Damage:

coffee root-knot nematode, Meloidogyne arabicida  (Tylenchida: Heteroderidae) - 1356087

Besides causing direct damage to coffee, M. arabicida is involved in a disease complex with Fusarium oxysporum which is known as corchosis or corky root and is expressed as a corky texture and cracking sympoms on main and secondary roots (Humphreys-Pereira et al., 2014).

Corky root symptoms of the disease complex induced by Meloidogyne arabicida and Fusarium oxysporum.
