Guava root-knot nematode (GRKN, Meloidogyne enterolobii) is a damaging microscopic pest, found mainly in tropical areas. In Australia, it has been found in residential gardens and commercial farms in the Northern Territory and limited sites in Queensland. Its potential spread is uncertain, and its wide host range and absence of resistant hosts complicate control and increase potential damage.

This guide outlines how to sample for GRKN, and what you should do if you suspect it.
