Leaf blight caused by Colletotrichum dematium is one of the serious diseases which causes quantitative as well as qualitative losses. Effect of various diseases management tools were tested as a part of suitable option for managements of leaf blight of safed musli. Eight fungicides viz., propiconazole (0.1%), mancozeb (0.25%), penconazole (0.1%), carbendazim (0.1%), copper hydroxide (0.2%), curzate M8 (0.2%), chlorothalonil (0.2%), thiophanate M (0.2%) and seven botanicals viz., Bael (Aegle marmelos), Ghaneri (Lantena camera), Karanj (Pongamia pinnata), Kanher (Nerium oleander), Mehandi (Lawsonia innermis), Nilgiri (Eucalyptus spp.) and Neem (Azadirachta Mica) tested at 5 and 10 percent concentration, respectively. Among fungicides propiconazole and penconazole showing 100 percent inhibition as against control. Among botanicals at 5 and 10 percent concentration the extracts of Eucalyptus spp. showed maximum growth inhibition (78.90%, 84.07%) followed by Aegle marmelos (77.04%, 82.47%), respectively. The Lawsonia innermis was found least effective against test pathogen at both level of concentrations.
