First report of charcoal rot caused by Macrophomina phaseolina on kiwifruit in Turkey.
During June and August in 2018, kiwifruit (Actinidia deliciosa cv. Hayward) plants exhibiting symptoms of charcoal rot including chlorosis, necrosis, leaf shedding, root rot, and trunk dry rot were observed with an incidence of up 5% in three commercial orchards located in Altınordu, Fatsa and Perşembe districts of Ordu province, Turkey. Based on growth characteristics, agar pigmentation, presence of microsclerotia 78.8 to 90.75 μm in diameter (n=30), sequence analysis of the rDNA internal transcribed spacer and pathogenicity assay, the causal agent was identified as Macrophomina phaseolina. This is thought to be the first report of charcoal rot caused by M. phaseolina on kiwifruit from Turkey.
