This study sought to determine the prevalence and crop sequence associations of Gaeumannomyces graminis var. avenae (Gga) in cereal cropping fields in New Zealand. Gaeumannomyces graminis var. tritici (Ggt) and Gga cause the root disease take-all on wheat (Triticum aestivum) and barley (Hordeum vulgare). Gga also causes take-all on oats (Avena sativa) and, when present, oats cannot be used as a break crop to manage the risk of take-all in cereals. The study used DNA assays for Gga and Ggt to… CONTINUE READING
