Rosellinia bunodes is a fungal plant pathogen that causes black root rot, colonizing plant roots and damaging vascular tissue in a broad range of herbaceous and woody perennials across tropical and subtropical regions. Documented hosts include tea, citrus, coffee, yam, fig, rubber, cassava, banana, avocado, pepper, potato, cocoa, ginger, daffodil, yerba mate and poplar. It behaves as an opportunistic soil saprophyte capable of infecting hosts at any stage of development, spreads through soil by mycelia and rhizomorphs, and is agriculturally significant across major crop-producing regions of the Americas, Africa, India, Indonesia, the Philippines and Sri Lanka.

Article text
Some research has shown biocontrols using mycorrhizal or mycoparasitic fungi (i.e.: Trichoderma spp., Clonostachys spp., Glomus manihotis, and Entrophospora colombiana) to be effective in suppressing the disease, but it is not clear if these interventions are successful only in certain environments or in specific host-pathogen combinations.
Article text, control method
Fungicide treatments usually include broad-spectrum approaches such as metam sodium, benzimidazoles, chlorophenyls, imidazole, morpholine, oxathiin, triazoles, and some inorganic compounds.

Horticultural practices such as canopy pruning to reduce soil humidity can also be effective in disease prevention.
