Abstract
An evaluation on the effect of two tomato varieties, MT 11 and Pearl, treated with combination of two strains of
Pseudomonas putida, Ca (NO3)2 and With/without
Stonier's medium, on the incidence of bacterial Wilt,
was carried out in the field. Tomato seeds were bio-primed
with combined strains of antagonist, KTS 26
and AC1. Four-week old seedlings were transplanted
to the field, which were artificially infested with the
pathogen, to ensure even and high inoculum density.
Application of Ca (NO3)2 were done at regular intervals
before and after transplanting. Stonier's medium was
applied 4 days before transplanting. For each variety,
non-treated plants served as control. Results showed
that the antagonist and Ca (NO3)2 treatments were not
able to provide any resistance to the susceptible Pearl
tomato variety which, recorded 100% infection
