Abstract: Six fungicides viz., cupravit, thiovit, dithane M-45, bavistin, rovral and suncozeb were tested against C. gloeosporioides. Dithane M-45, rovral, thiovit and suncozeb were the most effective ones. Cupravit and bavistin were less effective in the inhibition of conidial germination. Ten plant-extracts considered as fungicides were tested, out of which Tagetes erecta leaf and Azadirachta indica bark extracts were the most effective in inhibiting Colletotrichum gloeosporioides after 5-30 minutes of immersion and in 5:1.25 (w/v) concentration. The phytohormone IAA had great effect against the inhibition (100%) of C. gloeosporioides at 0.005 to 0.006% concentration for an immersion after 5-30 minutes. Rest of the hormones also had good effects against C. gloeosporioides.
