الفعالية التثبيطية لمستخلصات نباتي الحناء و الآس على نمو الفطرين Fusarium chlamydosporium و Fusarium oxysporum

الملخص EN

The inhibitory effect of aqueous and ethanolic extracts of two plants Lawsonia inermis and Myrtus communis against the radial growth and the dry weight of two fungal species Fusarium chlamydosporium and F .

oxysporum, were studied.

The ethanolic extract of the two plants gave the maximum inhibitory effect against radial growth of F.

chlamydosporium with an inhibitory percentage 88.8% inhibitory percent in 4000 ppm concentration,also the ethanolic extract of the Lawsonia inermis plant showed the maximum effect in reducing the dry weight of the fungus using 3000 ppm concentration.

comparing with control treatment (0.05 gm, 2 gm) respectively .

Concentration.

for the fungus F.

oxysporum the aqueous extract of Lawsonia inermis plant showed the maximum inhibitory effect on the radial growth which about 88.8 % using 4000 ppm concentration, while the ethanolic extract of the Lawsonia inermis plant gave the maximum effect in reducing the dry weight of the fungus in 3000 ppm concentration in which the fungus gave no growth.
