Nematodes are microscopic microorganisms that parasitize the roots of vegetable crops, resulting in significant yield losses and quality reduction. Chemical nematicides are often ineffective, expensive, or harmful to the environment and human health. Therefore, there is a need for alternative and sustainable methods to manage nematode infestations. One such method is the use of beneficial microbes, such as bacteria, fungi, and actinomycetes, that can suppress, repel, or kill nematodes by various mechanisms. This chapter reviews current knowledge on the diversity, ecology, and application of beneficial microbes for nematode control in vegetable crops. It also discusses the challenges and opportunities for improving the efficacy and consistency of microbial biocontrol agents in the field.
