Test Your Knowledge of Integrated Weed Management
by Muthukumar Bagavathiannan, Scott Nolte, Peter Dotray, Joshua McGinty, Gaylon Morgan Effective and sustainable long-term weed management requires integrating diverse techniques, as opposed to relying solely on one or two tactics. This is particularly true as troublesome herbicide-resistant weeds continue to develop and spread throughout Texas and the U.S.A. Diversifying weed management inputs reduce the risk of herbicide-resistant weeds developing and spreading. This brief, 20-question quiz will help you test your understanding of Integrated Weed Management (IWM) and help us recognize where IWM research and outreach efforts should… Read More →
Physiological Leaf Spotting in Wheat
by Dr. Clark Neely, Statewide Small Grains Extension Specialist, Texas A&M AgriLife Extension; Dr. Jake Mowrer, Statewide Soil Fertility Extension Specialist, Texas A&M AgriLife Extension Without fail, every spring there are questions about yellowing or flecking in wheat across Texas, particularly in Central and South Texas. The first thing that comes to mind is rust. In many cases that is true; however, there have been several instances where rust was not an obvious culprit. Other candidates that come to mind were fungal pathogens such as septoria, tan spot,… Read More →
The Trap of Beardless Wheat & Forage Quality
by Dr. Calvin Trostle, Professor & Extension Agronomist, TAMU Dept. of Soil & Crop Sciences, Lubbock, 806-746-6101, ctrostle@ag.tamu.edu; Discussion of forage quality it is fairly common, and the emphasis placed on forage quality among forage growers and livestock feeders ranges from none to strong consideration. Texas A&M AgriLife (Trostle) discusses examples of forage quality as well as tips for producing, selling, buying, and storing different forages in a new PowerPoint that examines these issues from several viewpoints. There are a number of considerations participants in the forage production,… Read More →

Does an Early Fungicide Application Pay in Wheat?
by Dr. Clark Neely, Statewide Small Grains Extension Specialist, Texas A&M AgriLife Extension Dr. Tom Isakeit, Extension Field Crops Pathologist, Texas A&M AgriLife Extension Despite the wet, dreary weather some parts of the state have experienced over the past few weeks, rust levels appear to be low at this time for most of the wheat acres in the state. However, I still receive questions on whether a topdress or pre-flag leaf application of fungicide is a good idea. In most cases, the answer is “no”, an early fungicide… Read More →

We have observed dramatic results of hybrid… Read More →
Application Timing is Critical With Auxin Herbicides
by Josh McGinty – Extension Agronomist, Corpus Christi, TX; Scott Nolte – State Extension Weed Specialist, College Station, TX; Peter Dotray – Extension Weed Specialist, Lubbock, TX; Muthu Bagavathiannan – Research Weed Scientist, College Station, TX; Gaylon Morgan – State Extension Cotton Specialist, College Station, TX With the introduction of new formulations of 2,4-D (Enlist One and Enlist Duo) and dicamba (XtendiMax, Engenia, and FeXapan) for use in Enlist and XtendFlex cotton, growers now have more options for controlling emerged broadleaf weeds, especially those that may be resistant… Read More →
Texas Wheat Disease Update
by Dr. Clark Neely, Statewide Small Grains Extension Specialist, Texas A&M AgriLife Extension Dr. Emi Kimura, Regional Extension Agronomist, Texas A&M AgriLife Extension Dr. Tom Isakeit, Extension Field Crops Pathologist, Texas A&M AgriLife Extension For wheat growers in a good chunk of the state, we are finally getting some beneficial rain (unfortunately this does not include the Panhandle). This is good news with more and more of the state slipping into exceptionally dry or drought conditions this winter. However, with spring rains sometimes comes rust pressure in wheat… Read More →
“Nitrogen and Texas Wheat Grain Production—Topdress N Timing is Critical”
by Dr. Calvin Trostle, Extension Agronomy, TAMU Dept. of Soil & Crop Sciences, Lubbock, 806-746-6101, ctrostle@ag.tamu.edu; Dr. Jake Mowrer, Extension Soil Fertility, TAMU Dept. of Soil & Crop Sciences, College Station, 979-845.5366, jake.mowrer@tamu.edu Soil & Crop Sciences extension has developed a new publication for Texas wheat. Nitrogen topdress timing involves recognizing the key jointing growth stage in wheat, and understanding when conditions may merit earlier application of topdress N. Much of the discussion in the new document is presented in the context of twelve common grower questions about… Read More →
2017 Texas A&M AgriLife Bushland Forage Sorghum Silage Trial
by Jourdan Bell, Jourdan.bell@ag.tamu.edu Ed Bynum, EBynum@ag.tamu.edu Ted McCollum, Ted.McCollum@ag.tamu.edu Ronnie Schnell, ronschnell@tamu.edu The 2017 Texas A&M AgriLife Bushland forage sorghum silage trial consisted of 78 entries including forage sorghum, sorghum-sudangrass, sudangrass, and grain sorghum hybrids under center pivot irrigation. Two corn hybrids were included for comparative purposes. Due to declining well capacities across the Texas High Plains, forage sorghums are a drought tolerant option to meet the increasing silage demands of both the beef feedlot and dairy industries. The large scale of the Bushland trial provides producers… Read More →
