Root-knot nematode (Meloidogyne spp. such as Meloidogyne javanica, M. hapla and M. incognita), belongs to endoparasite, is one of the most important agricultural harmful organisms. These harmful pathogens are responsible for causing significant yield losses in a wide range of agricultural crops, mostly vegetables, especially in tropical and subtropical regions. For controlling root-knot nematode, biological control became more acceptable than any other methods for general users since it is an eco-friendly, effective, economical and non-polluting method with the environment. Moreover, biological controls were being used due to environmental awareness and changing regulation. Different types of biocontrol agents such as fungi and bacteria are being used for controlling different plant pathogens including root-knot nematodes. However, emphasizing on the application of biological agents against of root-knot nematodes (RKN) among farmers for increasing the tomato yield all over the world. This review describes the general biology of root-knot nematodes (RKN), their nature of the damage on tomato plants, and finally the current research progress in biological control by using different organisms as well as their effects on the environment.
