Abstract
A considerable bacterial and fungal populations are lived on the aerial
surfaces of tomato plants even at the age of 8 weeksTwo epiphytic bacterial strains
and two epiphytic yeast ones proved to be highly antagonistic against the tomato
pathogens (Pseudomonas syn'ngae pv. tomato and Xanthomonas campestris pv.
Vesicatorfa)in vitro studies. One of the most antagonistic bacterial strains belongs to
the genus Bacillu sand the other one belongs to the genus Pseudomonas.The two
most antagonistic yeast strains taxonomically belong to the genera Aureobasidium
and Cryptococcus.
0n the base of their in vitro antagonism, the most effective antagonistic
bacterium, i.e. Pseudomonas sp. and the most effective yeast strain, i.e.
Crxotococcus sp. were tested in pot experiments. Both the tested bacterium and the
yeast strain showed a significant antagonistic effect against Pseudomonas syringae
pv. tomato and Xanthomonas campestn's pv. vesr‘caton‘a. The preventive effect of the
two selected microbes on the bacterial speck and bacterial spot diseases was
exhibited in a preliminary pot experiment too.
