Essential Oils and Volatiles as Nematodicides against the Cyst Nematodes Globodera and Heterodera

The cyst nematodes of the genera Heterodera (HET) and Globodera (GLO) are among most damaging obligate plant parasitic (PPNs) that parasitize cereals, rice, potatoes soybean. In absence resistant crops, soil fumigation pesticides provides a good strategy for population control. However, synthetic nematicides can cause negative environmental public health impacts feared to lead development resistance immunity. use essential oils (EOs) could be viable environmentally friendly alternative, which has been poorly explored on but shown very results other PPNs. present work reviews existing bibliography biological activity EOs against GLO HET. from Allium sativum, Eucalyptus globulus, Salvia officinalis were active egg hatching. extracted Hyssopus cuspidatus, Kaempferia galanga, Menthacanadensis, Ocimum basilicum, Valeriana amurensis had highest HET J2 juveniles. Ethyl p-methoxycinnamate, phenylpropanoid ester, was EO volatile with toxicity HET, showing lower EC50 values than nematodicide fosthiazate. study is still preliminary in comparison Future works must expand this line research explore greener practices nematode pest management.
