Citrus nematode is a sedentary semi-endoparasite that attacks roots by burrowing its anterior end deep inside the root cortex while the posterior end remains outside in the soil. Feeder roots particularly in the upper soil layer are destroyed as nematode prefers to habitat upper soil layers, resulting in reduced uptake of water and minerals.

The citrus nematode—tylenchulus semipenetrans—is known to be in the 14 counties of california where there are commercial plantings of citrus. The nematode is a parasitic pest that feeds on the roots of citrus trees. Its feeding decreases vigor and rate of tree growth and the yield and size of fruit.
However, the root’s capacity to carry water and nutrients is impeded and yields are noticeably reduced early in the life of the tree. Nematode damage of the roots also promotes entry of secondary diseases. Citrus nematodes are most active in the warmer months from september to april.
