Of late, rice root-knot nematode, Meloidogyne graminicola has emerged as a major threat throughout the world due to its adoptable nature, broad host range and ability of causing potential yield loss. The losses caused by M. graminicola may vary from 16-80 %. The daignostic symptoms of root knot disease of rice are, stunted growth, yellowing, and gall formation on the roots of rice plants. The degree of symptom manifestation depends on several factors, viz., time of infection, age of the plants and load of inoculums. Abiotic factors such as nutrition, temperature, soil type, moisture, etc., play on important role on nematode population. Indiscriminate use of chemicals for managing this disease results in the development of pathogen resistance and risk to the environment. Ecofriendly approaches such as, removal of host weeds, flooding of fields, summer ploughing, organic amendments, and use of effective biocontrol agents and resistant cultivars has some advantage in managing the disease.
