Wheat volunteers in Lolium perenne : effects on Gaeumannomyces graminis var. tritici carry-over and take-all

Discusses the methodology and results of a study that used a field trial to determine whether the value of perennial ryegrass (Lolium perenne) as a break crop to reduce the risk of take-all in a subsequent wheat crop was reduced by the presence of wheat volunteers that may maintain Gaeumannomyces graminis var. tritici (Ggt) concentrations in the soil. Examines the influence of volunteer numbers on the effectiveness of perennial ryegrass as a break crop.
