Occurrence of wood-rotting fungi at a peach orchard in Yamanashi Prefecture.
We investigated the occurrence of wood-rotting fungi in a peach orchard in Yamanashi Prefecture where some peach trees died after gale damage and some other trees suffered with dieback of main or side branches. We found the fruit bodies of nine wood-rotting fungi on peach trees. Trametes versicolor, Ganoderma applanatum and Ganoderma lucidum have already been recorded as causing disease outbreaks on peach trees. The other five fungi, i.e., Fomitopsis sp., Trametes hirusuta, Oligoporus sp., Laetiporus cremeiporus and Perenniporia fraxinea are recorded for the first time on peach trees. Abortiporus biennis may not be a pathogen of peach trees. We would like to propose their disease names after further studies on pathogenicity to peach trees and other properties of those species.
