Effect of Xenorhabdusnematophila TB culture on leaf scorch in pepper plants caused by Phytophthora capsici.

For both therapeutic and protective effect, the treatments are methanol-extracted bioactive compounds (methanol extract) at 250, 500 and 1000 μg/mL, cell-free filtrate and chemical control (25% Metalaxyl, 500×). Data are presented as Mean ± SE (n = 6). Different lower case letters above the bars indicate significant differences at P = 0.05. Different capital letters above the bars indicate significant differences at P = 0.01.
