Effect of foliar applications Bacillus licheniformis culture filtrate on the growth parameters of potato plants infected with AMV at 70 days post inoculation. T1 = Mock-treated plants (Control), T2 = plants inoculated with AMV only, T3 = plants treated with CF 24 h before inoculation of AMV, and T4 = plant treated with CF, 24 h before inoculation of AMV and 24 h after inoculation with AMV. *Values of each column followed by the same letter are not significantly different according to the least significant differences (LSD) test (P ≤ 0.05), each value represents the mean of five replicates ± SD.
