هدفت الدارسة إلى إجراء مسح حقلي لانتشار مرض الذبول الفطري الوعائي على نبات الحُمّص Fusarium oxysporum f.sp ciceris
في شمال سورية، و دراسة العوامل التي
تُسهم في زيادة المرض. جرت عمليات المسح الحقلي للمرض في معظم مناطق زراعة الحُمّص
في شمال سو رية خلال عام 2011 ، جُمع خلاليا 250 عينة، مثلت محافظات الحسكة و حلب و ادلب. اختلفت نسب الإصابة بين المواقع و ضمن الموقع الواحد (2-90 %)، و كان أعلى
متوسط للإصابة في موقع الفوعة- ادلب ( 90 %). كما بينت الدراسة تأثّر المرض بالعديد من
العوامل و لاسيما موعد الزراعة و نوع التربة. بينت نتائج القدرة الإمراضية على 60 عزلة تتبع النوع
Fusarium oxysporum تبعية 54 عزلة للنمط الممرض Fusarium oxysporum
سببت 32 عزلة منها أعراض اصفرار و 22 عزلة أعراض ذبول على الصنف الحساس غاب 1.
A field survey for chickpea wilt disease Fusarium
oxysporum f.sp ciceris was conducted in different provinces
of north Syria during 2011 cropping season with the
objectives to determine chickpea wilt distribution and factors
affecting its development. Two hundred and fifty samples
were collected from Alhasakah, Aleppo and Idleb fields. The
results showed varying levels of incidence between and
within provinces (2-90%), and the highest incidence was
recorded in Alfouaa- Idleb (90%). The incidence and
distribution of this disease seemed to be affected by many
factors especially date of sown and soil kind. The
pathogenicity test of 60 isolates related to Fusarium
oxysporum on susceptible cultivars Ghab1 was shown that 54
isolates related to Fusarium oxysporum f. sp. ciceris; 32
isolates of them were caused yellowing symptoms and 22
were caused wilting symptoms.
