“…Virus vectoring nematodes : There are two different types of nematode transmitted viruses based on the viruses’ particle shape: NEPO viruses (nematode polyhedral viruses) and TOBRA viruses (tubular or rod-shaped viruses) Taylor, 1972 ).…”

“…NEPO viruses are transmitted by Xiphinema (dagger) and Longidorus (needle) nematodes; both ectoparasitic nematodes are large and slender. Their host range consists of perennial and woody plants, grapevines, orchids, and small fruits Taylor, 1972 ; Handoo, 1998 ). Main NEPO viruses for ornamental plants, such as geraniums, petunia, and tulips, are tomato ringspot virus (ToRSV), tobacco ringspot virus (TRSV), Arabis mosaic virus (ArMV), and tomato black ring (TBRV) virus Engelmann and Hamacher, 2008 ).…”

“…TOBRA viruses are transmitted by Trichodorus and Paratrichodorus species (stubby root nematodes), which are thick nematodes with a curved stylet. Similar to dagger and needle nematodes, they feed externally at the root tip, causing the root tips to swell and become stubby Taylor, 1972 ). The main viruses are Tobacco mosaic virus (TMV), Tobacco rattle virus (TRV), Pea early-browning virus (PEBV), and Pepper ringspot virus (PepRSV) which can affect plants like petunias, tulips, and lilies Taylor, 1972 ; Handoo, 1998 ; Engelmann and Hamacher, 2008 ; Macfarlane, 2010 ; Khan, 2015 ).…”

General symptoms of TOBRA viruses include chlorotic and necrotic spots or strips on leaves, mosaic, mottling, light or dark colored flecks on flower petals, oval lesions, flower malformation, and stunted plants Engelmann and Hamacher, 2008 ; Madhavan et al, 2021 ).…”

Worldwide, the ornamental plant industry is estimated to be valued at $70 billion, with the United States’ ornamental plant industry valued at $4.8 billion in 2020. Ornamental plants are cultivated for numerous reasons worldwide, such as decorative, medicinal, social, and utility purposes, making the ornamental field a high growth industry. One of the main pathogen groups affecting the yield and growth of the ornamental plant industry is plant-parasitic nematodes, which are microscopic roundworms that feed on plant parts causing significant yield loss. There are many kinds of plant-parasitic nematodes that affect ornamental plants, with the main genera being Meloidogyne spp., Aphelenchoides spp., Paratylenchus spp., Pratylenchus spp., Helicotylenchus spp., Radopholus spp., Xiphinema spp., Trichodorus spp., Paratrichodorus spp., Rotylenchulus spp., and Longidorus spp. The aim of this review is to focus on the effects, hosts, and symptoms of these major plant-parasitic nematodes on ornamental plants and synthesize current management strategies in the ornamental plant industry.
