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
