Control take-all and gain other benefits of eliminating grass from ley pastures by chemical manipulation

Take-all is the most serious root disease of wheat and barley in Western Australia. The fungus which causes take-all (Gaeumannomyces graminis var tritici) is wide spread throughout the wheatbelt but is most common in the high and medium rainfall regions (400mm to 750mm average annual rainfall, see map). Elsewhere in the wheatbelt the presence of take-all affected cereal plants and the loss of crop yield may go unnoticed unless the roots of cereal plants are examined in detail
