تعتبر لفحة الأسكوكيتا، التي يحدثها الفطر Ascochyta fabae f. Sp. Lentis من الأمراض الفطرية المهمة التي تصيب العدس و تسبب أضرارا" كبيرة له . نفذت التجربة الحقلية في محطة بحوث إيكاردا للتجارب الزراعية في منطقة بستان الباشا، جبلة، اللاذقية. على أربعة أصناف من العدس التي تزرع في مناطق مختلفة من سورية و هذه الأصناف هي: ادلب2، ادلب3، ادلب4، و البلدي الأحمر. تم إجراء العدوى الاصطناعية باستخدام عزلة محلية من الفطر Ascochyta lentis بمعدل ثلاث مرات بفارق عشرة أيام بين كل عدوى و أخرى، و اعتمد اللقاح المعدي بتركيز510 بوغة/ملل .
Ascochyta blight, which is caused by the fungus Ascochyta fabae f. Sp. Lentis, is considered as a very important fungal disease that infects lentils and cause it damage. The experiment was conducted in ICARDA research station for agricultural experiments in the orchard area Basha, Jableh, Lattakia in four varieties of lentils that are grown in different parts of Syria, and these varieties are: Idleb 2, Idleb 3, Idleb 4, and municipal red. Artificial infection was performed using a local isolation of the fungus Ascochyta lentis with an average of three times and ten days between each infection and the other. The infectious vaccine adopted a concentration of 105 Båge / ml.

Lentil, lens culinaris Medik in Syria , is the most important food legume crop in terms of its nutritive value and area cultivated. The crop suffers, during its growth stages, from infection with several pets and diseases, amongst which. lentil vascu
lar wilt caused by Fusarium oxysporum Schlecht and Snyder f. sp. lentis is the most important because of the substantial yield losses it caused, that may reach in severely infected areas to 100%
To study the effect of some fungicides invitro on an isolate of the fungus Cladosporium fulvum(cook) that causes leaf mold on tomatoes, five fungicides were tested Flint - Topsin-M- Score and Collisand Indofil-M at concentrations between 1 - 4000 p
pm. The results showed that Score and Indofil-M were the most effective fungicides inhibiting hyphal growth for the isolate even at 10ppm. Also, they inhibited completely the spores germinatios at the 100 ppm. The effects of fungicides Flint and Collis were weak on hyphal growth of the isolate and inhibited almost completely the spores germinatios at 1000 ppm. We didn,t observe clear inhibiting effects of Topsin-M on hyphal on the growth of the spores germinatios at 1000 ppm .

We conducted an assessment of some of the phenological characteristics and morphological and productivity of the six genotypes of lentils, namely, (Idlib 1, Idlib 2, Idlib 3, Idlib 4, balade, Kurdi), using some statistical indicators in conditions Sermin region, located around 25 km from the province of Idlib,
A study was carried out in the 2nd agro-ecological zone at the General Commission
for Scientific Agricultural Research/Sirbaya Research Station/Aleppo during the growing
season 2011-2012. The study aimed at evaluating the response of different vari
eties of
lentil to supplemental irrigation. The experiment adopted a split plot design with three
replicates. Two water treatments, supplemental irrigation (R) and rain feed (Ro) were
applied to three varieties of lentil: IDLEB1 (D1), IDLEB1 (D2), and IDLEB1 (D3). The
results showed that R was more significant than Ro at a confidence level 5% for grain, hay
yield, and 100-grain weight. The differences were significant between the varieties that
applied Ro; the most significant of which was D3 for grain and hay yield, and D2 for 100-
grain weight. As for R, the differences were significant for grain yield (the most significant
was D3) and 100-grain weight (the most significant was D2), while there was no
significant difference for hay yield. There was no interaction between water treatment and
the variety in terms of grain yield and 100-grain weight, while it was observed for hay
yield.
