Summary

​The presentation will provide consultants and farmers with valuable information regarding the symptoms of bacterial blight of cotton as well as the mechanisms that allow the disease to occur, thrive and spread in a cotton field. More specifically, the situation that has occurred during the past two seasons in the Mid-southern U.S. whereby an increase in the occurrence of bacterial blight will be highlighted. The distribution of the disease during 2011 and 2012 as well as potential management alternatives that can include resistant cotton cultivars as well as tillage practices will also be briefly discussed. In addition, viewers will be briefed regarding the new research project to provide cotton farmers with a valuable method to screen commercially available cotton cultivars for the presence of the bacterium in cotton seed.

About the Presenter

Tom AllenTom Allen received his BS in biology from Indiana University in Bloomington, IN in 1994. He received MS and PhD degrees from Auburn University in forestry and plant pathology in 1999 and 2003, respectively. Since graduation he has been a post-doctoral research associate with The University of Georgia at Griffin (2003-2005) where he worked on yeasts present in the phylloplane of turfgrass as potential biocontrol agents with Dr. James Buck and Dr. Lee Burpee. In 2005 he moved to Amarillo, TX and joined Dr. Charlie Rush’s research program as an Assistant Research Scientist with Texas A&M University in Amarillo/Bushland, TX (2005-2007). Allen worked exclusively on Karnal bunt of wheat in wheat fields around Phoenix, AZ. In 2007, Allen joined the faculty at Mississippi State University at the Delta Research and Extension Center in Stoneville, MS as an Extension Plant Pathologist for the major row crops grown in the Mississippi Delta including corn, cotton, grain sorghum, rice, soybean, and wheat. In 2008 his appointment changed and is currently 80% extension and 20% research. He has been a member of APS and the Southern Division of APS since 2000. He has also been actively involved in the Mississippi Association of Plant Pathologists and Nematologists, Southern Soybean Disease Workers, and several regional projects including NCERA-208 (response to emerging threat: soybean rust), NCERA-212 (soybean diseases), and NCERA-184 (management of small grain diseases). Allen has been active in bacterial blight of cotton research since 2011 and will continue research and extension efforts into the potentially destructive disease in the future.
