Rotation may help to reduce overwintering inoculum although the soil-borne phase of the disease is of relatively minor importance.
Chemical control measures against stem-base Fusarium are rarely specifically
needed in the growing crop. Some fungicides applied for the control of other
diseases (eg prothioconazole or boscalid) can reduce the level of Fusarium
in a crop. Controlling the symptoms of Fusarium in a crop may not result
in any yield response. The main disease threat is from infected seed. Hence,
seed treatment is the main method of controlling the seedling
blight phase of the disease.
See HGCA Wheat seed health and seed-borne diseases - a guide, for more information.
