Head smut, caused by Sphacelotheca reiliana, was significantly reduced by propiconazole when applied as granules in the furrow or as a surface band. Carboxin seed treatment and propiconazole as a foliar spray failed to provide significant disease reduction in trials done in 1981 and 1982. Inoculation with teliospore-infested soil applied to kernels at planting was an effective method for evaluating chemical treatments in the field.
