Abstract: Fusarium solani considered as an aggressive pathogen widely dispersed in soil and causes root rot disease in papaya plant which is responsible for the estimated loss up to 40-95 per cent. In the present study, six fungicides at different concentration viz; 50, 100 and 150 ppm were evaluated against five isolates of Fusarium solani (Fs-I to Fs-V) causing papaya root rot by applying poisoned food technique in the laboratory of the Department of Plant Pathology, DRPCAU, Pusa, Samastipur in 2016. Observation of the experiment was taken at 240 hours for the assessment of their inhibitory effect. The data revealed that all the fungicide (contact and systemic) significantly reduces the mycelial growth of Fusarium solani isolate over control but Carbendazin 50% WP @150 ppm found effective with Fs-I (95.3%), Fs-II (94.9%), Fs-III (95.1%), Fs-IV (94.9%) and Fs-V (95.5%) mycelial growth inhibition over control followed by Propiconazole, Hexaconazole, Mancozeb, Copper Oxychloride. However, Azoxytrobin shows minimum inhibition per cent against all isolate Fs-I (75.0%), Fs-II (70.3%), Fs-III (74.5%), Fs-IV (71.5%) and Fs-V (74.4%) over control respectively.
