Acibenzolar-S-methyl is a fungicide that induces systemic acquired resistance (SAR) in a variety of plants leading to infection resistance. It induces resistance in wheat concomitant with expression of wheat chemically-induced (WCI) genes when applied at 30 g per hectare. Acibenzolar-S-methyl (0.4 g/L) is protective against V. inaequalis in apple trees when used in combination with light integrated pest management (IPM) and increases fruit yield in comparison to the IPM-only group.
