Abstract:
Study of Salicylic acid under in vitro condition resulted that SA at 200 ppm (68.45%) concentration was most effective in inhibiting mycelial growth followed by 150 ppm (46.98%) concentration. For activation of defense mechanism of plants, salicylic acid was evaluated through interaction between root dipping and foliar spray. Salicylic acid was proved to be most effective in treatment combination (root dip of 200 ppm and foliar spray of 150 ppm) against Alternaria solani and recorded minimum per cent disease intensity i.e., 17.41%, 20.43% at 45 DAS and 60 DAS, respectively.
