درس في هذا البحث تأثير تراكيز مختلفة من مستخلصات بذور نبات اليانسون Pimpinella anisum L. الميتانولية و المائية بالإضافة للزيت في نمو الفطرين Fusarium oxysporum و Aspergillus niger ، و قد أظهرت جميع المستخلصات تأثيراً تثبيطياً واضحاً تجاه الفطرين الممرضين. تباينت الفعالية التثبيطية باختلاف التراكيز المستخدمة من المستخلص و نوع المذيب. عند استخدام المستخلص الميتانولي بالتراكيز (2، 4 و 6) ملغ/ مل بلغت النسبة التثبيطية في اليوم السابع 42.5، 50.6، 64.4 % للفطر F. oxysporum على التوالي. و 23.6، 42.7، و 55.1 % للفطر A. niger على التوالي. و بلغت النسبة التثبيطية لنمو الفطر F. oxysporum في اليوم السابع 59.2، 65.3 و 70 % على التوالي عند استخدام المستخلص المائي بالتراكيز السابقة، و وصلت إلى 46.1، 58، و 61 % عند الفطر A. niger. في حين سجل المستخلص الزيتي أعلى نسبة بلغت 100% عند 50 و 75 ميكرولتر للفطرين المدروسين.
A Study was carried out to evaluate the ability of the methanolic, hydro and oily extractions of anise seeds (Pimpinella anisum L.) to inhibit the growth of the pathogenic fungi Fusarium oxysporum and Aspergillus niger. The results showed a good inhibition ability of the alcoholic and hydro extractions on the growth of the studied fungi. The inhibition ability differed due to the used concentrations. When the methanolic extraction was used by concentrations (2, 4, and 6) mlg/ ml at the seventh day, the inhibition ability was (42.5, 50.6 and 64.4)% of the fungus F. oxysporum, respectively. And was (23.6, 42.7 and 55.1)% of the fungus A. niger, respectively. Whereas when the hydro extraction was used by the same concentrations, the inhibition ability was (59.2, 65.3 and 70)% respectively for the fungus F. oxysporum, and (46.1, 58 and 61)% for the fungus A. niger, respectively. The oily extraction showed high inhibition ability, where the inhibition rate was 100% when the extraction was used by the two concentrations 50 and 75 μl for both two studied fungi.

Fuarium oxysporum fragariae, which effects the strawberry plants
in the green house in The Syrian coast, is one of the main problems.
The study showed that the rate of infection of it between 12.1 to
17.95%. And the fungus were isolated the fungus from the roots and
crowns and soil , while is olation from stolons and leaves was not
feasible.
The research was conducted in order to test the effect of each of the
filtrate T. viride and chitosan and sodium benzoate in filamentous
growth pathogenic fungi F. oxysporum and F. solani, and their
impact in protecting the seeds of peppers from t
hese two fungi, and
then assess the effectiveness of peroxidase enzyme in pepper plants
from seeds treated with the above-mentioned compounds.
The effect mycorhizal fungi on tomato wilt disease caused by Fusarium oxysporum
was studied. The results showed that % of disease incidence reduced in treatment whit
mycorrhizal fungi . % of disease incidence reached to 33% when plants infected wit
h
mycorrhizae and Fusarium wilt compared to plants infected with Fusarium wilt just
where% of disease incidence reached to 70% .The results showed a sighificant increased in
plant height ,leaf number , fresh and dry matter of shoot and root in treated plants with
mycorrhiza and Fusarium wilt compared whit treated plants with Fusarium wilt.The
increase in plant height reached 24.13% ,16.93% in leaf number,36.13% in wet weight of
shoot ,48.14 in wet weight of root,30.37% in dry weight of shoot and 29.18% in dry
weight of root in treated plants with mycorrhiza and Fusarium wilt.
This investigation carried out in 2012-2013,in department of plant protection-
Damascus Unv., to study the effect of ethanol and water extracts of Allium sativum L.,
Inula viscos L., Thymus vulgaris L. and Melia azedarach L., in inhibition mycelium
growth of fungi Alternaria alternata and Fusarium oxysporum and compared with
fungicides (carbendazim and chlorothalonil) on PDA in the laboratory. The result showed
that ethanol extracts of studied species gave significant inhibition to growth fungi
compared with the control. The ethanol and water extract of the Allium sativum gave the
superior effect inhibition to F. oxysporum where gave 100% inhibition at 600 and 1000
mg/l. at respectively, and gave100% inhibition to A. alternata at 1000 mg/l. Followed with
the ethanol extract of Inula viscos. While, the ethanol and water extract of the Melia
azedarach gave the lowest inhibition to growth study fungi. Where didn’t gave 100 %
inhibition to F. oxysporum and A. alternata at 1000 mg/l. On the other hand, the ethanol
extract of Thymus vulgaris gave moderate inhibition to F. oxysporum, while the inhibition
of A. alternata was little. The ethanol extract of tested plants gave the superior effect
inhibition to both fungi compared with water extracts. On the other hand, the obtained
results showed that carbandazim gave the superior inhibition for F. oxysporum ,where gave
100% inhibition at concentration 120 mg/l. While the fungicide chlorothalonil gave the
lowest inhibition to F. oxysporum. At contrast, the fungicide chlorothalonil gave the
highest inhibition to A. alternata at used concentration. Where cause 100% inhibition at
150 mg/l. On the other hand, Effect of plant extracts and fungicides increased with increase
of concentrate. We can arranged the effect of plant extraction at the values (ED50): Allium
sativum L., Inula viscos L., Thymus vulgaris L. and Melia azedarach L., Therefore we
recommended to use the ethanol extract of the Allium sativum L., Inula viscos L. as
environment friendly fungicides.
This study was carried out to evaluate the inhibitory effect of aqueous, ethanolic and
methanolic extracts of the cladodes, flowers and fruits cactus plant (Opuntia ficus-indica)
with concentrations of (125, 250, 500, 1000) mg/ml against the isolat
ion of Aspergillus
niger fungus and compared it with aqueous solution of antibiotic (fluconazole) at
concentration 10 μg/ml. The study showed a difference in efficacy of studied extracts in
inhibiting the growth of studied fungus, The methanolic extract of flowers showed higher
inhibiting ratios (76.86, 81.32) % at concentrations (500, 1000) mg/ml respectively,
followed by the methanolic extract of cladode by inhibiting ratios reached (73.49, 76.14) %
at the previous concentrations, then followed by the ethanolic extract of flowers by
inhibiting ratio (40.96, 57.83) % at the same of previous concentrations, while inhibiting
ratio of fluconazole reached 65.66% at the used concentration, whereas the aqueous
extracts of flowers, fruits and cladode had the lowest effect by inhibiting ratios reached
(36.74, 23.49, 12.53) % respectively at concentration 1000 mg/ml.
