Fire blight, caused by the bacterial pathogen Erwinia amylovora, is a severe bacterial disease of apple and pear that can quickly destroy whole plants. In the last decade, it was also detected in Central Asia, where wild pomaceous fruit plants represent the dominant species in mid-altitude forests and constitute a critical foundation for the entire ecosystem. Efficiently informing farmers, forestry services and private persons about the instances and dangers of fire blight, the correct way to recognize the symptoms, and the methods of disease control is thus of paramount importance in a vast and fragmented natural landscape like the . . . one characterizing countries like Kyrgyzstan, Kazakhstan and Tajikistan. For that purpose, we have developed an app for smartphones and mobile devices that can inform stakeholders about fire blight, simultaneously allowing a citizen science approach for mapping the spread of the disease in Central Asia. The app is available in the three national languages as well as in Russian, English, and German, and can easily be adapted to new countries, languages or even diseases.

During June and August in 2018, kiwifruit (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?n three commercial orchards located in Altınordu, Fatsa and Perşembe districts of Ordu province. After surface sterilization with 1?aClO, small pieces excised from root tissues of diseased plants were rinsed twice in sterile distilled water, dried on sterile filter papers and aseptically transferred to plates containing potato dextrose agar. Ten isolates from the plates were identified as Macrophomina phaseolina (Tassi) Goi . . .d. based on the growth characteristics, agar pigmentation, and the presence of microsclerotia 78.8 to 90.75 μm in diameter (n = 30) (Dhingra and Sinclair 1973). To confirm the identification, the internal transcribed spacer (ITS) of rDNA of a representative isolate (KWF09) was amplified and sequenced. The resulting 537-bp sequence (GenBank accession No. MK287619) shared 99?imilarity to those of M. phaseolina isolates CBS-231.33, CBS-457.70 and CBS-126630 (KF951631, KF951636 and MH864176, respectively) in the GenBank database. The pathogenicity assay with isolate KWF09 was performed on 4-month-old kiwifruit seedlings according to Singleton et al. (1993). The seedlings were transferred to the growth chamber and kept at 28 °C. Six weeks after inoculation, brown to black lesions were observed on the roots of inoculated plants, from which M. phaseolina was consistently re-isolated. Although detailed studies are needed to determine the distribution of charcoal rot in Ordu, to our knowledge, this is the first report of charcoal rot caused by M. phaseolina on kiwifruit from Turkey More less
