Abstract

Leaf and flower blight of marigold incited by Alternaria zinniae Pape is one of the most important diseases of marigold under terai agro-climatic zone of West Bengal. Mancozeb 75%WP (Indofil M-45), Metalaxyl 8% + Mancozeb 64%WP (Tata master) and Carbendazim 12% + Mancozeb 63%WP (Companion) @ 200 ppmeach totally inhibited the mycelial growth of the pathogen in in vitro condition over untreated control whereas, Bordeaux mixture (Copper sulphate and Lime), Carbendazim 5O%WP (Bavistin) and Copper Oxychloride 50%WP (Blitox) at 500ppm each exhibited 54.10,55.73 and 63.93% mycelial groWth inhibition of the pathogn respectively. Mancozeb 75%WP (Indofil M-45) @ 0.25%, Carbendazim 12% + Maneozeb 63%WP(Companion) @ 0.10% and Metalaxyl 8% + Mancozeb 64%WP (Tata master) @ 0.10% reduced the disease incidence by 87.52, 85.18 and 84.60% respectively under in vivo condition.
