Efficacy of the new soil fumigant dimethyl disulfide (DMDS) was studied in 2013–2014. Accolade/Paladin® was assessed to control Verticillium dahliae on chrysanthemum. DMDS decreased significantly Verticillium wilt incidence in the treated plots. DMDS increased significantly the number of marketable chrysanthemum stems. DMDS decreased the presence of V. dahliae in asymptomatic residual stems.
