Trap Cropping as a Viable Management Option for Plant-parasitic Nematode Problem: A Review

Abstract

Plant-parasitic nematodes (PPNs) causes plant damage leading to a considerable yield loss in agricultural crop throughout the world. Plant-parasitic nematodes differ in mode of feeding like endo-parasite, semi-endoparasite and ecto-parasite. Root-knot nematodes and cyst nematodes rank as the most significant species economically because of their complex interactions with host plants, extensive host range, and the extent of damage caused by infection. Successful nematode management requires a variety of approaches, including resistant crop varieties, cultural practices, biological control methods, and chemical treatments. While chemical nematicides are often recommended, their expenses, limited availability, concerns for human health, and environmental factors position them as the least favorable choice in effective nematode management. Cultural practices involve altering the cropping system and soil management that reduces nematode populations. Among all the cultural management, trap cropping is an important method for controlling plant-parasitic nematodes. This review illustrates the method and principles behind trap cropping for reduction of plant-parasitic nematodes.
