Garlic (Allium sativum) is one of the important bulb crops grown and used as a spice or condiment throughout India. Mostly garlic diseases are either soil- or seed-borne diseases. Among the garlic diseases fusarium basal rot and purple blotch diseases are most destructive diseases, and causes considerable loss in the yield and quality of the produce. An experiment was conducted in-vitro to evaluate the efficacy of five botanical extracts on the radial mycelial growth of Fusarium oxysporum f. sp. cepae, at three concentrations i.e., 5%, 10% and 15%, all the five botanicals exhibited significant mycelial growth inhibition of F. oxysporum f. sp. cepae, among five botanicals tested, significantly highest average mycelial growth inhibition was recorded with Ageratum conyzoides (89.5%) followed by Bryophyllum pinnatum (86.9%). A field experiment was conducted on selected bioresources which were treated on Fusarium basal rot and purple blotch diseases of garlic. Among all the treatments significantly reduced disease incidence of Fusarium oxysprum f.sp cepae (18%) and disease intensity of Alternaria porri (20.47%) were found in T6 (Microalgae+VC+SMC) followed by T3 (Microalgae). Similarly, among treatments T6 (Microalgae+VC+SMC) exhibited significantly highest average yield (132.58q/ha), plant height(74.6cm), number of cloves (21), bulb weight (30.0g), bulb diameter (5.61cm).
