Rhizoctonia solani Kühn is a pathogenic fungus that causes root rot diseases in mung bean plants, Vigna radiata (L.) R. Wilczek, which can reduce productivity and even cause plant death. One way to control this disease is to use biological control agents, including binucleate Rhizoctonia (BNR). This study aimed to examine the effect of nonpathogenic BNR inoculation on plant growth and disease severity in mung bean plants infected with R. solani. Characterization and identification were performed by evaluating the morphological features of the isolate. An inhibition test was done by dual culture methods. A greenhouse test was also conducted using mung bean plants for 7 weeks, using the completely randomized design with five repetitions. The treatments used were mung bean plants without inoculation (control), BNR inoculation, R. solani inoculation, and R. solani + BNR inoculation. Based on the morphological characteristics, the BNR belonged to Ceratorhiza sp. The dual culture showed that BNR inhibited R. solani by 53.92% through competition and mycoparasitism. BNR increased plant height by 34.04 cm, the number of leaves, and shoot fresh weight by 63% in plants inoculated with R. solani. Disease severity of R. solani was reduced by 58% when BNR was present. Based on the findings, BNR is considered a potential biocontrol agent for R. solani through competition and mycoparatism mechanisms, improved growth, and reduced disease severity.
