SUMMARY The effects of direct drilling, shallow cultivation and ploughing on the infection of winter wheat roots by the take‐all fungus ( Gaeumannomyces graminis var. tritici ) were studied on three field sites over a number of years. All three soil types were categorised by Cannell, Davies, Mackney & Pidgeon (1978) as suitable for sequential direct drilling. The results show that a smaller proportion of roots was infected at depth in the direct‐drilled plots in May/June. However by July these differences had all but disappeared and an estimate of infection in the top 7 cm of the roots (approximately equivalent to traditional hand sampling for take‐all) gave a reliable comparison of the total take‐all on plants grown under these different cultivation systems.
