Abstract
Plant-parasitic nematodes (PPNs) feed on plant tissues and cause yield losses in agricultural crops. Effective nematode management involves using a range of techniques, such as use of resistant crop varieties, cultural practices, use of biocontrol agent, and use of synthetic chemicals. Although chemical nematicides are general recommended practices, yet their costs, insufficient availability, and environmental considerations make them the last options in practical nematode management. Soil disinfestation treatments, primarily utilizing various forms of heat, are used by agricultural producers to reduce soilborne inoculum of crop pests. Soil disinfestation by soil solarization is a technique based on the increase of soil temperature using the sun’s radiation and the application of plastic films.This review illustrates the method and principles behind soil disinfestation for reduction of plant-parasitic nematodes.
