Fusarium graminearum causing stub dieback of carnations in New Zealand

Abstract

Fusarium graminearum Schwabe was consistently isolated from stub dieback lesions on carnations in the Auckland region of New Zealand. Fusarium stem rots of carnation are also caused by F. culmorum (W.G. Smith) Sacc. and F. avenaceum (Ft.) Sacc. in New Zealand. Pathogenicity of F. graminearum isolates to carnation was confirmed.
