Take-all disease of wheat is caused by the soilborne fungus Gaeumannomyces graminis var. tritici (Ggt). This disease infects the roots, crown, and basal stem of plants. Take-all is common in western Oregon whenever consecutive crops of wheat are grown. Grain yield may be reduced by as much as 50 percent in second or third crops of winter wheat. In extreme situations, wheat plants may be killed; hence the name “take-all”.
