Different methods of applying triadimefon to sugarcane setts and to the soil at planting for the control of smut were tested in field trials. Immersing healthy setts in cold water containing 250 pglml triadimefon was beneficial when the setts were subsequently inoculated with smut before planting or grown under low levels of the disease, but was ineffective when smut was severe. Treating seedca...
