The lack of rain in September delayed the establishment of small grains. It did give producers time to get the seedbed prepared. The hot temperatures in September allowed for a quick desiccation of weeds which often serve as a host to insects and diseases. The wheat curl mite is associated with the distribution of Wheat Streak Mosaic Virus. The wheat curl mites find the volunteer wheat and grasses a good home and then move to the planted wheat as it emerges.

In the Southern Rolling Plains, mid-October until mid-November is the ideal planting time for wheat intended for grain production. With excellent soil moisture and warm soil temperatures, the plants should germinate uniformly if they are planted at the correct depth in a firm seedbed. Most of the bearded varieties need to be planted from 1.25 to 1.75 inches deep. Beardless varieties can tolerate being planted deeper, however, anything over 2.5 inches is too deep. Trying to plant wheat at a uniform depth is very difficult in freshly worked soil. Producers need to develop the practice of developing the seedbed early and allowing it to settle for several weeks before planting.

The harvest aid test in Runnels County alerted producers to the fact that the cotton with regrowth is a challenge this year and we will have to modify the ground rig nozzle configuration. The nozzle over the top of the row can be a flat fan nozzle of your choice. Drop nozzles used in the furrows directed toward the middle to lower portion of the cotton plant will be needed. The nozzle of choice will be the one that gets the best coverage of the harvest aid applied. Pressure for application may be 50 to 80 p.s.i. to get the needed coverage. Off target drift will be a concern! For desiccation/abscission of juvenile growth, producers will need to select Ginstar, Aim or ET. If adequate time exists for the juvenile leaves to mature before applying a harvest aid then paraquat can be used to desiccated the leaves.

One big harvest aid decision for producers is whether to defoliate. The leaf grade discounts are high enough that most producers are concerned. In most cases they can't afford to kill the leaves and have them remain on the plant. For defoliation, there are several good defoliants to choose from. Some producers are applying a light rate of desiccant and then after a majority of the leaves have fallen off applied a high rate of desiccant to prepare the crop for harvest.

Fisher, Jones, Nolan, Runnels, and Tom Green Counties indicated that they had cotton samples that will need to be ginned at Lubbock in November. A total of 330 cotton samples have been called in so far. If your county is not listed I still need your best guess to determine the number of days we will need the gin. The ginning dates for Districts 6 and 7 will be in late-November. Don't forget, when your preparing the samples for ginning, the best weight size has been approximately 600 grams. If you need a copy of the ginning sheet [Click Here].

Harvest aid demonstrations were established in Tom Green, Runnels, Howard, and Jones Counties for county crop tours. The final report for Tom Green County, Runnels County, Howard County, Nolan County and Jones County are linked. The treatment names that are underlined in the table are linked to a picture of that treatment. I want to thank all the Extension Agents that assisted in the plot designs and establishment, their names are listed on the reports. Enjoy the virtual tour! The information obtained from these plots were useful in discussing harvest aid selection for boll opening, defoliation, and/or desiccation.

Pesticide Recertification Training

On October 10 there will be a training conducted at Abilene for producers needing to obtain a Private Applicators license. For more details and to register for the meeting, call Gary Bomar at (325) 672-6048.

November 30, a seven hour CEU course will be held at Eldorado.

December 8, a five hour CEU course will be held at Brady.

December 14, a five hour CEU course will be held at Abilene.

For Your Information

On the first Monday in December the Old Time Friends of Extension luncheon is held in San Angelo. I have attended this meeting every year for the last 16 years. It has been worth my time and effort to attend. If you want more information give me a call.
