520 _aThe population of bacteria, fungi and actinomycetes in fifteen rubber growing soils was estimated. The occurrence of actinomycetes antagonistic to Phytophthora meadii (McRae) and the extent of inhibitory activity were studied. In general, the population of bacteria was more than that of both fungi and actinomycetes and they varied widely in different soil samples. All soil smaples, irrespective of the pH and microbial population, harboured actinomycetes antagonistic to P. meadii and majority of these isolates had inhibition zones upto 15 mm when tested by cross steak assay. Inspite of the presence of such large number of actinomycetes antagonistic to P. meadii, various diseases caused by this pathogen reoccurred every year.
