Emerging strategy for eco-friendly management of black pepper root-knot nematodes

Abstract

Black pepper (Piper nigrum L.) is one of the most important industrial crops with high economic value. This crop is cultivated in Viet Nam, Indonesia, India, and Brazil. Of these, Viet Nam is the largest producer and exporter of peppercorns in the world. However, the cultivation of this plant has faced various pathogen diseases, including the root-knot nematodes (RKNs) causing the effect on quality and productivity of peppercorns. Many methods have been investigated for controlling and preventing this disease. The number of studies on screening and utilization of beneficial microbes for the effective treatment of RKNs has increased and is also recognized as an emerging research topic. Recently, various RKNs-related reviews have been reported. However, there are only a few overview papers concerning the eco-friendly management of black pepper RKNs via using beneficial microbes and secondary metabolites. This review extensively presents, discusses and emphasizes the significant research results concerning this novel strategy for the effective management of black pepper RKNs, as well as future studies in this direction. This review provides complete scientific information which may be useful for further investigation of sustainable cultivation of black pepper crops.
