Capsidiol, the antifungal sesquiterpene induced in fruit of pepper (Capsicum frutescens L.) by fungi was demonstrated in bacterial soft rot lesions in fruit collected from the field. In laboratory experiments, Erwinia carotovora isolated from rotted fruit induced small quantities in diffusates and larger amounts in rotted tissue. Capsidiol (1 µmole/ml) was not active against the bacteria isolated and hence is not of significance in resistance to bacterial soft rot.
