by Jason Woodward, Associate Professor and Extension Plant Pathologist, Texas A&M AgriLife Extension, Lubbock, TX; 806.746.6101; jewoodward@ag.tamu.edu In addition to fungicide seed treatments, there are several nematicide seed treatments available for producers to use in the management of root-knot (Meloidogyne incognita) and reniform (Rotylenchulus reniformis) nematodes. Abamectin, the active ingredient in Acceleron-N and Avicta Complete Cotton (offerings on Deltapine and Phytogen varieties, respectively), has been registered for use in cotton for approximately 10 years. Acceleron-N and Avicta Complete Cotton differ from earlier products, namely Avicta Duo, in that… Read More →

By Ronnie Schnell  (ronschnell@tamu.edu) and Gaylon Morgan (gdmorgan@tamu.edu) Texas A&M AgriLife Extension, College Station Low commodity prices often results in a shift in acreage from one crop to another. However, when crop prices are low across the board, growers must look for alternative ways to remain profitable. Crop inputs are naturally the first place many will look. Will reducing input costs increase net returns? The wrong cuts could result in yield reductions and/or detrimental impacts over the next several years, such as with poor weed management. Increasing efficiency may… Read More →

by Thomas Isakeit, Professor and Extension Plant Pathologist Following a very wet and slow start in 2015 and some seedling disease issues, there is more interest in seed treatments to minimize seedling losses and get the crop off to a good start. On the other hand, farmers are looking for ways to cut input cost and are curious about the value of the seed treatments. To address some of these questions, I have updated a listing of fungicides labeled for seedling diseases of cotton, which can be found… Read More →

by Dr. Clark Neely, Small Grains/Oilseeds Extension Specialist – College Station, TX; Dr. Ron French, Grain and Vegetable Extension Plant pathologist – Amarillo, TX It is now February and we are once again seeing significant rust levels in wheat in areas of Southern and Southeast Texas. The elevated levels of rust this early in the season is eerily similar to 2015; however, leaf rust appears to be more prevalent at this time than stripe rust, unlike 2015. Currently, wheat planted prior to December 1 seems to be most… Read More →

Several factors may contribute to current wheat conditions, including how well wheat was established. However, remember first that wheat and other grasses like rye and triticale are cool-season grasses. Popular wheat varieties planted in the Texas High Plains like Winterhawk, Hatcher, and TAMs 111, 112, & 113 are… Read More →

by Dr. Calvin Trostle, Extension Agronomy, Lubbock, (806) 746-6101, ctrostle@ag.tamu.edu In 2016 Texas grain sorghum producers will find more information from seed companies and other sources about grain sorghum hybrids that may offer potentially increased—or better documented—tolerance/resistance to sugarcane aphid (SCA). I provide a link to a list of recent seed company designated SCA-tolerant/resistant hybrids below, but I recommend caution in evaluating information regarding sugarcane aphid tolerance/resistance. Access the full document for additional considerations. Foremost, at this time: 1) Assume all grain sorghum hybrids—even if designated tolerant/resistant to… Read More →

by Dr. Clark Neely, Statewide Small Grains Extension Specialist, Texas A&M AgriLife Extension Retaining Volunteer Wheat A unique situation is unfolding for many wheat producers across the state of Texas this fall, particularly for areas of the Blacklands, which started back in the spring. Torrential spring rains destroyed or otherwise prevented harvest of many wheat acres throughout Texas in 2015 providing a large seedbank of wheat seed in the soil. Once fields were abandoned or insured out, drought quickly set in for much of the summer months, allowing… Read More →

by Emi Kimura, Assistant Prof., Vernon; emi.kimura@tamu.edu and Clark Neely, Assistant Prof., College Station; cneely@tamu.edu Winter wheat in the 2014-15 crop year endured a wet spring, which caused pre-harvest sprouting and many head diseases (stinking smut, loose smut, and Fusarium head blight or scab infection) throughout the regions in the state. Some areas of the state had less than 30% germination on wheat acres planted for forage due to the low quality wheat seed. The wet conditions in the spring of 2015 lowered the quality of wheat seed… Read More →

by Thomas Isakeit, Professor and Extension Plant Pathologist, College Station Goss’s wilt is a bacterial disease of corn, caused by Clavibacter michiganensis subsp. nebraskensis, which had been restricted for decades to Colorado and a few Midwestern states since its first discovery in 1969. In recent years, it appeared beyond this area, mostly in more Midwestern states, but additionally, in 2013, to the north and west, in Alberta and to the south, in Louisiana – a separation of 1900 miles and in growing areas each with very different climates… Read More →
