Gnomoniopsis smithogilvyi : identification, characterization and incidence of the main pathogen causing brown rot in postharvest sweet chestnut fruits ( Castanea sativa ) in Chile
Australasian Plant Disease Notes(2022)
Abstract
We describe the first identification of Gnomoniopsis smithogilvyi causing brown rot on chestnut fruits in Chile, with an incidence of 4.8%. Previously, Phomopsis castanea (IMI 278057) was reported as the cause of the disease in Chile, but a molecular re-identification revealed that it corresponded to G. smithogilvyi . All chestnut fruits inoculated with the isolate G. smithogilvyi RGM 2903 developed brown rot symptoms on fruits.
