Alternaria species associated with 'moldy heart' on peaches in Argentina
Moldy heart caused by alternaria spp has been previously reported in apples in argentina. However according to our knowledge this is the frst report of alternaria spp in 'moldy heart' affected peaches in this country. direct isolation of the pathogen was performed on dichloran-chlorampheni...
