Across the 12-county Southern Rolling ...

Across the 12-county Southern Rolling Plains region, about 60 percent of the irrigated cotton and more than 75 percent of dryland has been harvested to date, and except for a few stragglers, the harvest should be done by Christmas, said David Drake, an agronomist at San Angelo's Texas A&M AgriLife Research and Extension Center.

"We have a range of everything this year," Drake said. "We have the risky West Texas cotton fields that were 'droughted' out and hailed out. And we had some on the other end of the spectrum that just happened to get a timely rain in the right spot and were above average." Cotton yields in the West Central, Far West and Rolling Plains region were basically a little below average, and behind in maturity and harvest, he said. "The crop was much later in terms of when we got the rain and when it produced the fiber," Drake said. "A lot of areas still haven't been harvested. Typically this year we'd have all our variety trials in. This year we've still got five or six trials to go, and there are a lot of producers in the same situation." Growers had a tough year with defoliation. Late rains caused the cotton plants that had already been treated to regenerate. "Cotton is a perennial crop, so it started growing again, and that really made it tough to knock the leaves off," Drake said. "The freeze helped, but coming when it did, it hurt the crop in terms of quality, and the leaves stick on and get mixed in with the fiber, resulting in too high leaf scores." Freeze also increases bark contamination, he said. "Bark" refers to parts of stem, which are hard to gin out and result in dockage. Drake also noted that some southern counties of Rolling Plains did not have such a good year. "It's all dryland, but in a good year they can get really good yields, 2 bales per acre," he said.
Wheat Disease Threatens Crop | Texas Wheat

"Recent rains in the Southern Rolling Plains and throughout West Central Texas have increased the prospects of getting an average or even an above average wheat crop this season," said Dr. David Drake, AgriLife Extension agronomist at San Angelo.

Drake said the only known way to combat leaf rust is to plant resistant varieties or apply a preventative fungicide. Since the crop is fast approaching maturity, applying fungicide is now the lone alternative.
"Growers need to scout their fields every few days by walking out into the crop and looking closely at the plants," Drake said. "Leaf rust begins as small yellow spots on the leaves. Advanced infestations will have larger spots covered with powdery rust-colored spores which give the disease its name."
Drake said the spores are spread by wind or water and soon infect other leaves and plants.
Stripe rust, another fungal disease, is similar in appearance to leaf rust but develops stripes across the leaf instead of spots. Cool temperatures contribute to stripe rust and so far, he said it's not been found this year.
"If producers do find rust in wheat, then they need to evaluate the condition and growth stage of the crop, its potential yield, the grain price and the cost of the treatment before proceeding," Drake said.
...
Research has shown that the flag leaf, the leaf just below the head, can contribute up to 85 percent of the grain, Drake said. He said the best time to spray is when the flag leaf is emerging on up to the time of its full emergence. Later spray applications are not as effective.
"Most of the wheat in our area is very rapidly approaching this stage," he said.
