Rotation appears to have little effect on disease incidence. Late sowing may reduce disease as would ploughing infected stubble. There is evidence that winter wheat varieties differ in their resistance to sharp eyespot. However, the resistance is not particularly effective.
Azoxystrobin can give good control but the disease rarely warrants specific treatment. Boscalid, prothioconazole and prochloraz may suppress the disease but the level of control is unpredictable. Fungicide treatment is generally not cost effective.
