Hale Gunacti, Ali Erkılıç


The ultimate purpose of this study was to control Potato Wart Disease. Thus, during 2010 – 2011, in order to control the Potato Wart Disease caused by Synchytrium endobioticum the efficacy of seed fungicides and soil fumigants, the influence of 15 different plants used as alternative cropping to potato and the extracts derived from carrot, onion, garlic and radish were examined on the sporangium viability. The results revealed that the roots of turnip tuber were the most effective treatment among four different plant extracts used. Sunflower and Rye were found to be promising alternative crops to potato for the region with 74% and 73% of sporangium mortality, respectively. The most effective fumigant application on the viability of Synchytrium endobioticum sporangia in the soil was Formaldehyde with a 93.8 – 97.5 % efficacy rate. The fungicide efficacy on the diseases occurrence changed from 25.2 % to 62.5 % comparing to control plots. Although significant differences were obtained numerically between efficacy ratios, no statistically significant differences were found in all applications. The most effective application on Potato Wart Disease occurrence was the dosages of 60 and 80 g /m2 of Metham Sodium among the four different concentrations of Formaldehyde, Metham Sodium, Dazomet and Urea as plant fertilizer.
