Fixed boroj survey was conducted during 2016 & 2017 in Mitha pata variety of Betelvine across four Blocks of South 24 Parganas District in the Coastal Saline Zone of West Bengal, India. Among the four diseases surveyed, highest incidence of Sclerotium collar rot (SCR) and maximum severity of Phytophthora leaf rot (PLR), Colletotrichum leaf spot (CLS) and Xanthomonas leaf spot (XLS) was recorded as 17.67±3.18%, 14.40±0.46%, 6.40±0.46% and 9.33±1.54%, respectively. Kakdwip Block showed consistently higher incidence of SCR (mean incidence 12.00±0.99%), whereas severity of leaf rot and leaf spots were maximum in Namkhana (mean PDI 10.00±%0.71) and Patharpratima (mean PDI of CLS 3.55±0.61% and XLS 4.67±0.82%), respectively. Where collar rot was mostly confined to the summer months (March to June), the leaf rot and leaf spot diseases were more prevalent in rainy season (July to October.
