Field experiments were carried out for three consecutive years i.e. 2009-2010, 2010-2011 and 2011-2012 at Horticultural College and Research Institute, Anantharajupeta, to study the effect of different fungicides for the management of foliar blight of chrysanthemum. Among different fungicides tested, tebuconazole @ 0.1% recorded lowest per cent disease index (PDI) and highest flower yield followed by propiconazole @ 0.1% and azoxystrobin @ 0.075%. The PDI was highest with lowest flower yield in control. In other fungicides PDI was in the range of 26.66 – 31.10. The B : C ratio of tebuconazole, propiconazole and azoxystrobin was 5.55, 4.56 and 4.19 respectively.
