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 a mind-set that wheat ground should be worked early and allowed to settle for several weeks before planting.
Producers need to pay close attention to weed problems. With favorable growing conditions, a high population of weeds could develop rapidly and the larger the weeds the more expensive they are to control. Producers will need to be reminded not to use 2-4,D until tillering is complete. They might consider using products like Ally or Amber that are reasonably priced and give favorable broadleaf weed control for several months.
The August rains prompted the emergence of volunteer wheat which can serve as a host to several problems. The wheat curl mite is associated with the distribution of Wheat Streak Mosaic Virus. The wheat curl mite find the early emerging wheat a good home and then move to the planted wheat as it emerges. Hessian fly will have an opportunity of getting started early which will allow multiple generations to develop and this can be a big problem. Also, the volunteer wheat can serve as a host to leaf rust that can become a serious problem if the wet cycle continues this fall.
The biggest decision for producers is whether to defoliate. The leaf grade discount 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, some producers are applying a light rate of desiccant while others are applying defoliants. After the leaves have fallen off the plant, then a desiccant is applied at a high rate.
I did not get much of a response from last month's request concerning the number of cotton samples that will need to be ginned at Lubbock in November. 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 you are 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].
On October 11, 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 six hour CEU course will be held at Eldorado.
December 6, a five hour CEU course will be held at Burnet.
December 9, a five hour CEU course will be held at Brady.
December 15, a five hour CEU course will be held at Abilene.
