Monilinia fructicola found on Vitis vinifera in Canada


Surveys were carried out in 2001/2002 on the incidence of grapevine diseases in the south of British Colombia, Canada. In 2002, a fungus resembling Monilinia fructicola (EPPO A1 list) was observed sporulating on immature grapes (Vitis vinifera cv. Pinot noir) collected from Kelowna, and later on grapes (cv. Riesling) from Summerland. There was no evidence of brown rot near the vineyard of Kelowna, but diseased stone fruits were present near the vineyard of Summerland. The fungus was identified as M. fructicola. This indicates that M. fructicola can cause decay on V. vinifera and could be confused with Botryotinia fuckeliana. M. fructicola had previously been reported from other Vitis species in Oklahoma but not on V. vinifera. The authors thought that this is the first record of M. fructicola on V. vinifera in North America.
