Research summary
تتناول هذه الدراسة تأثير زيت اللافندر بتركيزات مختلفة على نمو فطري Fusarium oxysporum وAcremonium strictum. أظهرت جميع التركيزات المدروسة تأثيرًا تثبيطيًا واضحًا ضد الفطريين، حيث أظهرت التركيزات (0.06-0.04-0.03-0.02-0.01 مل/غ) تثبيطًا بنسبة 100% ضد A. strictum، بينما كانت نسبة التثبيط 64.51% عند التركيز 0.002 مل/غ و58.04% عند التركيز 0.004 مل/غ و35.48% عند التركيز 0.001 مل/غ في اليوم السابع من الحضانة. بالنسبة لفطر Fusarium oxysporum، أظهرت التركيزات (0.06-0.04-0.03-0.02-0.01-0.006-0.004-0.002 مل/غ) تثبيطًا بنسبة 100%، بينما كانت نسبة التثبيط 38.82% عند التركيز 0.001 مل/غ في اليوم السابع من الحضانة. تم تحديد التركيز القاتل الأدنى (MBC) لزيت اللافندر ضد A. strictum بـ 0.01 مل/غ والتركيز المثبط الأدنى (MIC) بـ 0.02 مل/غ، بينما كانت قيمتي MIC وMBC ضد F. oxysporum متساويتين وبلغتا 0.002 مل/غ. توصي الدراسة باستخدام زيت اللافندر كوسيلة فعالة وغير ضارة لمكافحة الفطريات الممرضة للنباتات.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة مهمة نحو استخدام الزيوت العطرية كبديل آمن وفعال للمبيدات الكيميائية في مكافحة الفطريات الممرضة. ومع ذلك، هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الأفضل تضمين تجارب ميدانية لتأكيد النتائج المخبرية في ظروف زراعية حقيقية. ثانيًا، لم يتم تحليل التركيب الكيميائي الدقيق لزيت اللافندر المستخدم، مما يجعل من الصعب تحديد المركبات الفعالة المسؤولة عن التأثيرات المثبطة. أخيرًا، يمكن توسيع الدراسة لتشمل فطريات أخرى ممرضة للنباتات والإنسان لتعميم النتائج بشكل أوسع.

This study was conducted to determine the effect of lichen Evernia prunastri extracts (acetone, ethanol, and chloroform) against the two species of plant pathogenic fungi were Fusarium oxysporum, F.solani. All extracts showed has inhibition influence evident in the growth of fungal and germination of spores of two compared to the control.
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.
In this research was studied the effect of different concentrations of (ethanolic – methanolic – acetonic) extracts of Apium nodiflorum on growth of fusarium moniliforme all extracts revealed clear inhibitory effect against this Fungi. The inhibit ory effect differenced as difference of parts of plant and the difference of using concentrations from extract and a kind of solvent. The MIC of different extracts ranged between 0.02 and 0.1 g/ml , The Acetonic extract of stem was the more activity comparing with the other parts of plant inhibition was completed at (0.02 g/ml) concentration. For methanolic extract, the extract of whole plant and flowers was more activity and the MIC was 0.08 g/ml for etanolic extract of flowers recorded the highest percentage of inhibition incomparing with. The other parts of plant and it reached 0.06 g/ml.
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 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.
