Bio cont –T (W.P ) a formula of Trichoderma harzianum (T.h) was applied with soil drenching at a rate of 10g/L., and 10 ml/kg peat-mix (p.m)used to induce suppression of damping-off on radish .
Container media infested with R.
solani and non-sterilized soil mixture at 0.5% (5g/kg p.m) before incubation in dark at 24 0C for 7 ,14 ,and 28 days, then radish seeds planted(10 per pot).
Disease severity was computed after 14 days, and radish seeds were replanted again in the same treatments, subsequently disease rating was also assessed.
Disease severity in the first planting reduced to 0.11 and 0.10 in T.h amended p.m when incubated for 14 days with and with no pathogenic inoculum, respectively compared to 0.48 in control .
However, the impact of incubation periods on the efficiency of T.h was non- significant in spite of absence R.
solani inoculum.
In the second planting, full healthy seedlings were resulted in (p.m + T.h ) incubated for 28 days .In the same treatment disease rating was 0.1 when incubated for 7 or 14 days compared to 0.46 and 0.41 in the control treatments.
Apparently, isolates of examined thermophiles fungi significantly (p≤ 0.05) reduced the efficiency of T.h in the suppression of pre and post emergence damping off , since the disease occurred with 45.09 - 64.7 % for plants grown in p.m inoculated with T.h + thermophiles fungi of Rhizopus stolonifer and Aspergillus niger, respectively compared to 23-52% in the control (R.
solani + T.h).
The latter reducted disease severity to 0.1 from that of 0.21 and 0.33 when inoculated with each of R.
stolonifer or A.
niger , respectively
