SUMMARY A series of thiocarbamoylthionitroparaffins of the general formula XC(S)SCH(CCl 3 )CH R NO 2 (where X is a secondary amino grouping and R is hydrogen or methyl), together with other related compounds, were prepared and examined for their ability to inhibit the germination of spores of Botrytis cinerea in vitro. Some of these compounds were notably fungistatic and the two most active were selected for further examination in tests against six other fungi. Their protectant fungicidal activity was also assessed against B. fabae and Uromyces fabae on broad bean and against Erysiphe graminis on wheat and compared with that of two established commercial fungicides. They were found to possess low phytotoxicity and good fungicidal properties and may find specific uses in crop protection.
