Mould board ploughing, long the foundation of arable agriculture, has been replaced on many British farms by reduced cultivation systems not involving the inversion of the soil. There is also an increasing interest in direct drilling into untilled soil. The change to such techniques may be expected to influence the incidence of certain cereal diseases. Increases in Rhynchosporium secalis (Oud.) Davis and Septoria spp. have been noted in non‐plough situations where infected debris is left on the soil surface. Effects on other diseases are more complex and may be mediated through the effects of cultivation technique on time of sowing, crop establishment, weed control, pest incidence and other factors including the physical nutritional and microbiological characteristics of the soil.
