يعد الفطر Fusarium oxysporum fragariae الذي يصيب نبات الفريز في الزراعة المحمية في الساحل السوري من المشاكل الرئيسة، حيث أظهرت الدراسة إن نسبة الإصابة به تتراوح بين 12.1-17.95%. و قد تم عزل الفطر من جذور و تيجان و تربة النباتات المصابة، و لم ينجح عزله من مداداتها و أوراقها.
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.
The effect of six bacterial isolates of Proteus genus were studied the on
causative of Fusarium axysporum f.sp ciceris in both the glasshouse and
the field.
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.
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 in
hibition
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.
sixteen isolates of Fusarium oxysporum f. sp. ciceris (Foc ),
representing six provinces (Al Hasakah, Aleppo, Idlib, Hamah,
Homs and Dara) of Syria were analyzed for pathogenic
variability on a set of 10 differential cultivars of chickpea.
