Nikmaram, S., Sadravi, M., & Ghaderi Zefrehee, M. (2024). The impact of three arbuscular mycorrhizal fungi on wheat take-all disease caused by Gaeumannomyces graminis var. tritici. Plant Pathology Science, 13(1), 104-112.
Take-all caused by soil-borne fungus Gaeumannomyces graminis var. tritici is one of the most important diseases of wheat in the world, reported to cause up to 50% yield losses. The disease has also been reported from different areas of wheat cultivation in Iran. Biological control is a healthy and environment-friendly method for managing plant diseases, and arbuscular mycorrhizal fungi can play an important role in this field. This research was conducted to determine the effect of three arbuscular mycorrhizal fungi on the severity of this disease. The pathogen was isolated from diseased wheat plants in Kigiluyeh and Boyar-Ahmad Province, southwestern Iran. The effect of three arbuscular mycorrhizal fungi; Funneliformis mosseae, Rhizoglomus intraradices, and Blaszkowskia deserticola alone, and in combination on the disease severity and growth indices of wheat was tested under greenhouse conditions in a completely randomized design. All treatments of mycorrhizal fungi reduced disease severity and increased growth indices compared to control plants, but F. mosseae was more effective than others. Therefor
F. mosseae can be used to reduce the severity of the disease and improve the growth indices of wheat.
