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

İngilizce (OpenAlex)

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-Gevaş. 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 genotypes (V29 and T71) despite the R.solani inoculated pathogen. Furthermore, Fm was shown to be the most effective in plant growth among AMF treatments. ERS was the most effective treatment in total phenol concentration, antioxidant activity, and AMF root colonization. In general, it was observed that genotype T71 had a different effect on plant growth parameters and total antioxidant activity than V29. The study's results show that AMF, a sustainable agricultural technique, enhanced plant growth and reduced the damage caused by the important Rhizoctonia root rot disease in beans, regardless of genotype diversity. This study can be positively evaluated in the context of investigating sustainable agricultural measures against this disease in the field.
