TAILIEUCHUNG - In vitro efficacy of botanicals and biocontrol agents against early leaf blight in tomato

Early blight is potentially destructive disease in tomato occurring on the oldest leaves as small, brownish which are due to foliar blight disease and it was caused by a foliar fungal pathogen Alternaria solani. The disease causes considerable yield as well as post-harvest losses. A. solani produced blackish, fluffy mycelium with septate, beaked conidia on PDA Eight plant extracts and four biocontrol agents were evaluated following poison food technique and dual culture. Garlic+Neem+Datura and only garlic extract induced 100% growth reduction at 10% and 20% concentrations for the test pathogen followed by Datura leaf extract (10% and 20%) reduced the growth of Alternaria solani to and . Neem leaf extract had approximately no effect on the inhibition of radial growth of Alternaria solani with only and growth inhibition in 10% and 20% concentration, Pseudomonas fluorescens recorded maximum growth inhibition () against A. solani followed by Trichoderma viride inhibited () growth of A. solani. Least growth inhibition observed for Trichoderma hamatum () among four bioagents. | In vitro efficacy of botanicals and biocontrol agents against early leaf blight in tomato
