Essential oils as phytochemical nematodicides with activity against plant parasitic nematodes

Abstract

Synthetic pesticides used against plant parasitic nematodes (PPNs) have been discontinued due to serious environmental and public health concerns. Essential oils (EOs) are promising alternatives given they are easily accessible, show high biological activities, have low environmental impacts, and are subjected to less strict regulatory approval mechanismsWe reviewed the chemical composition of EOs with direct biological activity against the root-knot nematodes (RKNs), plant cyst nematodes (PCNs), and the pinewood nematode (PWN). The compositions (≥10%) of the top 10 most active EOs were compared.
