Dried plant methanol extract presented higher nematicidal activity than fresh plant extracts with an EC<jats:sub>50<\/jats:sub> = 62.6 \u00b1 26.0 and 40.8 \u00b1 26.1 \u03bcg\/ml after 48 and 72 hours of immersion, respectively. GC-MS analysis showed the presence of 17 aldehydes, with salicylaldehyde (<jats:italic>o<\/jats:italic>-hydroxybenzaldehyde) being the most abundant at 16%. Nematicidal activity of the latter and other aldehydes with chemical similarities was then assessed. The most active aldehyde was <jats:italic>o<\/jats:italic>-hydroxybenzaldehyde followed by <jats:italic>m<\/jats:italic>-hydroxybenzaldehyde, <jats:italic>p<\/jats:italic>-hydroxybenzaldehyde and benzeneacetaldehyde with an EC<jats:sub>50<\/jats:sub> of about 11.0 \u00b1 1.0, 31.0 \u00b1 22.0, 75.0 \u00b1 23.0 and 168.1 \u00b1 52.3 \u03bcg\/ml after 1 day of immersion, respectively. Position 2 of the hydroxyl group in the benzene ring seems to be very important for the nematicidal activity, followed by positions 3 and 4. As a complementary experiment, synergistic activity was observed when we added o-hydroxybenzaldehyde to m-hydroxybenzaldehyde and to p-hydroxybenzaldehyde with an EC<jats:sub>50<\/jats:sub> after 24 hours of immersion of 8.0 \u00b1 2.5 and 6.1 \u00b1 2.3 \u03bcg\/ml, respectively. Antioxidant activity assessment showed that this latter is inversely proportional to nematicidal activity. Our results showed that <jats:italic>F. esculentum<\/jats:italic> and its major compound salicylaldehyde could be integrated into the pest management system.<\/jats:p>","DOI":"10.1017\/s0022149x23000457","type":"journal-article","created":{"date-parts":[[2023,7,26]],"date-time":"2023-07-26T08:25:14Z","timestamp":1690359914000},"source":"Crossref","is-referenced-by-count":5,"title":["Nematicidal activity of <i>o<\/i>-hydroxybenzaldehyde from common buckwheat methanol extract on <i>Meloidogyne incognita<\/i>"],"prefix":"10.1017","volume":"97","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8485-4692","authenticated-orcid":false,"given":"N.","family":"Aissani","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.","family":"Aissani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F.","family":"Zouidi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H.","family":"Sebai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2023,7,26]]},"reference":[{"key":"S0022149X23000457_r17","unstructured":"Przybylski, R , Woodward, L , Eskin, NAM , Malcolmson, LJ , and Mazza, G (1995) Effect of buckwheat storage and milling on flavor compounds.
