In this study, seedlings of tomato cultivar Carolina Gold were treated by garlic (G) and black pepper (BP) extracts using different application methods and inoculated with F. oxysporum f.sp. lycopersici. Immerging roots (IR) in G@4.0%, spraying shoots (SS) with G@4.0% or BP@4.0% caused 100% reduction in the incidence of tomato fusarium wilt. IR+SS/BP@4.0% induced the highest increase in plant height (40.8%) followed by IR/G@0.5% (38.7%) and IR+SS/G@0.5% (33.2%) whereas IR/G@0.5% caused the highest increase in the root length (64.5%) followed by IR/BP@0.5% (57.0%) comparing to the untreated control.
