In recent years, there has been increased demand for natural leaf cigar wrappers. Kentucky and Tennessee have been of recent interest as a new area for Connecticut Broadleaf production. Initial production experiences have shown that late-season frogeye leaf spot caused by the pathogen Cercospora nicotianae Ellis & Everh. may result in ‘green spot’ in cured leaf and cause a significant problem for producers of Connecticut Broadleaf cigar wrapper tobacco. Field trials were established in 2021 at Princeton, KY and 2022 in Mayfield, KY and Springfield, TN to evaluate effects of fungicide programs and lower leaf removal on wrapper production and frogeye leaf spot. Flutriafol, copper octanoate, and a program of alternating applications of mancozeb/azoxystrobin/mandipropamid were most effective in increasing yield of wrapper grades and would likely be effective in reducing late-season frogeye leaf spot. In 2021, there were significant reductions in total yield and gross revenue with lower leaf removal treatments. However, there were no significant differences found for wrapper production in 2021 or 2022 at the Kentucky locations. At Springfield in 2022, there were also significant reductions in total yield and gross revenue with lower leaf removal treatments. There were also no significant differences in wrapper production.
