Table 6. Effect of Rudan PK and Rudamino Applications on the Control of Apple Scab in ‘Gala’ Apples. Santa Isabel Experimental Field, São Joaquim/SC. 2014/2015 Season
Fungicides were applied on: 09/13, 09/20, 09/27, 10/04, 10/10, 10/18, 10/25 and 10/30/2014.
Inc. = Incidence of scab on leaves (11/06/2014) and on fruits (11/11/2014).
CI = Control index of scab on leaves and fruits (%).
Means followed by at least one identical letter within the column do not differ by Duncan’s test (P = 0.05).
Conclusions
Rudan PK (200 mL/100 L) is highly effective in controlling leaf scab in apple trees, showing no statistical difference compared to phosphite 40(P)-20(K) (200 mL/100 L), which was the standard phosphite in the trial.
Rudamino (200 mL/100 L), although not statistically different from Score, showed a tendency to enhance Score’s performance in fruit scab control.
Rudan PK and Rudamino are safer alternatives, as they
