Nematicidal Activity of Natural Products against Root-knot Nematode: A Review

Phylum Nematoda is the most abundant group among the metazoans. Root-knot nematodes (Meloidogyne spp.) are a serious threat to agrarian plants worldwide. RKN is among the most predominant spp. which affects a variety of plants and vegetables. It is challenging for farmers to manage these nematodes. The usage of nematicides is an efficient means of management of plant-parasitic nematodes. The continuous use of chemical nematicides can cause augmentation in cases of nematode resistance. In order to fulfill the requirement of modern sustainable agriculture along with safe environment and human health, there is need to switch over to natural remedies to control RKNs. Lately, many research studies have been carried out to isolate product from natural resources and evaluate their nematicidal activity against these nematodes. The present review provides a summary of nematicidal activity of the naturally derived substances against Meloidogyne incognita over the past few years.
