The possible reasons for this phenomenon were decreasing activities of superoxide disumutase, inhibiting glutathione reductase activities and increasing ascorbic acid peroxidase activities by the pathogen. It suggested that scavenge of harmful products from sulfur dioxide was inhibited by the infection of A. brassicicola.
