Evaluation of Insecticide Resistance in Tobacco Thrips Populations and Plant Density Effects on Thrips Injury to Cotton

Our departmental seminar speaker this week is Jessica Krob, who will be presenting her M.S. Proposal Seminar titled “Evaluation of Insecticide Resistance in Tobacco Thrips Populations and Plant Density Effects on Thrips Injury to Cotton”. Join us at 10:30 am EST/9:30 am CST on Friday, April 16, 2021, via the Zoom link information that is provided at the end of this message. Seminar Abstract: In Tennessee, thrips rank among the top four insect pests of cotton, which is one of the top three cash crops grown in the state. Thrips management is necessary because their feeding injury can lead to delayed maturity and yield loss to cotton. This research will investigate two recent observations made in small-plot field trials in Tennessee. The first observation is

Fungicide Sensitivity Screening of Corynespora cassiicola in Soybean and Cotton

Our departmental seminar speaker this week is Ty Smith, who will be presenting his Ph.D. Exit Seminar titled “Fungicide Sensitivity Screening of Corynespora cassiicola in Soybean and Cotton”.   Seminar Abstract: Target spot, caused by the fungus Corynespora cassiicola, is a foliar disease of cotton and soybean.  Target spot has become a disease of concern in soybean and cotton production systems. Data for fungicide sensitivity and understanding potential impact on yield is lacking for C. cassiicola.  With the lack of knowledge about baseline fungicide sensitivity the objectives of this study were: (i) to evaluate fungicide products and mixes in small plot trials, (ii) develop baseline fungicide sensitivity data on C. cassiicola isolates from Tennessee soybean and cotton, (iii) investigate the interaction of malathion with DMI fungicides on target
