal or higher than normal use rates.
"Preliminary greenhouse results indicated that glyphosate-resistant weeds were present in these fields," Keeling said, adding that additional soil and weed seed samples have been collected for further study.
Dotray and Keeling noted that this is disturbing news for area producers, and reiterates the need to implement aggressive weed resistance management strategies, including the use of pre-plant incorporated pre-emergence and post-emergence herbicides with residual weed activity.
Keeling said producers should be proactive and closely monitor fields, destroying suspicious weeds as soon as possible.
"Get rid of what you can," Keeling said. "That will limit the production of additional resistant seed and help prevent the problem from becoming more widespread next year."
Producers who repeatedly have sprayed fields with glyphosate this season and have surviving weeds should contact Keeling or Dotray at the Texas AgriLife Research Center, (806) 746-6101. Plains Cotton Growers also will keep you updated with additional information.
Plains Cotton Growers, Inc. is teaming up with Under Armour and Texas Tech for the Under Armour Cotton Game on Saturday, Oct. 8, as the Texas Tech Red Raiders host the Texas A&M Aggies at Jones AT&T Stadium.
Cotton will take center stage throughout the week and during the game. A cotton industry representative will be a part of the coin toss, and Under Armour will host a special Cotton Tailgate. The Texas Tech coaching staff will be outfitted in "Charged Cotton" apparel. The Under Armour tractor-trailer will set up on the Lubbock campus in the days leading up to the game to engage students and the community in activities and to showcase Under Armour's "Charged Cotton" line of t-shirts, shorts, pants and sweatshirts.
"This definitely is a win-win for the High Plains cotton industry," PCG's Executive Vice President Steve Verett said. "Cotton once was the enemy to Under Armour, but we are thrilled that they have now embraced it and made it a part of their popular clothing line as "Charged Cotton". We're proud to be a part of this event and look forward to celebrating one of the pillars of our area economy."
It's a win for those interested in attending the game, too. Texas Tech Athletics is offering tickets to the Texas A&M game at a significant discount from regular-priced tickets.

Textile executives from 14 countries throughout the world will visit the U.S. Cotton Belt Sept. 12-22 to familiarize themselves with U.S. cotton and how the fiber is produced, processed and marketed. The bi-annual COTTON USA Orientation Tour is sponsored by Cotton Council International.
CCI President John Mitchell, a Cordova, Tenn., merchant, said, "The Orientation Tour is vital to U.S. cotton export performance. For years, this event has enabled our industry to showcase our high quality fiber to important international spinners as well as build and strengthen relationships with these customers."
The 31 participants represent 28 companies in Bangladesh, China, Colombia, Ecuador, India, Indonesia, Japan, Korea, Pakistan, Peru, Taiwan, Thailand, Turkey and Vietnam. These companies are expected to consume about 3.6 million bales in 2011, 1.3 million of which are estimated to be U.S. cotton Ð about 11 percent of U.S. cotton exports.
The participating countries are expected to consume about 96 million bales of cotton in 2011-12. This represents about 83 percent of the total annual world cotton consumption. This Tour's countries also purchased 12.3 million bales in 2010-11, which accounts for 90.25 percent of U.S. cotton exports.
Tour participants will visit a farm and gin in the Mid-South; observe cotton research in North Carolina, Mississippi and Texas; and tour the USDA cotton classing office in Bartlett, Tenn. They will meet with exporters in the four major Cotton Belt regions and get briefings from CCI, the National Cotton Council, Cotton Incorporated, the American Cotton Shippers Association, the Texas Cotton Association, the Lubbock Cotton Exchange, AMCOT, the Western Cotton Shippers Association, the American Cotton Producers, the Southern Cotton Growers Association, the Delta Council, Plains Cotton Growers Inc., Texas Cotton Producers, the San Joaquin Valley Quality Cotton Growers Association and Supima.
More than 800 textile executives from more than 60 countries have toured the U.S. Cotton Belt via CCI's Orientation Tour, which was initiated in 1968. The Tour's objectives are to increase U.S. cotton customers' awareness of the types/qualities of U.S. cotton, help them gain a better understanding of U.S. marketing practices and enhance their relationships with U.S. exporters. The Tour has led many foreign textile manufacturers to develop an appreciation for U.S. cotton fiber quality and furthered the U.S. cotton industry's reputation as a reliable supplier. The tour continues to be an excellent vehicle for helping U.S. cotton capture additional market share overseas.
The All-Tex field day will be Wednesday, September 14, from 10 a.m. to 2 p.m. at Levelland Delinting, located at 2200 West Avenue in Levelland. Lunch from River Smith's will be served from 11:30 a.m. to 1 p.m. Participants can earn CEUs, win door prizes, and go on crop tours.

High Plains Water District Releases
Approved Flow Meters List
The High Plains Underground Water Conservation District No. 1 has released a list of flow meters approved for use in measuring water production of individual wells or well systems within the district's 16-county service area.
The list, along with a meter specification manual, is now available for viewing/downloading at http://www.hpwd.com. Printed copies also are available at the High Plains Water District office, 2930 Avenue Q, in Lubbock or by calling (806) 762- 0181.
The meter manual contains four sections: water meter manufacturer specifications; water meter installation, inspection, and sealing specifications; a list of approved alternate measuring methods; and the approved meter list.
In addition, there is an appendix containing relevant provisions from Rule 5 of the High Plains Water District Rules regarding metering.
The water well metering requirement and reporting of annual water use within the district for all non-exempt wells and certain exempt wells was included in rules amendments adopted by the High Plains Water District Board of Directors on July 19.
These amendments are designed to implement the district's "50/50" management goal of having 50 percent of the saturated thickness of the Ogallala Aquifer in 2010 available for use in 2060.
Created in 1951 by local residents and the State Legislature, the High Plains Underground Water Conservation District No. 1 is charged with the responsibility of conserving, preserving, protecting, and preventing waste of groundwater within its 16- county service area.
