“…The results from surveys indicated the presence of Verticillium spp. in the vascular tissue of tubers (Easton et al 1972;Platt 1986;MacGarvie and Hide 1966;Nachmias and Krikun 1984;Ebihara et al 2003;Omer et al 2000;Tsror et al 1999;Göre et al 2015). Substantial research has been conducted assessing the effect of soilborne inoculum on Verticillium wilt development (Nicot and Rouse 1987;Nagtzaam et al 1997) and recently soilborne inoculum was found to be more important than seedborne inoculum .…”

Colonization of stems, symptom development, yield, progeny tuber infection, quantification of soil inoculum and contribution of soil inoculum on subsequent disease development by Verticillium dahliae, causal agent of Verticillium wilt of potato was evaluated in the glasshouse using naturally infected and non-infected seed tubers of seven cultivars in two trials. Internal seed tuber infection of seven potato cultivars did not contribute to severe disease development although the pathogen was isolated from symptomless plants. Susceptible cultivars Atlantic, Trent and Russet Burbank had the highest incidence of petiole infection while the moderate resistant cv Ranger Russet had the lowest incidence at 65 days after planting. Progeny tuber infection in various cultivars after harvest ranged from 0 (cv Ranger Russet) to 13% (cv Atlantic). Planting infected tubers contributed to V. dahliae inoculum in the potting soil. Mean levels were highest from cv Russet Burbank (70 pg DNA/g of soil; range from 6-149) while the least was recorded in cv Ranger Russet planted soil (11 pg DNA/g of soil; range from 3-31). Soil inoculum originating from naturally infected tubers did not contribute to subsequent foliar disease development in Russet Burbank and Shepody cultivars that were grown in this infected soil. However, V. dahliae was isolated from the petiole of some symptomless plants. Progeny tubers were completely free from V. dahliae. Tubers of cv Nicola, infected with Verticillium tricorpus, produced very few Verticillium wilt symptoms but the fungus was re-isolated from the petiole of symptomless plants. Only 4% of progeny tubers were infected by the pathogen and the level of V. tricorpus inoculum in the soil at maturity was only 1 cfu/g of dry soil. There was no significant difference in the yield of tubers between plants originating from infected and non-infected tubers.

“…Numerous fungal pathogens have been implicated as causal agents of diseases and yield decline problems (Koike et al 2007). Rhizoctonia solani, Synchytrium endobioticum and Verticillium dahliae were reported as the most important soil borne fungal disease agents of potato in Turkey (Cakir 2005;Yanar et al 2005;Gore et al 2015).…”

Potato [Solanum tuberosum] is an extensively consumed vegetable in Turkey. In March 2016, typical stem rot (also known as white mould) symptoms were observed on commercially produced potato plants (cv. Rosetta) in several fields inspected in Hatay province of Turkey. White mycelium and large, irregular, black sclerotia were observed on infected stems, crowns and occasionally on leaves. Apothecia development from sclerotia were also observed on moist sand. Based on morphological characteristics of mycelia and sclerotia, all isolates were tentatively identified as Sclerotinia sclerotiorum. The identity of the fungal isolate was confirmed using MALDI-TOF MS and sequencing of the ITS rDNA region, using ITS4/ITS5 primers. To our knowledge, this is the first report of stem rot disease on potato caused by S. sclerotiorum in Turkey.
