Exudates from germinating seed of P. resinosa stimulated the germination of sporangia and increased the Pythium populations in soil. Sporangia of P. irregulare did not germinate in natural soil and needed exogenous nutrition for their germination. Different components of the exudate, particularly glucose and asparagine, effectively stimulated sporangial germination. This is in agreement with an earlier finding with Pytl1ium ultimum 3.
