Spring crimp (Foliar) nematode

Aphelenchoides fragariae

Spring crimp (Foliar) nematode (Aphelenchoides fragariae) is a nematode pest of Strawberry, ferns, begonia and other hosts. . It was first detected in Florida in 1960.

This Nematode is an endoparasite in leaves and enters leaves through stomata or directly but also feeds ectoparasitically on leaf and flower buds in strawberry. Nematode feeding causes blotches and necrotic lesions between veins on fern leaves which start as water-soaked spots and then turn brown. .
