It is by Elizabeth Bush at Virginia Polytechnic Institute and State University. Damage: Meloidogyne incognita is involved in many disease interactions, eg blackshank of tobacco (Phytophthora parasitica var nicotianae), Granville wilt (Pseudomonas solanacearum) - resistant plants predisposed by M. incognita.Field trials with combined inoculations reduced tobacco crop values by $800/acre over the nematode alone. When it attacks the roots of the plants, it sets up a feeding location where it deforms the normal root cells and establishes giant cells. The scientific name Meloidogyne refers to the lemon-shaped females. This nematode gained the household name of “southern root-knot” nematode because of its tendency to attack the roots of the plant. The gill nematode or grilles (Meloidogyne incognita), is a plague of low impact in the traditional olive grove, thanks to the rusticity of the olive tree.The olive tree nurseries and the new plantations of olive groves on crops previous tobacco, cotton, sunflower… may have problems, being necessary to monitor the infections of Meloidogyne incognita. Plant parasitic nematodes such as Meloidogyne incognita have a complex life cycle, occurring sequentially in various niches of the root and rhizosphere. Losses of potatoes due to Meloidogyne species, mainly M. incognita and M. chitwoodi, are estimated at 25% or more (Mai et al., 1981).

Specific symptoms caused by root knot nematodes on tomato include swelling/knots and galls all over the root system and affected plants may be killed in case of severe infestation ( Sikora and Fernandez, 2005 ; Youssef, 2001 ). Meloidogyne incognita is a nematode, a type of roundworm, in the family Heteroderidae.It is an important plant parasite classified in parasitology as a root-knot nematode, as it prefers to attack the root of its host plant.. (1999) who reported that the Ma gene from Myrobalan plum (Prunus cerasifera) conferred resistance to M. mayaguensis. It attacks the roots by wrapping around them and destroying regular root cells to make its own giant cells. Meloidogyne incognita is a polyphagous plant-parasitic nematode that causes considerable yield loss in agricultural and horticultural crops. Sc. Root-knot nematode species, including Meloidogyne incognita, are the most important of the plant parasitic nematodes, infecting almost all cultivated plants, and are responsible for billions of dollars in crop losses annually [1,2].They are obligatory sedentary endoparasites with a 1- to 2-month life cycle. Image 5389797 is of Southern root-knot nematode (Meloidogyne incognita ) sign on potato. It typically incites large, usually irregular galls on roots as a result of parasitism.
