Abstract Eyespot in winter wheat is an important disease in the Netherlands. Symptoms can be found in almost every wheat crop. Italian ryegrass was shown to be a host crop and is able to maintain a high level of inoculum in the soil. In rotations with winter wheat every other year, ploughing compared with cultivating the soil in autumn resulted in a lower incidence of eyespot and a higher yield in the following wheat crop. A system of predicting the incidence at the beginning of May in order to indicate the necessity of chemical control is outlined.
