The fate of a rifanpicin tolerant mutant (strain Rif-482) of Xanthomonas campestris pv. poae JT-P482 in soil and the effect of strain Rif-482 on soil microorganisms were examined. Two mascarene grass turf fields were used as test fields, one of which had clay soil and the other had sandy loam soil, and each soil was used in pot tests in an incubator. In sterile sandy loam soil the population of strain Rif-482 rapidly declined from over 1.0×10⁶ colony forming unit (cfu)/g dry soil to the detection limit (1.0×10³cfu/g dry soil) 3 days after incubation. However, about 1.0×10⁶cfu/g dry soil of strain Rif-482 existed in sterile clay soil 3 weeks after incubation. In the case of nonsterile conditions in pots and in the mascarene grass turf fields, the population of strain Rif-482 in both kinds of soil rapidly declined. The number of soil bacteria and soil fungi in the two mascarene grass turf fields did not change drastically after application of strain Rif-482. Strain Rif-482 and the wild type (JT-P482) showed no antagonistic activity to several microorganisms on potato semi-synthetic agar plate in a dual culture. These results suggest that X. c. pv. poae is neither able to persist nor to grow over the detection limit in soil in the natural ecosystem, and that X. c. pv. poae shows little effect on soil microorganisms.
