In: Assiut Journal of Agricultural Sciences 2007.v.38(2)Summary: The effect of different concentrations of salicylic acid (SA) or oxalic accd (OA) on linear growth of Fumarium oxysporum f. sp. lycopersici, the causal agent of tomato wilt was studied in vitro. SA concentrations ranging from 750 to 2000 ppm have significantly reduced mycelial growth of the pathogen. While, OA significantly inhibited the linear growth at concentrations ranged from 500 to 2000 ppm. The percentage of inhibition varied between the three tested isolates of F. oxysporurn f. sp. Iyeapersici , the highest inhibition was occurred in FOL isolate 4.
