Here is this week's issue of AgFax Southwest Cotton, sponsored by PhytoGen.
Breaking News 8/12: "Cotton futures surged as much as the daily limit on heavy volume Wednesday, spurred by sharply lower U.S. crop prospects and smaller domestic and world ending stocks reported in USDA supply-demand estimates."

Insect traffic report: Verde plant bugs, brown stink bugs, leaf-footed bugs remain in the picture on coastal areas. Lygus are threatening to invade fields in parts of the South Plains. Tarnished plant bugs and stink bugs are also apparent in southern Kansas. Sugarcane aphids have stretched into sorghum fields in the northern Panhandle and beyond, and have caused some Blacklands harvest headaches.
Resistant Weeds and just plain ole' weeds keep coming. Hoe hands and residuals are worn out.
Multiple crop stages in individual fields continue to be a "nightmare" for PGR applications.
Randy Boman, Oklahoma State University Cotton Research Director, Cotton Extension Program Leader, Altus: "There is some 2-bale dryland out there. A lot of dryland looks good even though the cotton is getting pretty thirsty. We're still irrigating full tilt. If we can get a general rain it will help a lot.
"The majority of the crop is at 6 to 8 NAWF and ranging from good to excellent. However, we're beginning to see a little heat stress. It's to be expected after 3 weeks of 100-degree temperatures. A few showers here and there have cooled it off a little. But we've been evaporating a lot of water, with the heat index at 105 to 110 degrees. Crop ET has been at about 0.3 of an inch.
"There are no major insect issues, other than a few aphids reported around Altus. We're thinking that beneficial insects will take them out."
Jim Johnson, Independent Crop Consultant, Corpus Christi, Texas/Coastal Bend: "We started defoliating earlier fields today (8/11). It's a nightmare because there is a lot of variability. Some parts of fields will top 2-bale cotton, while others will produce a-half bale.
"Later fields won't see defoliation for another 2 to 3 weeks. Some of the crop will never catch up after standing in water early in the season.
"Verde plant bugs are showing up. But we're taking them out since we're already having to spray for brown stink bugs. Leaf-footed bugs are also doing some damage."
Megha Parajulee, Texas A&M AgriLife Extension Entomologist, Lubbock: "Most High Plains cotton is well into blooming. Some fields are beginning to cutout as water demand increases. The hot, dry conditions are bringing out the spider mite infestations, especially if they are located near maturing corn.
"Be watching for possible Lygus moving into cotton. Those populations are still high in non-cotton habitats that border fields. Shredding of roadside weeds, alfalfa harvesting, grazing of weeds by livestock and simply aging of roadside weeds all contribute to lygus bug movement. We have seen low numbers of lygus in most fields and numbers are below treatment thresholds. Cotton is generally safe from lygus injury 2 weeks after cutout.
"Large populations of beneficial insects are out there - including spiders, lady beetles and lacewings. If these natural enemies can be preserved, they should prevent the colonization of cotton aphids. However, as the season progresses and cooler temperatures return, cotton aphids may need to be monitored closely."
Chuck Wilbur, Independent Crop Consultant, Wellington, Texas/Southeastern Panhandle/Southwestern Oklahoma: "Cotton is trying to even up. We've had a week of hot weather, but we're still about a week behind. The dryland is getting close to cutout. It's blooming and there are 4 to 5 NAWF. It has a good fruit set but is stressing for water. The irrigated is all over the place, from 6 NAWF to 9. The lower lateral branches are starting to load up.
"We're running a lot of PGRs to hopefully regulate the plants. But it has been a creative nightmare trying to manage vegetative growth that's in 3 different stages in one field.
"There are some grasshoppers on the edges of fields and some bollworm moth flight but I can't tell if there's any damage. Most cotton is Bt.
"There are still lots of weeds. Residuals are gone and with all this rain - weeds just keep coming. Hoe hands are tired. They've been going 40 to 50 days. I'm surprised they're still around. I'm not sure I would be."
Mark Kelley, Texas A&M AgriLife Extension Cotton Specialist, Lubbock: "The majority of the cotton looks good. With the heat and low rainfall, some dryland is heading toward cutout at a rapid pace. Most dryland is still 6 NAWF and looking decent.
"Hopefully we'll get some showers early this week from the weather systems building up out west. The irrigated also looks good. I was in Lynn County this morning (8/10) and some subsurface drip irrigated fields were at 7 NAWF.
"I haven't heard of any major insect outbreaks. Guys are managing their PGRs in irrigated fields. For dryland, they should shy away from using PGRs, unless they have lost a lot of fruit and the crop is trying to get away from them. The dryland is getting stressed with little rainfall."
