The study was conducted to develop an effective management strategy against the devastating potato late blight. Of the three management modules tested in the field conditions for two consecutive growing seasons, rabi 2014-15 and rabi 2015-16, the module T3 consisting of soil application of bio-agents (1 kg each talc formulation of Trichoderma harzianum and Pseudomonas fluorescens enriched in 100 kg well decomposed FYM) 15 days before planting, tuber treatment with Mancozeb @ 0.25%, prophylactic spray with Mancozeb @ 0.2% twice at weekly interval before onset of the disease followed by curative sprays with Cymoxanil + Mancozeb @ 0.3%, Dimethomorph @ 1.0% + Mancozeb @ 0.2%, and Fenamidone + Mancozeb @ 0.3% at weekly interval at onset of the disease was found most effective and recorded least disease severity and higher yield compared to other modules. Hence, this module serves as effective management strategy against the disease under field conditions.
