    Potential fungicides and biocontrol agents to manage target spot (Thanatephorus cucumeris) on flue-cured tobacco in Virginia

    JOHNSON C.S.
    Virginia Tech, Southern Piedmont Agricultural Research and Extension Center, Blackstone, VA, U.S.A.
    Target spot (Thanatephorus cucumeris) remains a threat to flue-cured tobacco production in Virginia, and field experiments since 2001 have sought to identify effective fungicides for target spot control. Trials in 2017-2019 included fungicides from...
