ISOLASI BAKTERI PATOGEN Ralstonia solanacearum DARI TANAMAN CABAI RAWIT (Capsicum frutescens) DI PERTANIAN CABAI TANAH MERAH

Abstract

Ralstonia solanacearum is one of the bacteria that attacks chili plants which causes wilt disease. Chili plants attacked by R. solanacearum will be difficult to be recovered. R. solanacearum is a pathogenic bacterium which is transmitted through the soil. This bacteria is also one of the factors reducing chili yield in Indonesia. Cayenne pepper (Capsicum frutescens) in Tanah Merah chili farming is often attacked by wilt disease, so R. solanacearum isolation was carried out to identify bacterial wilt in chili farming in Tanah Merah and to obtain a collection culture so that further testing could be performed. R. solanacearum in this study was isolated from stems of the chili plant. Isolation of this bacteria using casamino acid peptone glucose medium. Then it was identified by observing the macroscopic and microscopic morphological characters. The results of this study obtained bacterial isolates with characteristics of R. solanacearum.
