Abstract
A field survey was conducted to find out the incidence of foot and root rot of betel vine caused by Sclerotiumrolfsiiunder prevailing environmental condition in major betel vine growing areas of Bangladesh. The areas were Gouranadi, Kaligonj, Mirpur, Mohanpur and SitakundaUpazila under the district of Barisal, Jhenaidah, Kushtia, Rajshahi and Chittagong, respectively. The incidence of foot and root rot disease varied remarkably and ranged from 4.53 to 15.46% in different upzillas. The maximum incidence of 15.46% was recorded from Gouranadi where soil pH was 5.4, ambient temperature was around 32oC, relative humidity was 82% and light intensity was 53x100 lux. The lowest incidence of the disease was observed as 4.53% from Sitakunda where soil pH was 6.6, ambient temperature was 28oC, RH was 72% and light intensity was 74x100lux. The incidence of foot and root rot of betel vine was high in the areas where soil pH and light intensity were low and temperature and relative humidity were high.
