SUMMARY In a glasshouse pot experiment two successive wheat crops were grown to near maturity in soils naturally infested by the take‐all fungus, Gaeumannomyces graminis var. tritici , with or without inoculum of Phialophora radicicola var. graminicola (PRG) added before the first crop was sown. PRG decreased take‐all in both crops. More PRG infections were recorded on plants in soil taken from continuous wheat than in soil from a second wheat crop or beans. Field plants were also more infected by PRG in continuous wheat than in first, second or fourth wheat crops after beans, but fewer root pieces were infected than on plants from pots. Evidence to suggest that PRG may contribute to the decline of take‐all in continuous wheat was inconclusive. No PRG was recorded on Alopecurus myosuroides.
