PROBLEM TO BE SOLVED: To provide an agent for controlling the disease injury of a plant of the family Cruciferae, having high controlling effect on clubroot which is the disease of a plant of the family Cruciferae and free from environmental contamination and provide a method for the control of the disease injury. SOLUTION: The plant disease injury is controlled by contacting a plant of the family Cruciferae with a controlling agent containing CGF4526 strain of bacteria of the genus Variovorax having antagonistic property against the clubroot of a plant of the family Cruciferae. The controlling agent is mixed in the raising seedling soil in sowing or irrigated to the seed before or after sowing. It may be used by immersing the root of a seedling in a diluted solution of the agent before the fix planting or irrigating to a seedling during the raising seedling period or immediately before fix planting. The clubroot disease of plants of the family Cruciferae such as Chinese cabbage, cabbage, cauliflower and broccoli can be strongly controlled without causing the environmental contamination problem.
