Meloidogyne incognita (root-knot nematode, RKN), also known as the southern root-nematode or cotton root-knot nematode is a plant-parasitic roundworm in the family Heteroderidae. This nematode is one of the four most common species worldwide and has numerous hosts. It typically incites large, usually irregular galls on roots as a result of ...
Northern root-knot nematode (Meloidogyne hapla) is a species of vegetable pathogens which produces tiny galls on around 550 crop and weed species. They invade root tissue after birth. Females are able to lay up to 1,000 eggs at a time in a large egg mass. By surviving harsh winters, they can survive in cold climates (hence, the name, Northern).

Meloidogyne javanica is a species of plant-pathogenic nematodes. It is one of the tropical root-knot nematodes and a major agricultural pest in many countries. It has many hosts.
Root-knot nematodes (Meloidogyne spp.) are one of the three most economically damaging genera of plant-parasitic nematodes on horticultural and field crops.Root-knot nematodes are distributed worldwide, and are obligate parasites of the roots of thousands of plant species, including monocotyledonous and dicotyledonous, herbaceous and woody plants.
It is approved as a biological-based nematicide against root-knot nematodes in crops by the European Commission. [ 8 ] It has been used as a biopesticide to control Meloidogyne incognita , or southern root-knot nematode, and Pseudopyrenochaeta lycopersici , a fungal plant pathogen, on the growth of tomato crops in an integrated pest management ...

The fungus is being researched for use in biological control of root-knot nematodes. Compared to other nematophagous fungi it is rather slow growing. A. dactyloides has been mass-reared in liquid culture but because it is sensitive to desiccation, it has not been possible to use fast drying procedures. However, this problem has been overcome ...
