1 Alphabetically arranged by biological or natural product name.
2  FRAC groups are also provided as BM- or P-number groups. In general, sulfur compounds are fungicidal and may affect applications of fungal biocontrols (e.g., Botector); whereas copper may affect applications of bacterial biocontrols (e.g., Actinovate, Double Nickel 55, and Serenade). Rotations must consider these factors.
3 PM = powdery mildew.
