SUMMARY The effect of cultivations on the spread of Gaeumannomyces graminis var. tritici from a line source of inoculum, consisting of naturally infected stubble and roots, was recorded in the field over 2 yr. With the aid of cultivations, spread in the first wheat crop occurred frequently to a distance of 0·9 m and occasionally to a distance of 2·5 m. However, the following wheat crop was uniformly infected, probably as a result of a rapid build‐up of background inoculum in the first wheat, so that any spread by cultivations was masked.
