Description :
Foot rot caused by Phytophthora capsici is the most destructive disease of black pepper (Piper nigrum L.) and it affects the total production in all black pepper growing areas. Despite many fungicidal recommendations, the disease control is still a matter of concern. Hence it is important to incorporate more effective fungicides in the disease management plan. In the present study, twelve different fungicides and a microbial consortium were evaluated for their efficiency in suppressing P. capsici in black pepper. Fungicides differ in their efficiency in reducing P. capsici infection when applied before and after infection initiation. Dimethomorph 9% + Mancozeb 60% WP and Fosetyl Al 80%WP were found to be the best fungicides to manage the disease prophylactically as well as after the commencement of disease. Cymoxanil 8% + Mancozeb 64% WP, Fenamidone 10% + Mancozeb 50% WG, Kresoxim methyl 44.3% SC and Iprovalicarb 5.5% + Propineb 61.25% WP also provided more than 80% control when applied prophylactically and 50% or more control when applied after initiation of the disease. Application of microbial consortium was found effective only when applied prophylactically.
