7. SUMMARY The studies on sensitivity of S. sclerotiorum isolates to some fungicides. S. sclerotiorum causes Sclerotinia rot diseases which damages seriously on several vegetables all over the world. The disease appears in all regions where Summer and Winter vegetables are grown. If Winter conditions are conducive for disease, the pathogen may cause economical losses in Aegean and Mediterranean Sea Regions of Turkey, especially. On the most of greenhause vegetables, S. sclero* tomm leads to stem rot in general. Among the control measurements, chemical control, particu larly fungicides are used unknowingly and extensively during vegetable growing period. This may give rise to some health and environmental problems, beside reducing in sensitivity of pathogen. Therefore, the success of chemical control depends on these factors. This study was carried out to determine the sensitivity level of S_. sclerotiorum isolates and to find out fungicides using strategies, to apply these using strategies in practice, and finally, in the light of this study, to give some research on this topic to be carried out in the future. The materials used in this study were 80 S_ - sclerotiornm isolates and benomyl, carbendazim, carbendazim+diethof encarb, iprodione, tolchlophos-methyl, çaptan and thiram fungicides. 55According to ED 50 values, S - sclerottornıpf isolates were found higher sensitive to carbendazim, carbendazim+diethof en- carb, iprodione and benomyl than other fungicides. According to MIC values, most of isolates showed an important variation against the fungicides. These isolates had high MIC values in general. The efficacy of suggested dosses and low dosses of fun gicides determined ED 50 and MIC values to sensitive and low sensitive Ş. sclerotlnrnm isolates were tested. While carben dazim+diethof encarb, benomyl and iprodione were found very ef fective, hexacanazole was found eff ective. However, tolchlophos- methyl, çaptan and thiram were not found effective. The effi cacy of application dosses of fungicides except for hexacana zole to sensitive and low sensitive isolates was not found different in general. As a result, while Ş. sclerotlnrnm isolates were found extremely sensitive to carbendazim, carbendazim+diethof encarb, benomyl and iprodione, they were found sensitive against hexa canazole. However, the sensitivity of S. sclerot
