Populations of viable microsclerotia of Macrophomina phaseoli were studied in the soil from Flacerville, California, using the newly devised flotation method. It was found that there were some 30 viable microsclerotia/g of the nonfumigated forest nursery soil. In the soil fumigated with two fumigants, Trizone and Pathofume, the build-up of the pathogen was very slow even 3 years after fumigation, generally showing less than 6 viable microsclerotia/g of soil. Microsclerotia were recovered ata a depth of 61 cm below the soil surface even in fumigated soil. The host effect on populations of microsclerotia was very significant and twice as many microsclerotia were recovered from firplanted soil as from pine- or nomplanted areas. M. phaseoli was aso to be present as microsclerotia in both cultivated and uncultivated soils collectd from several localities in California and in Guatemala. There was a significant correlation between populations of microsclerotia and percentage of mortality of bean in both naturally and artificially infested soil under greehouse conditions. It was also demonstrated that some isolates were avirulentat the same inoculum levels which occur in nature. Preparation of microsclerotia propagules greatly influenced virulance. Tissue-formed microsclerotia are more virulent even at lower levels of inoculum tham are cultured ones. By means of the flotation method and soil plating method, it was possible to isolate the pathogen, to determine the population of viable microsclerotia in the soil, and to...
