| Abstract | ||
| Eight plant essential oils namely; anise, caraway, celery, coriander, cumin, dill, fennel and parsley were in vitro tested for their activities on the growth of three seed-borne fungi, Fusarium oxysporum, F. solani and Rhizoctonia solani which caused damping-off for lupine plants. Anise oil showed the highest inhibitory effect against R. solani (100%), F. oxysporum (66.12%), F. solani (52.92%) and at 4 ml/L, however, celery and caraway oils showed the least effect. Volatile substances from anise oil were completely inhibited mycelial growth of fungal isolates (100% inhibition). All tested oils were significantly reduced dry weight of the tested fungi. However, anise oil was the most effective one, it reduced dry weights of R. solani, F. oxysporum and F. solani isolates with percent reduction of 98.01, 98.07 and 94.74, respectively. In vivo tests indicated that, anise oil as seed soaking significantly decreased the total mortality by (46.67-100%) in R. solani, (33.40-100%) in F. oxysporum and (13.34-25%) in F. solani. Moreover, Anise oil significantly increased fresh and dry weight of shoot and root of lupine plants (56.3-52.6%) (18.6-34.5%), respectively. | ||
