First report of Aphanomyces cochlioides causing root rot of sugar beet in Turkey.

Abstract

Fungal root rots of sugar beet (Beta vulgaris) have been reported in various areas of Turkey but the prevalence of root rot in Konya province has not been investigated. Along with root rot pathogens such as Pythium spp. and Rhizoctonia solani, symptoms resembling those caused by Aphanomyces cochlioides including blackening at root tips of seedlings and blackish discolorations on late-stage roots were observed. Based on the symptoms, morphological characteristics, host specificity and pathogenicity, the pathogen was identified as A. cochlioides. This is thought to be the first report of A. cochlioides in Turkey.
