MOA Table

Different MOA numbers define different modes of action.  Sub-groups (letters) represent distinct structural classes believed to have the same mode of action, but risk of cross-resistance may be reduced.  In rotation programs, materials with different MOA numerals should be chosen.  If none are available, chemicals from different subgroups should be chosen as an alternative to using the same compound repeatedly.
