Chrysanthemum wilt is one of the most destructive disease causes heavy yield loss every year. The field survey was carried
out during 2012 in the region of Kalenahalli, K.R. Nagar Taluk, Mysore District revealed the occurrence of wilt disease.
The symptoms include stunted growth of the plant, wilting of leaves, reduction in flower size and unequal opening of flowers.
The pathogen associated with the disease was isolated and identified as species of Erwinia. In vitro evaluation of chemicals
revealed that Streptomycin sulphate at 1.0% (19.3mm), Carbendazim at 6% (20.55mm) and Mancozeb at 2% (22mm) inhibited
the bacterium. Further work is in progress to evaluate the same in vivo with different concentrations for the management of
