Randy Norton, University of Arizona Extension Cotton Specialist, Safford:
“I was out last week so it was nice to get home and see the crop looking better, but we’re still behind. Fortunately, heat stress hasn’t been too bad. We’ve had very few Level 2 heat stress days, which occurs when the leaf canopy temperature surpasses 86 degrees. Pollination is disturbed and bolls are lost. Last year we had quite a few heat stress days, so we’re thankful.
“We are seeing issues with aphids in southeast Arizona. There is still lygus pressure statewide but very little whitefly.
“Pigweed resistance is showing up again. I had two calls from growers about pigweed that is not dying after 3 sprays with Roundup. We’re seeing this more and more.
“Growers are looking for different weed control options. My message to them is: if you have pigweed out of control, get it out of the field and don't let it go to seed. Use a hoe if necessary because if it goes to see, you'll have bigger problems next year."
Murilo Maeda, Texas A&M AgriLife Extension Cotton Specialist, Lubbock:
“Most of our fields are well into squaring. There are late planted fields around Lubbock, so growth is variable. There will definitely be issues with late cotton maturity.
“Many areas received good moisture early last week. A major hail storm on July 10, near Tulia, caused major damage on 4,000 to 6,000 acres. Another storm hailed out a few field trials at the research station as well.
“Everything else looks good. There are still fleahoppers around. Guys need to stay on top of them to promote good early fruit retention. That will be critical if we end up having a short season.
“A few areas are getting a little dry. Lynn, Dawson and Terry counties need a rain.
“Herbicide applications are catching up after the slow start so weed control is better. I want to remind folks to be extra careful with their auxin herbicide applications. Follow the label. We must prevent any off-target movement.”
Jerry Stuckey, farmer and general manager, Northwest Cotton Growers Co-op, Inc., Moscow, Kansas:
“Cotton finally took off. Mine was planted May 30 when it was still wet. Most of it has at least 3 nice squares. The cotton has really grown in the past week. We’ve been in the 100s and it’s forecast to stay there the remainder of this week, but back to the 80s next week.
“I expect the first blooms about August 1. There are a few early fields that survived the bad spring, which should be blooming before then. Most good stands are in the late stuff.”
Orlando Flores, Texas A&M AgriLife Extension Agent, El Paso County:
“We’ve had 100-degree weather and the crop loves it, especially the Pima. This is ideal El Paso Valley cotton weather. Everything really looks good. Pima cotton has the yellow flowers. It’s a beautiful plant. The sad thing is that we didn't plant much cotton because we didn't have a large enough allotment of irrigation water.

“There are precautionary treatments going out for lygus and bollworms. Also, we continue to monitor FOV4 fusarium wilt research plots. This is a joint effort between AgriLife Extension and Research, New Mexico State University, USDA-ARS and Cotton Inc. We’re determined to keep this disease under control.”
