Author:  Comments Off on Insect Calls of the Week (August 1, 2019)

I don’t think I have had a call about soybean all week, but my observations suggest we need to be scouting for stink bugs in our earliest beans, and in some areas, kudzu bugs.

Sulfur deficiencies in cotton

Author:  Comments Off on Sulfur deficiencies in cotton

Over the past month, I’ve received several images of sulfur deficiencies in cotton.  While we are quickly approaching a point in which a sulfur fertilizer application will be unable to impact yield in 2019, understanding what a sulfur deficiency looks like may help identify areas which will likely respond to the nutrient during the 2020 season.  This blog covers the characteristics of a sulfur deficiency, presents atmospheric deposition data, and highlights current UT recommendations for the nutrient in cotton production.
