Abstract:

The present investigation was undertaken for the management of Alternaria leaf spot of brinjal using bio-agent, botanicals and a fungicide (treated check) were evaluated for their efficacy under in vitro and in vivo against Alternaria leaf spot of brinjal incited by Alternaria solani. The antimicrobial activity of four plant extractsNeem (Azardirachta indica), Onion (Allium cepa), Garlic (Allium sativum) and Datura (Datura stramonium) were tested against test fungus Alternaria solani. Garlic bulb extract showed minimum radial growth and maximum mycelial inhibition @ 5 and 15 per cent concentration. The dual culture result revealed that Trichoderma harzianum is an antagonistic to Alternaria solani. At 30, 60 and 90 DAT readings were taken for growth parameters and per cent disease intensity. Among the treatments, Trichoderma harzianum was found most effective in the percent disease intensity of brinjal, followed by Neem leaf extract as compared to carbendazim 50 WP (treated check) and control. The maximum yield were found to be in Trichoderma harzianum, followed by Neem leaf extract and Datura leaf extract as compared to Carbendazim (treated check) and control.
