ABSTRACT
Foliar application of five plant defense activators i.e., salicylic acid, citric acid, benzoic acid, KH2PO4 and K2HPO4 were tested against potato leaf roll virus (PLRV) in field conditions while two nutrient solutions i.e., macronutrients (N, P, K) and micronutrients (B, Zn, Cu, Mn, and Fe) were tested against the disease under glass house conditions during the years 2018 and 2019. All plant defense activators and nutrients were sprayed thrice using three different concentrations (0.25%, 0.50%, 0.75%) with 15-days interval. Although all activators were found effective to manage PLRV with some variations, but maximum disease was managed by salicylic acid with 0.75% concentration. In case of nutrients application, both solutions were found to be effective against PLRV but macronutrients solution with 0.75% concentration was found more effective than micronutrients solution to manage PLRV. It is advised to get better results against PLRV that both macro- and micro-nutrients should be sprayed in combination.
