Diplodia natalensis, Pole Evans: a causal agent of citrus gummosis disease in Ghana

M. K. Assuah, K. A. Oduro, K. G. Ofosu-Budu

Abstract




Isolations were made from the barks of gummosis-infected citrus trees from orchards of the University of Ghana Agricultural Research Station at Kade. The isolation media used were 1.5% water agar, 1.5% water agar + nystatin and 1.5% water agar + benomyl. Four isolates including Diplodia natalensis Pole Evans, Fusarium solani Appel + Wr. and two other unidentified fungi were obtained. When the isolates were tested for pathogenicity, only D. natalensis induced the disease symptoms in the inoculated seedlings. This result strongly suggests that D. natalensis is one of the pathogens causing citrus gummosis disease in Ghana.
