The viability of sclerotia of Macrophomina phaseolina was tested in both wet and dry soil under simulated elevated temperatures in either constant, cyclic or short temperature regimes. In wet soil viability was reduced to zero by a constant temperature of 55oC and above for 1 day or a minimum oven temperature of 50oC for 3 days. Viability of sclerotia was destroyed by a 2h temperature cycle for 7 days at 60o or 14 days at 55oC up to 11% sclerotia remained viable after 21 days. In dry soil at 60oC, a 7-day constant temperature or a 21 days 2h temperature cycle reduced sclerotial viability by 88 and 76%, respectively. Data on time and temperature relationships on loss in viability of sclerotia in soil can be used to predict efficacy of soil solarization. |
