April 2, 2004


I have looked at several fields and submitted plant samples that have had problems with leaf rust. Information on the leaf, stem and stripe rust problems was discussed in the March 1, 2004 newsletter.

Several wheat diseases are being discussed by producers. Some of the better web sites for increasing your knowledge on the subject include:


I am trying to get an idea of how many small grain samples we will be thrashing this year, if you have a test plot that has survived and plan to harvest samples and thrash them at the research center in San Angelo, drop me an e-mail and let me know. THANKS!

For those producers with thin stands of wheat intending to plant into residue, an application of Glyphosate (12 to 24 ounces) does a good job. Contact herbicides can be used, however, producers need to increase the gallons of water applied per acre to get complete coverage of the wheat and weeds.


Cottonseed for variety tests have been ordered. Linked is a listing of the tests to be conducted in Districts 6 & 7.

A number of producers have indicated that they planned to plant early this year. Remind them that the minimum soil temperature for planting cotton is a 10 day average of 600 F at an eight inch soil depth (take temperature at 8:00 a.m.). When soil temperatures are 65 to 700 F the cottonseed germinates and emerges quicker which helps to reduce the amount of time emerging seedlings are exposed to soil diseases. If cotton is planted at the minimum soil temperature and then watered, you will probably have a reduction in the final plant stand and health of the crop.

Pesticide Recertification Training

On Monday, April 12, 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.

Weed ID Web Sites

A number of people have been asking about weed identification sites. A good reference is linked here. These are listed on the Texas Weed Information Group web site (http://twig.tamu.edu).
