Nematodes in fruit orchards

Nematodes constitute one of the major limiting factors in fruit crop production.

They cause extensive root necrosis resulting in serious economic consequences viz., fertilizers are not effectively utilized, the period from planting to harvesting is extended, drastic reduction in fruit or bunch weights, the quality of fruits is impoverished and fields have to be replanted every 2 to 3 years because of drastic reduction in plant numbers.

Furthermore, roots damaged by nematodes are easy prey to fungi which invade the roots and accelerate root decay.

The root-knot nematode Meloidogyne incognita, the burrowing nematode Radopholus similis and citrus nematode Tylenchulus semipentrans are the major nematode pests that infect these fruit crops.
