Summary, etc. Zinniol was isolated from culture filtrates, mycelium and cell walls of Alternaria dauci, Its production was increased by a high carbon-nitrogen ratio and in the presence of t-asparagine or carrot leaves, as compared to nitrate. Zinniol could be detected during spore germination and early growth phases. Application of'zinniol to carrot leaves was followed by the development of dark brown necrotic spots within 1 h. The symptoms caused by zinnial were identical with those produced by the fungus. The lowest phytotoxic dose was I roM. Both the hydroxymethyl groups and the isoprenoid chain were essential for the phytotoxic activity of the zinniol molecule. The position of the 3-methyl-2-butenyl-oxy in the benzene ring was not significant for activity. [uC]zinniol was readily metabolized by carrot leaves and could not be detected in artificially infected leaves.
