Rating: 3 = most effective, 2 = moderately effective, 1 = least effective, and 0 = ineffective (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”.
