Effect of biocontrol agents and fungicides against anthracnose of French bean caused by Colletotrichum lindemuthianum (Sacc. and Magn.) in mid-hill of Garhwal Himalaya

Abstract

Evaluated the efficacy of different bioagents and fungicides used as seed treatment and foliar spray, tested alone and in the combination. Ten treatments including control were tested against French bean anthracnose caused by Colletotrichum lindemuthianum. Among all these treatments minimum per cent disease incidence (PDI) and per cent severity index (PSI) were recorded in alone Carbendazim (8.33,11.66 and 18.30%) and in combination Carbendazim +P. fluorescens (16.00, 26.33 and 39.33%) at 55, 75 and 95 DAS. Minimum (PSI) at 55, 75 and 95 DAS were recorded in alone i.e. (4.58, 7.41 and 10.11%) and in combination (9.11, 16.54 and 21.00%). Highly PDI and PSI had observed in the control compare to all other treatments.
