Abstract
Ascochyta pinodes, the causal agent of pea anthracnose, cultured on st erilized wheat, produces toxic metabolites. The main phytotoxin, named pinolidoxin, was isolated and characterized using spectral and chemic al methods as ienoyloxy)-7,8-dihydroxy-9-propyl-5-nonen-9-olide, a new phytotoxic 10-macrolide. When assayed on host (pea) and non-host (bea n) plants, pinolidoxin was highly toxic; towards brine shrimps it was only weakly toxic.
