Nematicidal Effects of Volatile Organic Compounds from Microorganisms and Plants on Plant‐Parasitic Nematodes

Abstract

Plant‐parasitic nematodes (PPNs) are one of the most destructive plant pathogens world-wide, and controlling them is extremely challenging. Volatile organic compounds (VOCs), which naturally exist in plants and microorganisms, play an important role in the biological control of PPNs and are considered potential substances for the development of commercial nematicides. This paper summarizes the VOCs produced by microorganisms and plants as well as their toxic effects on PPNs. VOCs from 26 microbial strains and 51 plants that are active against nematodes from over the last decade were reviewed. Furthermore, the mechanisms of toxicity of some VOCs against PPNs are also illustrated.
