الملخص الإنجليزي

This study was conducted to evaluate efficiency of the antifungal activity of Silybum marianum and Juglans regia(Bark) ethanol extracts against Rhizoctonia solani which is the most cammon cause of seed decay and seedling damping-off on tomato, in culture medim and under greenhouse condition.

The results showed that addition of Silybum marianum ethanol extract into potato dextrose agar (PDA) at concentrations of 5, 10, 15, 20 mg/ml caused an inhibition of fungal growth 42, 44, 45, 85% respectively compared with zero inhibition in control (without extract), while addition of Juglans regia ethanol extracts into potato dextrose agar (PDA) at 5, 10, 15, 20 mg/ml concentrations caused an inhibition of 41, 61, 100, 100% respectively .

In greenhouse condition, treatment seed with Silybum marianum and Juglans regia ethanol extracts at 20 and 10 mg/ml respectively was led to increase the percentage of seed germination and reduced percentage of post emeraence damping off compared with control treatment.

The percentage of seed germination and post emeraence damping off were reached 65, 15% respectively with Silybum marianum ethanol extract , while were reached 48.3, 8.3% respectively with Juglans regia ethanol extracts , compared with control treatment with the presence where the seed germination and post emeraence damping off were reached 36.7, 32.7 respectively, which indicate that the active compound in the extracts controling of this pathogen.The ethanol extracts of two plants found to be more efficiente in creasing the fresh and dry weights in tomato plants.The treatment seed with Silybum marianum was found to be more efficient in creasing the fresh and dry weights compared with treatment seed with Juglans regia.
