dc.description.abstract | Sclerotinia sclerotiorum is one of the most devastating pathogens causing severe crop losses on various economically important leguminous, solanaceous and cole vegetables. Its incidence has been recorded up to 20% on french bean and dolichos bean in research farm, ICAR-IIVR, Varanasi during cool and moist climate in 2016. Initial disease symptoms appeared in the form of water-soaked lesions on stem during the flowering and pod formation stages. Later it expanded rapidly on infected plant parts including leaf, flower and pods, finally caused girdling and rotting of these parts. Lesions of infected plant parts usually developed patches of white, fluffy mycelial mats often with large, irregular, black coloured sclerotia. Different isolates of S. sclerotiorum wereisolated from French bean (3), dolichos bean (1) and pea (1) on potato dextrose agar and purified by hyphal tip method. These isolates were subjected to cross infectivity test on different leguminous hosts uz. French bean, dolichos bean, cowpea, sword bean and pea adopting leaf detachment method. Under in vitro condition, the surface sterilized leaf and pod of these leguminous vegetables aseptically inoculated with 5 mm mycelial bit of five days old pathogen culture and observed for colonization of pathogen after 2 days of incubation at 181°C. It was observed that inoculated pathogen isolates infected leaves of all the tested hosts with maximum severity on the cowpea leaf. However, infection level was more on pods of dolichos bean than that of pea. It clearly revealed cross infectivity of the pathogen indicating the emergence of this pathogen as broad spectrum coverage wide host range. | en_US |
