In vitro assessment of fungicides and plant extracts against common bean anthracnose incitant

Common bean Anthracnose is a destructive and devastating disease, which leads to decline in quality as well as well quantity in the crop yield across the globe. It is hard to manage because of its seed and soil borne nature. In order to delineate the efficient strategy for the management of common bean anthracnose an in vitro study for evaluating the efficacy of various non-systemic, systemic, combo fungicidal formulations and plant extracts was carried out. Evaluation of these fungicides and plant extracts against the target pathogen was done as per the guidelines of poisoned food technique. From different non-systemic fungicides mancozeb 75 WP was found best in inhibiting the mycelial growth of Colletotrichum lindemuthianum (75.63% mean inhibition), among systemic fungicides carbendazim 50 WP was found best (85.13% mean inhibition), among combo fungicides mancozeb (63%) + carbendazim (12%) gave maximum values for mycelial growth inhibition of Colletotrichum lindemuthianum (89.05% mean inhibition) and among plant extracts clove extract of garlic was found best (65.33% mean inhibition).
