The potential for biological control of the weedy grass, Nassella trichotoma, in Australia is discussed in the light of recent surveys for pathogens in its native range and an improved understanding of the taxonomic relationships of Nassella to other Australian and South American genera of the tribe Stipeae. This information gives increased optimism that a suitable biological control agent or agents can be found. The type of research required to do this is briefly discussed.
