Meloidogyne fallax and Nacobbus aberrans
False root‑knot nematodes are soilborne microscopic roundworms that trigger galls to kind on plant roots, mimicking the signs brought on by true root‑knot nematodes (Meloidogyne spp.).
They’re of explicit concern in agriculture as they will have an effect on a number of plant households and should not reply to manage strategies used to deal with true root-knot nematodes.
Whereas a lot of the documented influence has been noticed in large-scale crop manufacturing, dwelling gardeners ought to nonetheless pay attention to the signs, host vegetation, and methods for management.
Learn on to study extra about false root-knot nematodes.
Right here’s what I’ll cowl:
What Are False Root-Knot Nematodes?
The 2 species generally generally known as false root-knot nematodes are Nacobbus aberrans and Meloidogyne fallax.
Nacobbus aberrans was first described within the Thirties and later recognized on sugar beets in Nebraska in 1949.
Though it’s handled as a single species, mounting proof suggests it must be thought of a species advanced, a bunch of carefully associated however genetically distinct populations.
Distinctive pathotypes have been documented that exhibit differing host preferences reminiscent of beans, potatoes, or sugar beets, and happen throughout a variety of habitats.
Its identified distribution consists of a number of US states reminiscent of Nebraska, Wyoming, Colorado, Utah, Montana, and South Dakota, in addition to elements of Mexico and South America.
Meloidogyne fallax, typically referred to as the false Columbia root‑knot nematode, was first documented on potatoes within the northern United States within the Nineteen Eighties.
It has since been reported in areas of Europe, Africa, Oceania, and different elements of the Americas. Like different Meloidogyne species, it impacts quite a few agricultural crops together with tomatoes, carrots, leeks, in addition to turf grasses.
Since each species can infect a variety of vegetation together with many widespread greens and decorative species they’re more and more related to dwelling gardeners, notably in areas the place these pests are spreading or changing into established.
