Interpretive Summary: The Kona Coffee Root-knot nematode negatively affects the health and yield of Arabica coffee trees in Hawaii. Symptoms are difficult to diagnose and may appear as nutrient deficiencies or drought stress. Sampling of coffee farms for the presence of root-knot nematodes can assist growers in making management decisions such as replanting with trees grafted on nematode tolerant rootstocks. Adopting this grafting technique enables trees to remain vigorous and improves yields in nematode infested fields. This extension bulletin outlines the proper procedures for sampling coffee roots and soil for an accurate diagnosis of root-knot nematode infestation.
