| * | Registration pending in California. Section 18 emergency exemption approved for February 1 to April 15 2026. |
| ** | Not registered, label withdrawn or inactive in California. |
| 1 | Alphabetically arranged organic treatments. Note that kasugamycin is a fermentation (natural) product, but not an organic treatment. |
| 2 | FRAC group numbers are also provided as BM- or P-number codes (NC = not coded in FRAC). 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 | Sodium lauryl sulfate is not organically approved for crop production (synthetic substance approved for noncrop areas); All Phase is not organic. Cinnacure, PlantShield and Vintec do not have OMRI/WSDA certification and do not claim to be compliant, but their active ingredients are allowed for organic production. |
| 4 | Alternaria leaf spot caused by Alternaria alternata and A. arborescens. |
| 5 | Hull rot ratings are for the disease caused by Rhizopus stolonifer. |
| 6 | PM refers to a powdery mildew disease. |
| 7 | Labeled for Eutypa sp., Botryosphaeria sp., Cytospora sp., and other trunk diseases of almond. |
