Note: Not all indicated timings may be necessary for disease control.
Disease | Dormant | Early bloom | Mid-bloom | Late bloom | Preharvest | Postharvest |
---|---|---|---|---|---|---|
Alternaria fruit rot (black heart) | — | +1 | + | + | — | — |
Gray mold (Botrytis fruit rot) | — | ND | ND | ND | +2 | +++ |
Rating: +++ = most effective, ++ = moderately effective, + = inconsistently effective, ---- = ineffective, and ND= no data. | |
1 | Pomegranates have a long protracted bloom, thus apply when conditions are favorable for disease (i.e., wet conditions). |
2 | Preharvest treatments are highly variable in efficacy due to difficulty in fungicide coverage into the fruit "crown". |
