摘要: Trichoderma harzianum has been found to be a competitor and mycoparasite ofFusarium verticillioides which causes foot rot disease on rice. The experiment was undertaken macroscopically microscopically. In total 6 treatments were performed combining three water activities (0.95, 0.98, 0.995) two temperatures (15 25 °C). At all conditions tested, except at 0.95a w 15 °C.Trichoderma acted as biocontrol agent trough synergistic mechanisms — competition mycoparasitism overF. verticillioides. °C mutual antagonism by contact observed. effect of abiotic factors activity temperature fungal growth determined.