John Idowu, New Mexico State University Extension Cotton Specialist, Las Cruces: "If there were problems I would be receiving calls from farmers, and I haven't heard from any. Nothing jumps out.
"Recent rainfall has been good. But basically it just compliments the irrigation farmers obtain from the canal."
Glenn Aubrey, Aubrey's Farm & Ranch Consulting, Paris, Texas: "Our cotton is looking decent after being under pressure for a long time. But we will need the heat units in September to make a reasonable crop. With our cool, wet spring and early summer, we had some cotton not planted until late June. It's just now blooming. Plants are only about knee high. We need a rain really bad with the high heat we have had lately.
"I haven't heard of much bug pressure. With the stress this crop has seen, we don't need any insect problems."
Rex Friesen, Southern Kansas Cotton Growers Co-op, Winfield: "We're treating for tarnished plant bugs and finally finished treating for fleahoppers. We've also seen a few stink bugs, but I don't know of anyone treating for them.
"A few fields have been hurt by 2, 4-D drift, but not enough to cause heavy damage yet. Overall damage is very light.
"The crop is looking good. We've been getting rainfall and heat, which were needed after the slow start. Growers are applying a lot of PGRs. It's not at peak bloom yet, but we're seeing 6 to 7 NAWF. In most cases we have a terrific fruit load and an excellent crop."
Gaylon Morgan, Texas A&M AgriLife State Cotton Specialist, College Station: "Things are coming to an end quickly for the dryland crop in the Blacklands and further south. Even the irrigated has bolls popping pretty fast. Things are opening up in a hurry due to the lack of moisture and the heat index above 100.
"In Williamson County just east of Austin, cotton is about 60% open bolls. Today, (8/11) I drove by a field of PhytoGen 333 that is 70 to 80% open. It looks good.
"Defoliation is going out in Blacklands and we're doing some defoliation trials in Wharton County. We're fielding a lot of questions about defoliation and different defoliants."
Peter Dotray, Texas Tech University Weed Scientist (joint appointment with Texas A&M AgriLife), Lubbock: "Weed control has been good for a lot of farmers, despite all of the rainfall. The majority put out yellow herbicide and tried to keep ahead of weed flushes. Some have been able to maintain good control up to this point. I'm seeing some cultivation and layby treatments going out now to control weeds until the crop finishes.
"There aren't any good recommendations for treating resistant fields that have a lot of weeds, other than going in and chopping and making sure resistant weeds don't remain.
"One thing that's easily noticed is that where fields are clean, farmers are also controlling weeds around the fields. They're keeping populations down and making sure that resistant weed pollen and seeds don't move into the fields. But in not-so-clean fields, borders and bar ditches are heavy with weeds. Growers are anxious to put these weed challenges to rest."
Mark Hatley, Crop Quest Consulting, Dumas, Texas: "Cotton is looking good but needs to continue moving. We are at mid- to late-bloom. We've caught up some after the early rains and cool weather, but it's still mid August.
"I'm not really seeing insect pressure, but anything can happen with bugs this year. We could see spider mites moving out of corn into cotton or anything else.
"Sugarcane aphids have reached the northern Panhandle in Moore, Hansford and Ochiltree counties. We've had to spray for some in sorghum."
Marty Jungman, Independent Crop Consultant, West, Texas/Blacklands: "It's hot and dry and the older cotton is at cutout. Bolls are opening. We're about a week or two away from starting to defoliate. Our younger cotton planted in June really needs a rain in the next week to 10 days. It doesn't have much potential without the rain.
"Yields on older crop will be about 400 to 600 pounds. It's still hard to say on the youngest cotton.
"We're not seeing any late season insects on cotton. Some Sugarcane aphid problems are impacting grain sorghum harvest, but they aren't nearly as bad as last year."
Randy Norton, University of Arizona Extension Cotton Specialist, Tucson: "We had some heat stress last week and the first part of this week, but we're getting rain in southern Arizona today (8/11). Most cotton is on the backside of the bloom curve, so affects of heat stress are much less than if it had come in 2 weeks ago.
"Insect pressure remains light. Fellow researchers and entomologists are even having trouble getting insects in their trials. But there's another problem that farmers need to watch for - documented cases of glyphosate resistant pigweed. It's spotty in places, but it's here.
"Forecasters are predicting substantial rain in the fall and winter. We need the rain, but it could complicate harvest. I advise growers to think about what happened in the '70s and '80s when there was major fall precipitation, which caused the crop to deteriorate. They should get their crops finished and terminated in a timely fashioned."
