Did recent rains come too late for the South Texas cotton crop?

by Josh McGinty and Gaylon Morgan, Texas A&M AgriLife Extension Service The 2018 season in South Texas has been a tough one. In southernmost areas, a dry winter and spring meant planting moisture was scarce, while excessive rainfall was a common problem that delayed field preparation and planting in the Upper Gulf Coast. Since planting, excessive heat, wind, and very limited rainfall has been a common occurrence across South Texas, leading to severe moisture stress and early cutout (5 nodes above white flower) in many fields. Then on… Read More →

Blacklands and River Bottom Insect Pest Update – June 14

by Dr. David L. Kerns, Professor and IPM Coordinator Crops have been suffering from intense heat and lack of moisture over the past 2 weeks but we are hoping for some relief over the next 3 to 4 days.  The high temperatures and lack of moisture have contributed significantly to some severe pest problems, namely cotton fleahoppers and spider mites.  As vegetation in the landscape dries up, these pests are forced to seek other food sources and have moved into cotton throughout much of the Blacklands and the… Read More →

Corn Growth Stages and Post Emergent Herbicide Timing

by Jourdan Bell, Texas A&M AgriLife Assistant Professor and Agronomist – Amarillo Post emergent herbicide applications are necessary for season long weed control. Post emergent corn herbicide labels define the latest growth stage for which herbicide applications can be made without causing crop injury. Herbicide applications past the recommended application stages can result in significant crop injury. For some herbicides, later applications can be made according to the label, but drop nozzles are recommended to prevent herbicides being sprayed in the whorl. Some herbicide labels provide a recommended… Read More →

Update on Off-Target Movement and How to Minimize the Risk of Enlist Herbicides Moving Off-Target

by Gaylon Morgan, Pete Dotray, and Scott Nolte Numerous complaints have been received from the off-target movement of auxin herbicides in parts of South and East Texas over the past two weeks.  Due to the extremely high sensitivity of cotton to 2,4-D, it is not too surprising that most of the incidents appear to be off-target movement of 2,4-D.  In much of Texas, observing 2,4-D injury in cotton is common, but some of the incidents this year do appear to be from applications in row crops.  We do… Read More →

2018 Canola Field Days

by Dr. Clark Neely, Small Grains and Oilseeds Extension Specialist Canola is a relatively new alternative cool-season crop option for growers across Texas. With wheat prices low and canola prices hovering around $7.75/bu, some growers may find it to be a more economical option. Agronomic and variety trials have been conducted by numerous Texas A&M AgriLife Research and Extension scientists over the past decade across the state. Currently, canola trials are conducted at the Texas A&M AgriLife Research and Extension Centers in Bushland, College Station, Corpus Christi, and… Read More →

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 →
