Wheat

Last month's newsletter covered leaf and stem rust problems. Several counties had problems with stripe rust, however, as the temperatures increased and the humidity decreased, the threat of stripe rust outbreaks were reduced. Shown here are some pictures of stripe rust taken by Travis Miller.

Many producers choose not to invest in fungicides and baled the crop instead. Forage production on some acreage was very impressive.

The main problem being encountered by producers at this time is weed control in wheat to be harvested for grain. Some of the weeds rapidly growing at this time include:


Common Sunflower
Kochia
Texas Purple Thistle

Products that can be used as wheat harvest aids include:
Product name Company Use Rates
Per Acre		 Chemical Cost
Per Acre 		Comments
2,4-D Many 1 to 3 pints $2.70 to $7.50 Apply after the hard dough stage. Refer to label on grazing restictions and feeding straw.
Glyphosate Many 16 to 32 ounces $5.00 to 10.00 Apply after the hard dough stage of grain (30 percent or less grain moisture) and at least seven days prior to grain harvest. CAUTION: Do not apply to wheat grown for seed as a reduction in germination and vigor may occur.
Ally DuPont 0.10 ounce $2.70 to $3.25 Used in a tank mix with 2,4-D or Glyphosate to improve the desiccation and kill of the weeds treated.


NOTE: Be sure to follow label directions!

Cotton

Cotton planting has begun with the soil temperature already above 65 degrees for a 10 day average on April 31. Several producers have commented that the cotton is slow about coming up and growing. The main reason for this is lower soil and air temperature compared to a normal planting date the third week in May. In many fields the emergence time has been 10 to 14 days.

The annual cotton insect scout school will be held June 4, 2001 at the Texas A&M Research and Extension Center at San Angelo. If you would like to travel to Uvalde, Texas to fine-tune your scouting skills, please contact Rick Minzenmayer at (915) 365-5212. If you or your producers are planning to attend please pre-register with Rick before coming.
