Effect of Xenorhabdusnematophila TB culture on grey mold in tomato plants caused by Botrytis cinerea.
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 (50% Sumilex, 1000×). 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.
