Garlic commonly known as ‘Lasan’ is the second major important bulb crop grown and used as a spice or condiment, next to onion in India. Among different fungal diseases of garlic, Purple blotch caused by Alternaria porri has currently become one of the most important disease of all garlic varieties. Loss due to the disease has been huge and varying on different factors. Therefore, present investigation was undertaken for the management of Purple blotch. Botanicals and Trichoderma viride were evaluated for their efficacy under in vivo against Purple blotch incited by Alternaria porri. Trichoderma viride followed by neem oil showed minimum disease spread than rest of treatments. Effects of different botanicals and Trichoderma viride was evaluated on different growth parameters of garlic crop under field condition at Prayagraj during Rabi 2019-2020. Maximum plant height @ 30 DAS (38.30 cm), 60 DAS (54.50 cm) and 90 DAS (57.56 cm) and maximum number of leaves @ 30 DAS (5.60), 60 DAS (5.87) and 90 DAS (5.93) was obtained by the treatment with Trichoderma viride. Among the treatments, Trichoderma viride was found most effective in inhibiting the percent disease intensity by upto 73.60% inhibition of purple blotch of garlic, followed by Neem oil as compared to rest all treatments and control.
