摘要

Fusarium stem canker of greenhouse eggplant, incited by Fusarium solani (teleomorph Nectria haematacocca), caused extensive losses in yield in a commercial operation in Leamington, Ontario, in 2005. Identification of the disease was based on host symptoms, reisolation of the pathogen, morphological and cultural characteristics of the fungus, and the fulfillment of Koch's Postulates. Control measures are discussed. This is the first report of this disease on greenhouse eggplant in Canada.
