PREPARATION, BIOTRANSFORMATION, AND ANTIFUNGAL ACTIVITY OF METHYL BENZYLDITHIOCARBAMATES

The biotransformation of three methyl benzyldithiocarbamates by the bl ackleg fungus (Leptosphaeria maculans (Desm.) Ces. et de Not., asexual stage Phoma lingam (Tode ex Fr.) Desm) was investigated. The main bio transformation products were isolated and their chemical structures we re determined by spectroscopic methods. Similarly to our previous stud ies with the phytoalexin brassinin, these results suggest that virulen t blackleg isolates are significantly more effective in metabolizing b enzyldithiocarbamates than the related avirulent isolates.
