In summary, the cell-free filtrate and methanol extract of the cellfree
filtrate of X. nematophila TB culture are of strong inhibitory
effect on the plant pathogens B. cinerea and P. capsici both in vitro
and in planta. X. nematophila TB culture has the great potential for
controlling grey mold in tomato and leaf scorch in pepper and can be
used in the integrated control of these pathogens with the objective of
reducing the amount and number of chemical fungicide applications.
