Uses
The tree cassava was used a source of rubber, instead of Hevea brasiliensis throughout the world. The plant is introduced largely in the world, but now it is classified as one of the highly invasive plant of the world.

This species is useful in cassava breeding because it is a wild relative. Several quantitative trait loci (QTLs) are known to be usable or in use for introgression into cultivated cassava. This includes those for cassava brown streak disease resistance found by Abaca et al., 2013 and four found by Nzuki et al., 2017.

Invasiveness
The species is invasive in New Caledonia.
