Pathogenic microflora of Syringa l. plants
Journal Title: Біоресурси і природокористування [Biological Resources and Nature Management] - Year 2019, Vol 11, Issue 1
Abstract
During the research period (2015–2018), found parasitism of 9 micromycetes species on lilac plants. The most widespread (frequency of occurrence 81.3 %) was species Microsphaera syringae (Schwein.). Frequency of occurrence of the micromycetes Alternaria alternata (Fr.) Keissl. was 22.0 %, Cladosporium herbarum (Pers.) Link. – 12.3 %, Botrytis cinerea Pers. (Botryotinia fuckeliana (de Bary) Whetzel.) – 8.5 %, Phyllactinia suffulta Sacc. f. syringae Jacz. – 8.3 %, Phyllosticta syringae West. – 4.5 %, Ascochyta syringae Bres. – 3.3 %, Cercospora lilacis (Desm.) Sacc. – 2.3 % and Septoria syringae Sacc. et. Speg. – 1.0 %. It was established that during the bloom period on lilac flowers and leaves gray mold has spreading, which further does not develop in the summer vegetation period. Powdery mildew may appear from the middle of May and intensively appears on plants during the summer-autumn period. Phyllosticta leaf spot develops from the third decade of May. Other spots (septoria leaf spot, ascochyta blight, cercospora blight) appear on plants in the summer period. Alternaria blight and cladosporium leaf spot progress at the end of the summer and in the autumn periods. The parasitism on the lilac of found micromycetes leads to a decrease in the decorative properties of plants and a gradual loss of viability.
