Positive role of salicylic acid and trichoderma on the enhancement of systemic acquired resistance (SAR) and induced systemic resistance (ISR) in maize – Exserohilum turcicum pathosystem under greenhouse condition

Systemically acquired resistance (SAR) and Induced systemic resistance (ISR) agents can trigger host system to produce phenolic compounds, PR proteins, sugars which impart resistance in plants against invading pathogens. The application of different concentrations of salicylic acid and Trichoderma viride (Tri-25) viz., single inoculation, combination inoculation with challenge inoculation of Exserohilum turcicum on the enhancement of growth and management of disease with special emphasis to ISR and SAR against turcicum leaf blight disease.
