* Treatment conditions are described in Table 1.
§ Incidence was evaluated by harvesting the entire plot and calculating the number of infected fruits per 20 fruit. Severity rating was the average severity of the infected berries sampled in each plot.
ф DAA—means days after application.
¥ Means followed by the same letter do not significantly differ (P = 0.05, Duncan´s New MRT). Mean comparisons performed only when AOV Treatment P(F) is significant at mean comparison OSL.
