| Abstract | ||
| This study was conducted to estimate the activity of tomato debris on growth and sporelation of Al-Tahadi and Australian isolates of Trichoderma harzianum and pathogenic fungus Fusarium oxysporium f.sp.lycopersici . The study showed the concentration 30% of sterilized extract of Tomato debris by using the Millipore filter (0.22mm) was the highest effect on growth of Al-Tahadi and Australian isolates of T. harizanum and Fusarium oxysporium f.sp.lycopersici whereas the average of the growth colony diameter after 72 hour was 4.7 ,4.5 and 3.4 cm respectively compared by 8.5,8.5 and 6.5 cm with the growth on P.D.A. only respectively. Results showed also that the concentration 30 % of sterilized extracts tomato debris with Millipore filter decreased the spore germaination to 0.3, 0.2 and 0.04 ×106 CFU in Al- Tahdi and Australinan isolates of T. harizanium and F. oxysporium f.sp.lycopersici after 72 hour of growth respectively compared with 1.02 ,0.92 and 0.33×104 CFU the control treatment respectively. ....................................... . | ||
