Rice Root-Knot Nematode ( Meloidogyne graminicola ): A Major Menace in Rice Production

Abstract

Rice is an important major staple food crop of the world which is affected by various biotic and abiotic stresses. Among biotic stresses, plant parasitic nematodes are considered as major constraints. However, of late, Meloidogyne graminicola has emerged as pest of International importance and it is considered as number one enemy of rice crop. Being a soil borne and hidden organism in rice causes a yield loss up to 80%. Due to its adaptation, distribution, broad host range and ability to survive under different abiotic factors especially physical and chemical properties of soil, such as soil pH, organic carbon, EC, nutrition, temperature, soil type, moisture, etc., The management is a challenging issue due to non-availability of nematicides and also effective management practices all these factors represents, Meloidogyne graminicola a serious menace for rice production. Considering the impact of this nematode in rice production a literature is mainly focusing on distribution, symptoms, biology, survival strategies and management practices.
