Integrated pest management (IPM) for nematodes requires: 1) determining whether pathogenic nematodes are present within the grove; 2) determining whether nematode population densities are high enough to cause economic loss; and 3) selecting a profitable management option. Attempting to manage nematodes may be unprofitable unless all of the above procedures are carefully followed. Similarly, some management methods pose risk to people and the environment. Therefore it is important to know that their use is justified by the actual conditions in a grove.

Although many different species of nematode have been found in association with citrus roots, relatively few have been documented to be economically important. The nematode species of major economic importance in Florida include the citrus nematode (Tylenchulus semipenetrans), causal agent of "slow decline" of citrus; and the burrowing nematode (Radopholus similis), causal agent of "spreading decline" of citrus. Other species of limited economic importance because they are more localized include the sting nematode (Belonolaimus longicaudatus) and two species of lesion nematode (Pratylenchus coffeae and P. brachyurus).
