  1. aFour leaves were treated with a liquid culture on the upper side daily for 3 days before inoculation on the 4th day on two upper leaves and two lower leaves.
  2. bValues followed by the same letter in the same column are not significantly different using Fisher’s least significant difference test at P = 0.05.
