Abstract

Plant parasitic nematodes (PPN) known as phytonematodes pose a role causing substantial crops damage to Indonesian onion cultivation. These phytopathogens, particulary some species such as Meloidogyne spp., Pratylenchus spp., Aphelenchoides sp., and Ditylenchus sp. were reported to infect onion crops and reduced the production. These phytonematodes are leading to symptoms like stunted growth, yellowing of leaves, and bulb deformities. The non-specific symptoms of nematodes infection and their slow development make the damage unrecognized. However, infestation by nematodes can predispose plants to secondary infections by othe soil-borne pathogens, exacerbating the damage. This review examines information on plant parasitic nematodes attack Indonesian Onion Cultivation, their damage, and various approaches to control their infestations. It aims to provide updated knowledge on plant parasitic nematodes and their control management, particulary in Indonesia. The warm and humid climate of Indonesia provides an ideal environment for nematodes proliferation, further complicating management efforts. Hence, further research is essential to develop more effective and eco-fiendly management practice.
