Abstract
The introduction of Gaeumannomyces graminis var. tritici (Ggt) inoculum into soils to screen for take-all suppression has been widely used in field and laboratory studies. However, the amounts of Ggt inoculum reported have varied greatly. The effects of adding Ggt in sand/maizemeal to three soils of different cropping history at the rates of 0, 0.2, 0.5, 1 and 4 % (w/w) were investigated in a pot assay using wheat plants. The three soils had previously been cropped with ryegrass for 5 years, wheat for 8 years, and wheat for 2 years. The soils represented a putative non-suppressive, non-wheat soil; a suppressive wheat soil; and a non-suppressive wheat soil, each containing natural background concentrations of Ggt DNA of 0, 200 and 1126 pg g−1 soil, respectively. Root assessments of wheat plants after 4 weeks growth showed that 4 % of Ggt reduced root growth slightly, decreased water uptake of the wheat plants and effectively differentiated the suppressive activity of the soils (P < 0.01, take-all incidences of 83, 69 and 81 %, respectively), and was therefore suitable for investigating take-all suppression in soils.
