A survey of several management factors in an area densely populated with greenhouses in southwestern Ontario showed that few of the factors had a significant effect on the number of tomato crops affected by Fusarium foot and root rot caused by Fusarium oxysporum f. sp. radicis-lycopersici. No fully effective control measures could be identified, but it is recommended that soil fumigation or partial sterilization would be preferable to total sterilization by steam; that irrigation should be by warm water; that planting should be done in warm soil, either artificially warmed or late planted; and that mulching should be delayed to permit insolation. The incidence of the disease increased in the area since it was first seen in 1974. In 1978, 62% of the crops were affected.
