| The study aimed to evaluate the activity 0f the allelopathic exudates ofanise (Pimpinella anisum)،pea (Pisum sativum)،garlic(Allium sativum)and onion(Allium cepa) plants،in the growth and Pathogenicty ofFusarium oxysporium f.sp lycopersici (F.o.l.) and the ability of Trichoderma harzianum (T.h.) as a bioagent in the control and the activity of the extraction ofshoot and root ofanise and garlic plants on The growth and sporulation ofthos two fungi. The pathogenicity test of F.o.l. showed the seed decay oftomato was 100% compared with 0.0% in the T.h. treatment .The results appeared the root exudates ofanise and garlic reduced the radial growth of F.o.l. to 0.49 and 1.01 cm respeetively ،whereas the pes treatment promoted the growth of F.o.l. to 1.83 cm compared with 1.50 and 1.51 cm in control treatment ’ while the root exudates ofgarlic increased the radial growth of T.h. to 1.12 cm compared with 1.02 cm in the control. The root exudates of 50 seed ofanise and 50 gorlic bulb reduced the soft biomass weight of F.o.l. to 16.60 and 16.05 gm compared with 18.88 and 18.45 gm in the control respectively ،whereas the above treatment increased the weights in T.h. to 8.89 and 7.79 gm compared with 7.10 and 6.23 gm in the control. The root exudates ofanise plnt for growing 10 d increased the shoot length oftomato to 12.67 cm comeared with 8.8 cm in the control and root to 9.43 cm for 15 d in above treatment compared with 7.00 cm in the control increased the followring setting to 92.70 % and The in teraction’ increased The productivity to 9.72 and 9.16 kg in anise and garlic treatments respectively compared with 7.83 kg in tomato plant alone. | ||
