The Role of Arbuscular Mycorrhizal Fungi (AMF) in the Control of Rhizoctonia Root Rot in Local Bean Genotypes of the Van Lake Basin

Abstract

Beans (Phaseolus vulgaris L.), one of the main vegetables common in the Van Lake Basin, are frequently grown in the region with local genotypes. Rhizoctonia solani root rot, an important soil-borne disease that negatively affects beans, especially in this region, causes economic losses in our country and worldwide. Therefore, a viable and eco-friendly alternative to chemical control in the treatment of such significant soil-borne plant diseases is the application of Arbuscular Mycorrhizal Fungi (AMF). This study aimed to investigate the effects of commercial AMF (ERS) and Funneliformis mosseae (Fm) against R.solani (Rs) root rot disease in V29 and TR 50763 (T71) bean genotypes obtained from Van-Geva & scedil;. For this purpose, some plant growth parameters, total phenol, total antioxidant capacity, root colonization, and disease severity parameters were investigated. Fm and ERS significantly increased plant morphological parameters and reduced disease severity in both bean
