Five fungicides such as rovral, bavistin, cupravit, dithane M-45 and thiovit were tested against conidial germination of Fusarium oxysporum. Dithane M-45 was the most effective against the fungus. Rests of the fungicides were more or less effective in the inhibition of conidial germination after 5~30 minutes immersion in 500~2500 ppm concentration. Five plant extracts(leaf extracts of Ocimum sanctum, Lantana camera, Calotropis procera, Azadirachta indica and Vinca rosea) found to be more or less effective against the fungus. 'Dhup' somke have good inhibitory effect on conidial germination of F. oxysporum.

Twenty plant extracts were tested against mycelial growth, sclerotium formatiom and dry weight of mycelium with sclerotia of Sclerotium rolfsii Sacc. The highest(90 mm) mycelial growth was measured in Adhatoda vasica, Tegetes erecta, Allium cepa, and Curcuma longa. The lowest(25 mm) was in Azadirachta indica. No mycelial growth was found in any concentration of cow, buffalo, and goat urine. The highest(90 mm) and the lowest(15 mm) mycelial growth were measured in Biomil and Urea, respectively. No mycelial growth was observed in Zinc. The highest(60 mm) and the lowest(2 mm) mycelial growth were recorded in Macuprex(Dodine; 65% WP) and Boron(100% Boric acid and 17% Boron) respectively. Mycelial growth was totally inhibited in Rovral(Iprodione; 50% WP).
