SUMMARY Ergot ( Claviceps purpurea ) of grasses is prevalent throughout Britain. The disease also occurs regularly in most cereal varieties but generally is of low incidence. Incidence is much greater in open‐flowering and male‐sterile cereals, with the infection seeming to come, initially, from the large reservoir of inoculum amongst grasses. The production of F 1 ‐hybrid cereal seed, which necessitates the use of male‐sterile lines, could therefore be jeopardised.
