Kerman province with 2297 hectares ha of rose gardens and 6198 tons of flower production is one of the important rose production regions. The productions of this region are organic and do not use anychemical compounds such as pesticides and fertilisers. The major fungal pathogens were studied during 2008–2010 in oil rose production areas in Kerman province, Iran. Verticillium dahlias, Rosellinia necatrix, Alternaria alternata, Seimatosporium fusisporum and Podosphaera pannosa have been detected in the oil rose from different regions in Kerman province. A. alternata has the most isolates and infected plants per cent in the oil rose.
