The number of recoveries of Macrophomina phaseolina (M.phaseoli, Rhizoctonia bataticola) from infected soybean stem pieces, which were mixedin either of two soil types, decreased with increasing soil moisture from 20 to 100% moisture-holding capacities (MHC). The fungus was not recovered from stem pieces at 100% MHC for 4 weeks in either soil type.The number of recoveries from stem pieces in soils with high carbon: nitrogen (C:N) ratio amendments (40 and 80) were less than those of lowC:N ratio amendments (10 and 20). Reduction in the number of viable sclerotia may be brought about in the field by keeping soil moisture above 60% of its MHC at 30oC or above for 3 to 4 weeks. |
