Özet
Bu çalışmada, Fusarium culmorum’un tarla koşullarında fungisitlere maruziyeti sonucu triticonazole+pyraclostrobin, prothioconazole+tebuconazole etkili maddeli fungisitlere duyarlılığı ve F. culmorum ile enfekteli F-85 buğday tohumlarına triticonazole+pyraclostrobin, prothioconazole+tebuconazole uygulamasının fide gelişimi üzerine etkisi tespit edilmiştir. Fusarium culmorum’un tarla koşullarında fungisit maruziyeti sonrası EC50 (?g/ml) değerlerinin değiştiği ve prothioconazole+tebuconazole için EC50 (?g/ml) değerlerinin triticonazole+pyraclostrobin’e göre daha fazla dalgalanma gösterdiği tespit edilmiştir. Fungisitlerin patojenin spor verimi üzerine etkisi olmadığı ancak, spor yapısında bozulmalara neden olduğu tespit edilmiştir. Tohumda triticonazole+pyraclostrobin uygulamasının prothioconazole+tebuconazole göre daha etkili olduğu ve tohumun çimlenme oranında önemli (P<0.05) bir artışa, hastalık şiddetin de ise önemli (P<0.05) bir düşüşe neden olduğu tespit edilmiştir.
The sensitivity of Fusarium culmorum to the triticonazole+pyraclostrobin, prothioconazole+tebuconazole fungicides following the fungicide applications under field conditions were determined in this study. In addition the effect of triticonazole+pyraclostrobin, prothioconazole+tebuconazole application to F-85 wheat seeds ınfected with F. culmorum was assessed at seedling stage.The EC50 (?g/ml) values were changed after the exposure to the fungicide. It was noted that the EC50 (?g/ml) levels of prothioconazole+tebuconazole displayed more fluctuations compared to the triticonazole+pyraclostrobin. Fungicides had no effects on the spore productivity of the pathogen, however, they caused degenerations in the spore structure. The triticonazole+pyraclostrobin application to seed was more effective than prothioconazole+tebuconazole and led to the increased rates of germination of seed significantly (P<0.05) after fungicide application and to a significant (P<0.05) decrease in the disease severity.
