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.

Research summary
تناول البحث دراسة تأثير مستخلصات بذور نبات اليانسون (Pimpinella anisum L.) على نمو الفطرين الممرضين Aspergillus niger و Fusarium oxysporum. تم استخدام مستخلصات ميثانولية ومائية وزيتية بتركيزات مختلفة لتحديد قدرتها على تثبيط نمو الفطريات. أظهرت النتائج أن جميع المستخلصات كانت فعالة في تثبيط نمو الفطريات، حيث كانت الفعالية التثبيطية تعتمد على تركيز المستخلص ونوع المذيب. المستخلص الميثانولي بتركيزات (2، 4، و6) ملغ/مل أظهر نسب تثبيط تتراوح بين 42.5% و64.4% للفطر F. oxysporum وبين 23.6% و55.1% للفطر A. niger. أما المستخلص المائي، فقد أظهر نسب تثبيط تتراوح بين 59.2% و70% للفطر F. oxysporum وبين 46.1% و61% للفطر A. niger. المستخلص الزيتي أظهر أعلى نسبة تثبيط بلغت 100% عند استخدام تركيزات 50 و75 ميكرولتر لكلا الفطرين. تشير النتائج إلى أن مستخلصات بذور اليانسون تمتلك قدرة تثبيطية عالية تجاه الفطريات الممرضة، مما يجعلها واعدة في مجال مكافحة الفطريات باستخدام مواد ذات منشأ حيوي فعالة دون الضرر بالبيئة.
Critical review
دراسة نقدية: يعتبر هذا البحث خطوة هامة نحو استخدام المستخلصات النباتية كبديل طبيعي للمبيدات الكيميائية في مكافحة الفطريات الممرضة. ومع ذلك، هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الأفضل توسيع نطاق الدراسة لتشمل أنواعاً أخرى من الفطريات الممرضة لتعميم النتائج. ثانياً، لم يتم التطرق بشكل كافٍ إلى الآليات الكيميائية التي تجعل مستخلصات اليانسون فعالة ضد الفطريات، مما يترك مجالاً للتساؤل حول كيفية عمل هذه المستخلصات على المستوى الجزيئي. أخيراً، كان من الممكن تضمين تجارب ميدانية لتأكيد فعالية المستخلصات في ظروف الزراعة الحقيقية، وليس فقط في المختبر.

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.
