Effect of poultry manure and sawdust on survival of sclerotia of Macrophomina phaseolina in soil

Using wet sieving and dilution technique, the sclerotial population of Macrophomina phaseolina in soil amended with poultry manure and sawdust was studied. Sclerotial population of M. phaseolina declined after 15-day period where poultry manure @ 1, 3 and 5%w/w was used. No significant change in sclerotial population was observed where sawdust was used.
