Abstract AR
يعد التعفن التاجي من أخطر الأمراض التي تصيب محصول الجلبان في العديد من دول الحوض الأبيض المتوسط من بينها الجزائر بسبب الفطر MYCOSPHAERELLA PINODES.
إن الدراسة العوامل المثبطة لهذا المرض أظهرت وجود جذ مات على مستوى الجذور تصنف من بين Actinomycetes خلال هذا الدراسة تم عزل سلالة من جنسي Streptomyces تم التعرف عليها بواسطة اختبارات مرفولوجية.
فيزيولوجية و بيوكيماوية أما التجارب الميدانية فقد بينت مدى تأثيرها على تخفيف من حدة التعفن عند البذور التي تم حقنها بواسطة : Streptomyces بواسطة حوامل عضوية أو معدنية, و كانت هذه التخفيضات تصل إلى أقل من خمسة بالمئة مقارنة بتلك التي لم يتم معالجتها.
Abstract EN
Peas is highly susceptible to preemergence damping off, caused by Mycosphaerella pinodes in western Algerian regions.
Rhizosphere actinomycetes which were antagonistic this pathogen was isolated from chellif soils.
An isolate of Streptomyces (St7c5) provided superior seed protection.
Increased in both the germination and plant growth were recorded following treatment of seeds with Streptomyces formulated with inert or organic charge when compared to control.
Application of the antagonist agent resulted in a significantreduction of Mycosphaerella foot rot to 5 % compared to untreated seeds (30.5 %).
Application of Streptomyces resulted in a significant reduction of blight symptoms when compared to the control or when treated with talc alone.
Hence, the talc formulation of Streptomyces agent can be recommended as one of the crop strategies for the management of foot rotting and blight caused by Mycosphaerella pinodes.
