Effect of temperature, moisture, soil type and Trichoderma species on the

摘要: The survival of Fusarium pseudograminearum (Fp) in wheat straw was reduced significantly (P<0.05) when the sprayed with spores isolate BM1 Trichoderma koningii (Tk), incorporated into an acid red duplex soil and incubated for 4 months at two temperatures (15°C 25°C) three water potentials (−0.03 MPa. −0.3 MPa < −50 MPa). greater reduction pathogen moist (−0.3 MPa) compared wet both associated colonisation by Tk. After 6 25°C soil, completely eliminated from pieces replaced In air-dry (< MPa), Fp survived 100% even after either temperature. When infested seven antagonistic isolates spp. alkaline black earth or generally earth. However, another Tk (TW3) a T. harzianum (Th) (TW7) to low levels (3–30%) 3 30°C soils. results suggest that it may be possible, least summer-dominant rainfall are as Australia, species reduce substantially inoculum during 6-month fallow period.
