Aims

To evaluate the effectiveness of fungicide seed dressings and in-furrow treatments against cercospora leaf spot in faba bean.

Key messages

Tebuconazole foliar fungicide is the superior treatment for controlling this disease, showing that Systiva® seed treatment or Uniform® in furrow were not effective fungicide treatments for control of cercospora leaf spot. 182 Infection from cercospora leaf spot was high early in the season at eight node stage where Uniform mildly suppressed severity compared to the nil treatment. However, by spring the standard tebuconazole treatment at six node growth stage prevented further spread of the disease.
