December 2, 2003
A large portion of the wheat crop was planted in two time frames. The wheat that was planted early and received timely rain developed rapidly if adequate fertility was available. An insect battle was necessary on some acreage to maintain an adequate stand. Some producers had to apply insecticides and other acreage had high levels of natural enemies. Shown below are pictures of mummified aphids and parasitic wasp(s) emerging from the aphid shell. The November planted wheat is progressing well and may provide some grazing in the near future, if weather allows for plant development.
Broadleaf weed control has been needed on a large portion of the early planted wheat. The control of broadleaf weeds is important to save the moisture and nutrients for the developing small grain crop. On some unsprayed acreage, thistle has grown large enough that the maximum rate of herbicide may only burn and knurl the plants instead of killing it. If you have a weed problem now, read the label closely and select the appropriate herbicide for the weeds needing controlled.
There are several dead and injured leaves on the developing wheat and it is causing producers some concern. The leaf damage is generally due to insects (aphids) and disease (leaf rust). Most of the leaf tip burn was caused by freezing temperatures that impacted the lush tender growth.
An inadequate amount of needed nutrients is apparent in some small grain acreage. When the need for nitrogen is not met in the developing small grain plant growth is slower than expected and plant coloration is light green to yellow. An application of nitrogen should be beneficial, however, producers should give special consideration to the type of fertilizer applied. Half of the nitrogen in ammonium nitrate is available at the time of application. This results in a quick response to the fertilizer applied. Other types of fertilizer have to be converted to a form used by the plant and this conversion is slowed by the cool temperatures.
Producers that are planning on grazing wheat need to make sure the secondary root system has developed. The secondary root system serves as an anchor for the plant and keeps the cattle from pulling the plants out of the ground. If there is no secondary root system, then grazing should be postponed until a later date.
I want to thank Warren Multer, Robert Scott, Steve Sturtz and Tommy Yeater, for their assistance in ginning cotton on November 24 at Lubbock. We were able to process 350 samples in seven hours due to the effort made by all counties. The gin sample sizes between 600 and 650 grams processed quickly with very few problems. Thanks again for taking the time to weigh and prepare your samples. I expect to receive the textile lab information in the near future. I will get these run through the spreadsheet and out to you as quickly as possible. I plan to send the results out as an e-mail attachment. That will allow you to insert the data tables into your result demonstration reports.
It was a busy year for cotton harvest aid work and I appreciate all the assistance provided by co-workers and producers. A summary of the work for 2003 is linked here.
