PROBLEM TO BE SOLVED: To provide a controlling agent for plant disease injury comprising a strain having inhibitory effects on the plant disease injury even when changed into a dead fungal cell in Verticillium lecanii which loses the activity to die out in a relatively short time under environmental conditions unsuitable for survival such as high temperatures or direct sunlight, and to provide a method for controlling the plant disease injury using the controlling agent for the plant disease injury. SOLUTION: A live fungal cell, a filtrate of the live fungal cell, a dead fungal cell, a filtrate of the dead fungal cell or a culture filtrate component of the Verticillium lecanii in which dead spores after a heat treatment have an inhibitory ability in the plant disease injury is used as the controlling agent for the plant disease injury. An MG-VL-45 strain (NITE P-493) or an MG-VL-101 strain (NITE P-494) can be cited as the Verticillium lecanii in which the dead spores after the heat treatment have the inhibitory ability in the plant disease injury.
