Fumonisin B2 is a fumonisin mycotoxin produced by the fungi Fusarium verticillioides and Fusarium moniliforme.^[1] It is a structural analog of fumonisin B1. Fumonisin B2 is more cytotoxic than fumonisin B1. Fumonisin B2 inhibits sphingosine acyltransferase.

Fumonisin B2 and other fumonisins frequently contaminate maize and other crops.
