Foliar nematode
Group of roundworms
Foliar nematodes are plant parasitic roundworms in the genus Aphelenchoides.[1] The three most economically important species are Aphelenchoides fragariae, A. ritzemabosi, and A. besseyi. Foliar nematodes are becoming a widespread and serious problem for the ornamental and nursery industries. A. fragariae causes damage on hundreds of different plants including chrysanthemum, begonia, gloxinia, African violet, cyclamen, and a wide variety of bedding plants and ferns, causing brown to black, vein-delimited lesions on leaf tissue, defoliation, and possible stunting of plants.
