News about Integrated Pest Management in Hockley, Cochran, and Lamb Counties from Kerry Siders

Vol. 19 – No. 22

CROP & PEST UPDATE Well things are making progress, albeit slowly. Harvest of corn and grain sorghum is back in full swing. Peanuts continue to be dug and some combined. Peanut grades all over the board. Not certain what is going on with that? Cotton harvest aids are being applied pretty steadily now. I have not seen anything being stripped yet, but do anticipate some next week. Tuesday morning, October 14th dipped to 37 degrees. I did note some frost on a few buildings before sunrise and could smell a bit of leaf burn in the air. I would ask that if you note any unusual aphid activity in grain sorghum, particularly in eastern Lamb County, to please call me ASAP. We do have the Sugarcane Aphid very nearby. Also, I have noted a few spots of cotton aphids resurging in a few late cotton fields. I do not think it will amount to much with our night time temps, but worth noting. Wes Utley, Hockley County Extension Agricultural Agent, and I have a cotton harvest aid trial on the south edge of Levelland on the BJ Kennedy Farm. This field is just across the street from the Mallet to the north and just east of the new ballpark complex. These plots were sprayed on Oct 1st

, two weeks ago today. The plots are marked. Drive by and look. On the next page is a 7 and 14 day evaluation. After that are pictures of each plot. You will note that I do not have Sharpen in this trail. No slight intended, I just did not have that product at the time. I have looked a few fields treated with Sharpen and they do look very good. Sharpen requires a mentholated seed oil (MSO) plus an ammonium-based adjuvant (AMS). Always read and follow label directions and note certain restrictions and limitations on all products used.
