مستخلص المنشور

Sclerotium stem and tuber rot diseases caused by Sclerotium rolfsii is a

significant problem facing the Jerusalem artichoke cultivation. The objective of this study

was to evaluate the efficacy of biotic and a biotic agents in control of stem and tuber rots

of Jerusalem artichoke. For this purpose, Trichoderma atroviride and T. reesei were

isolated from rhizosphere of healthy Jerusalem artichoke plants. These isolates positively

antagonized S. rolfsii. Arbuscular mycorrhiza, mixture of the previous Trichoderma

species and/or hydroquinone were evaluated under greenhouse and field conditions

against stem and tuber rots. The treatments of arbuscular mycorrhiza+ hydroquinone

and arbuscular mycorrhiza + Trichoderma minimized the disease incidence, improved

the plant growth and yield and enhanced the tuber quality of Jerusalem artichoke. These

data encourage the incorporation of such agents in the rots control and the production

strategies of Jerusalem artichoke.
