Abstract
The effects of two fungicides, benomyl and triadimefon, applied at seeding, on the incidence and severity of take‐all (Gaeumannomyces graminis var. tritici) of wheat were investigated in the glasshouse and in the field. In glasshouse studies with an artificially inoculated and naturally infested sandy loam, both fungicides caused significantly less disease, whereas in a field study with a clay soil and artificial inoculum, triadimefon caused significantly less disease. In the field, both fungicides were more effective when placed near the seed as granules or as pellets than when applied as seed treatments.
