T1: Mock-treated tomato plants; T2: tomato plants inoculated with TMV only; T3: tomato plants treated with P. argentea extract only and T4: tomato plants treated with P. argentea extract 24 h before TMV inoculation. Data represent the mean value from three biological replicates, and standard deviation (±SD) is shown. Data with the same letter means do not differ significantly. The significant differences were assessed using the least significant difference (LSD) at a p ≤ 0.05 level of probability.
