Abstract

Fenarimol and triadimefon caused significant (P<0.01) in hibition of linear growth of Fusarium graminearum Group 1 at 100 ppm whereas fenfuram and carboxin caused inhibition at 500 and 1000 ppm, respectively, in in vitro studies.

The use of wheat seed infected naturally with F. graminearum Group 1 resulted in infection of plants by this fungus, crown rot development and whitehead formation. Seed treatment with carboxin, fenarimol and triadimefon at rates used commercially did not affect the incidence of infected plants, whitehead formation, seedling emergence or yield.
