  1. Values are the means of three replicates
  2. Means within the same column and treatment followed by the same letter are not significantly different according to Duncan (P ≤ 0.05)
  3. NPs conc.* = NPs concentration
  4. Nano-control** = The best concentration recorded the lowest of infection rate and non-toxic to the plants
