A phytotoxic compound was isolated from a culture of Bipolaris cynodontis, a fungus pathogenic to Bermuda grass. The structure was determined by spectroscopic analyses including 2D NMR experiments, to be sesquiterpene having a 9-carbon unit side chain. The compound inhibits the root growth of the seedlings of Italian ryegrass and rice plant, the host plant of the B. cynodontis, by about 100% at 100ppm, and it is suggested that this may play an important role in the expression of the disease symptom.
