Statistical analysis
An analysis of variance was applied to the results
of each experiment. Incidence data and number of
decayed berries per kg of fruit were transformed (arcsin
of the square root of the proportion of affected fruit)
before analysis. Means were separated using Fisher’s
LSD (P≤0.05).We apply the term synergy as defined
by Richer (1987), where the effectiveness of a combination
of treatments exceeds the prediction of the effectiveness
of their additive action estimated by Limpel’s
formula (Ee = X + Y−(XY/100)).
