Abstract

The experiment was conducted at Department of Plant Pathology, S.K.N. College of Agriculture, Jobner (Rajasthan). Alternaria alternata was isolated from leaves of tomato and observed to be pathogenic under artificial conditions. It is cause heavy yield loss in rajasthan as well as in india. Among five systemic acquired resistance activators, salicylic acid was found most effective against Alternaria alternata in vivo conditions followed by, 2,4 Dichloroisonicotinic acid. All treatments as foilar spray were able to reduce disease severity over untreated control.
