The aim of this study was to investigate the effect of the fungicide Funaben T (s.a. thiuram - 45%, carbendazym - 20%) on the occurrence of various ecotrophic groups of bacteria in soil under pea cultivation. In the examined developmental stages of the pea, in the rhizospheric and non-rhizospheric soil, the counts of oligotrophic, copiotrophic, methyltrophic, amylolytic, pectinolytic, Pseudomonas, phosphate solubilizing and Azotobacter bacteria were determined using culture methods. The obtained results showed that the applied fungicide, Funaben T, did not have any major effect on the growth of most investigated groups of bacteria in the non-rhizospheric zone. However, in the rhizosphere (in the majority of cases) it stimulated the growth of the investigated groups of bacteria except for the periods of budding and flowering. In those stages the fungicide inhibited the growth of bacteria.
