Abstract

It is assumed that the presence of wax on castor predispose the crop to gray mold infection in contrary to other plant-pathogen systems, where wax acts as a protective barrier. However, there is no scientific evidence to implicate it in aiding disease development, field observations and screening of 26 genotypes with different wax levels under controlled conditions in glass house and poly house showed that genotypes with high wax intensities showed higher disease severity (~60-80%) compared to low or no wax genotypes (~1-15%) indicating the role of wax in susceptibility of castor to gray mold.
