The potential increase and spread of Fusarium head blight (FHB) in the western Prairies is of concern to the cereal industry. It is important to determine if planting infected seed may introduce F. graminearum (Fg) into a field. A greenhouse study was conducted to assess the effectiveness of chemical seed treatments (ST) in preventing the spread of Fg from infected common wheat (Triticum aestivum L.) seed to plant tissue. Fg-infected seed treated with each of seven ST were planted in a soil-less mix. Controls consisted of untreated infected seed, and seed from an uninfected lot. There were six seeds per treatment, and five replications. The test was conducted twice. The untreated infected treatment had a lower number of seedlings emerged and plants alive at harvest than most of the ST. Discoloration of subcrown internodes, crowns, and stems was observed in all treatments, whereas Fg was isolated only from the infected treatments. None of the ST reduced the transmission of Fg to under- or above-ground tissue of live plants. Maximum transmission of Fg to plant tissue was less than 10%.
