Nassella neesiana (Chilean needle grass), a South American species, is an intractable weed invading managed pastures and natural grasslands that has become a target for biological control in Australia and New Zealand. Studies have been carried out to assess the potential of three rusts naturally infecting this grass species in Argentina: Uromyces pencanus,(More)
Three rusts, Puccinia nassellae, Uromyces pencanus, and Puccinia graminella, are being studied as potential biological control agents for Nassella neesiana (Chilean needle grass) in Australia and New Zealand. An understanding of the life cycle of a pathogen is desirable before its release as a biocontrol agent is considered, to enable the assessment of the(More)
