Belonolaimus longicaudatus is among the most damaging of all plant-parasitic nematodes. Feeding by this nematode kills the root meristem and halts root growth. Lateral roots will develop, but Belonolaimus longicaudatus will migrate to these lateral roots and damage them as well. This causes an abbreviated and stubby-looking root system. Turfgrass roots may appear cropped off just below the thatch. Because the roots are damaged, they are unable to supply the plant with water and nutrients. Damaged annuals will become stunted, wilt, and die. Young citrus trees infected by Belonolaimus longicaudatus may require extra years after planting before bearing fruit. Corn and cane may lodge (fall over) as the nematodes damage their brace-roots. Turfgrasses may wilt and decline, and weeds may proliferate . Damage from Belonolaimus longicaudatus typically occurs in patches because the nematodes are generally clumped in distribution.
