ABSTRACT
The crop loss incurred by the infestation of a wide range of nematodes is valued in billions of dollars and has posed a serious threat to global food security. The nematode affects economically important crops all over the world and incurs a significant decline in the crop yield. Management of nematodes is given consideration and different methods have been developed. Intriguing evidence suggests that the biological method to control nematode infestation is the best and viable approach. Control of nematodes by the use of biocontrol agents offers a promising substitute to the use of chemical agents and chemical-associated harmful effects. The microbes such as fungi and bacteria have the ability to reduce the nematode population and have played a vital role in decreasing the crop yield loss caused by nematodes. The development and subsequent implementation of biocontrol agents are very unpredictable and quite hectic on a large scale. The implementation of an ideal biocontrol agent requires an elaborated understanding of the mechanisms of infectivity of the antagonist against nematode populations, and meticulous exploration of the interactions among biocontrol isolates, nematode, soil microbiota, plant microenvironment, and ecological implication must be developed.
