Efficacy of ISR chemicals/elicitors against Pythium aphanidermatum causing rhizome rot of turmeric

Abstract

All the ISR chemicals/elicitors tested as rhizome treatment and soil application against turmeric rhizome rot were found effective with reduction in pre and post emergence mortalities of P. aphanidermatum, over untreated control. however, Chitosan (RT) + its drenching (97.25 %), followed by Salicylic acid (RT ) + its drenching (96.07 %), Chitosan (RT) (94.29 %), β-amino butyric acid (RT) + its drenching (93.56 %), Jasmonic acid (RT) + its drenching (92.27 %), Salicylic acid (RT) + Propiconazole (SA) (91.72 %) and Salicylic acid ( RT ) (91.61 %). Whereas, Control (Propiconazole (RT)) was recorded comparatively least reduction in average mortality of 77.13.
