Use is described of a theoretical model to predict the extent of growth of the soil-borne wheat root pathogen Gaeumannomyces graminis var. tritici over a range of soil water contents. Degree of soil pore saturation (or percentage water-filled pores, % WFP) is presented as a measure of soil water con...
