Control
Because the fungus is present within the seed
coat, rather than as a superficial contaminant
on the seed surface, seed-borne infection is not easily controlled by surface-acting
fungicides. Despite this, organomercury used to give acceptable control.
All of the currently recommended seed treatment fungicides are effective.
While seed treatment greatly reduces the risks of seedling
blight it will not afford adequate protection against later invasion
by Fusarium species present in the soil.
See HGCA Wheat seed health and seed-borne diseases - a guide, for more information.
