Abstract

Dendrobium is one of the largest orchid genera in the family Orchidaceae, and includes consists of more than 2,000 species. In nurseries, this orchid is easily attacked by the fungus Fusarium sp. Countermeasures using fungicides will damage the environment and will also inhibit the growth of mycorrhizal fungi that are useful for plants. Rhizoctonia mycorrhiza is a mycorrhizal fungus that is able toprevalently associated with orchids. At In vitro this fungus is able to provides induced resistance to of orchids against pathogenic fungal attacks. The research was conducted in a laboratory and a greenhouse from August to June 2022. The research method used a Completely Randomized Block Design (CRBD) consisting of 2 treatment factors and 5 replications. The first factor is the application of Rhizoctonia mycorrhizae (M1), and the second factor is the origin of the Fusarium inoculum from garlic (F1), from potatoes (F2), and from chili (F3). Tthe highest M1F1 6.62 cm, the number of leaves with the highest value M1F1 6.00 cm, the number of roots with the highest value M1F1 20.20 cm, root length with the highest value of 11.12 cm in M1F1, plant fresh weight with the highest value in M1F3 namely 9.85 cm. And tThe application of Rhizoctonia mycorrhiza had a significant effect on leaf length with the highest value of 4.40 cm in the M1F1 treatment. The application of Fusarium sp also had a significant effect on the number of leaves with the highest value of 6.00 cm on the M1F1 requirement, and the fresh weight of the plant with the highest value on the M1F3 treatment of 9.85 cm. The treatment interaction between Rhyzoctonia mycorrhizae very real different had a significant effect on the number of roots with the highest value of 20.20 cm. This study aimed to use Rhizoctonia mycorrhizae in controlling Fusarium sp. attack on sedling Dendrobium nindii in experimental garden. in the treatment
