Lots of weeds and many acres needing to be planted. An application of 12 ounces of Roundup Ultra Max will kill a high percentage of the emerged weeds and leave the seedbed firm and moisture intact. Plowing is a non-chemical option, but your related equipment, tractor, and diesel expenses will be higher than the cost of the herbicide and application.

The producers that have already planted may have a lot of broadleaf weeds emerging. If you are using a hormone herbicide such as 2,4-D you need to look at the specific label before applying it to wheat or other small grains to control broadleaf weeds. Most of the 2,4-D labels indicate that the wheat needs to be past the tillering stage before applying the herbicide. You may need to switch over to some other class of herbicide (example: Ally or Amber).

During October, most of our counties received 4 to 9 inches of rain. The wheat to this point and time looks healthy but warmer temperatures that stimulate growth may result in the wheat crop showing signs of nitrogen deficiency. Most of the available nitrates have leached below the root zone and the plant will suffer until the root expands far enough to extract the deeper nitrates or until an application of nitrogen is made.

Hopefully, when you picked up your small grain seed for result demonstration tests from Abilene Ag, you thanked Dub Vinson for handling the separation and storage of the seed until you were ready to plant. His assistance helps reduce the need to travel to San Angelo to obtain your small grain seed.

Grazing of wheat should be delayed until the secondary root system has developed enough to anchor the plant. If producers start the grazing process too early the livestock will pull the wheat plant up by the roots and reduce the plant population. Producers should examine the wheat plant and determine if the secondary root system has adequately developed before livestock are allowed to graze.

Most of the early planted wheat is lush and rapidly growing and vulnerable to a freeze. When the first freeze occurs, tip burn will give the field a yellowish bronze color, however, the wheat will return to a green color in a couple of weeks as the injured leaves are hidden by the new plant growth.

Scott Anderson and I are planning to establish a Ryegrass Control Demonstration between Bangs and Brownwood. This test will include nine replicated treatments. Additional test work at the site is being considered by Bayer Corporation.


The rainfall in October resulted in additional cotton plant development in 150,000 acres of cotton. The removal of juvenile growth can only be achieved using 5 ounces or more of Ginstar. The juvenile growth could be desiccated using 1 ounce of more of Aim. The cooler air temperatures slowed the development of the abscission layer and that delayed the followup treatment of paraquat (Cyclone Max, Boa, etc). The expense of many of the harvest aids kept producers from using them. Harvest on many dryland acres will not occur until after the first killing freeze.

Our dates to gin cotton at Lubbock are set for November 18, 19, and 20, if you can assist with this activity let me know; we will need four people to cover the various stations. I need to let all the cotton producing counties know who is going so they can make the necessary arrangements to drop off their gin samples. Attached is a blank gin sheet that will need to be filled out and sent with your cotton samples. The seven digit sample number is a combination of three numbers; the county number is the first three digits, the producer or plot number is digits 4 and 5, and the sample is assigned a number between 01 and 99 which makes up digits 6 and 7. By using this code it helps to keep samples from getting lost. Try to have your gin samples between 600 and 800 grams. Thanks.
