Abstract:

 


It is determined that Cytospora canker (Cytospora chrysosperma “Pers.â€? Fr.) was  the cause for the death of poplars bred in Çankırı Kenbağ Forest Nursery and  Central Anatolia Region. Since the disease was  seen for the first time, “restriction and assessment surveyâ€? was conducted for  determination of the infection area, infection rate and disease intensity in  Çankırı as center, Ankara  and Kırıkkale in order to prevent the infection of clean areas and take  precautions necessary. Different media (PDA-Potato Dextrose Agar, MEA-Malt  Extract Agar, Poplar Bark Extract Agar and SNA-Synthetic Nutrient Agar) were  used in order to determine the best development media of C.chrysosperma. Infection status of C.chrysosperma, its disease intensity, its hosts and relationships  with Paranthrene tabaniformis (Rott.) (Lepidoptera: Sesiidae) were determined. A  significant correlation between C . chrysosperma and P. tabaniformis was determined  after survey data.
  The pathogen made spor  secretions which in 2-3 cm  length, reddish color, curly filamentous found on pycnidia on oily-grey  necrosis in infected poplar trunks from the end of March. Spores of the disease  agent are hyaline, single celled, in shape of slightly hunchbacked bow and average dimensions are determined as 2.5-5.0 x  0.5-1.5 µm. As a result of the studies  carried out, the pathogen was determined to develop in PDA, MEA and Poplar-Bark Extract Agar nourishing media. At the end of 21-day incubation  period, average necrosis dimensions were determined as 3.06x1.73 cm. The  infection rates due to C. chrysosperma were found as 15.77%, 14.10% and 9.28% in Çankırı (Center), Ankara and  Kırıkkale respectively. Correlations between the disease and P. tabaniformis were 0.5955, 0.6763 and 0.9037 in Ankara,  Kırıkkale and Çankırı respectively. In literature, there are certain sources  that relate the spread of C. chrysosperma with boring insects, there was not any that specify P. tabaniformis directly. However, the correlation rates in 3  cities a powerful (r>0.50) and significant (p<0.05) relationship between C. chrysosperma and P. tabaniformis. As a result it is determined that P. tabaniformis had an effect on  distribution of the disease for the first time.
