dc.description.abstractPerennial ryegrass (Lolium perenne) is the major pasture grass in New Zealand but is highly susceptible to take-all disease, caused by the root-rot pathogen Gaeumannomyces graminis (Gg). Isolates of the fungus Trichoderma atroviride are known to control Gg but it is not known if a mixture of isolates would be more effective than individual ones. Soil from a field naturally infested with Gg was placed in containers in a glasshouse and sown with ryegrass seeds then treated with one of three Trichoderma atroviride isolates or a mixture of all three isolates. All T. atroviride treatments significantly increased shoot dry matter by 46–73% and root dry matter by 42–62% compared with the control but a mixture of isolates was no more effective than individual isolates. Application of T. atroviride also significantly decreased root disease severity, which was negatively correlated with root dry matter. Take-all in pastures could possibly be controlled by overdrilling grass with a single isolate of T. atroviride.en
