LSD (Fungalpathogens xSA concentrations) = 0.631 cm at P≤0.05.
aMean mycelial growth per fungal pathogen for allsalicylic acid concentrations combined.
b Mean mycelial growth per salicylic acid concentration for all fungal pathogens combined.
* For fungal pathogens and salicylic acid concentrations tested, values (means) followed by the same letter are not significantly different according to Duncan's Multiple Range test at P ≤0.05.
Pathogens were cultured on PDA medium and incubated at 25°C for 1 d (P. aphanidermatum), 2 d (R. solaniand S. sclerotiorum), 3 d (B. cinerea, FOL, FORL and F. solani), 4 d (A. solani and C. coccodes) and 7 d (VD). |
