“…For example, Eupatorium adenophorum Spreng (synonym: Ageratina adenophora (Spreng.)) has been gradually recognized as an anti-nematode and insecticide agent in recent years and it belongs to the Asteraceae family [13,14]. This bio-fumigant has diverse groups of secondary metabolites, including monoterpenes, sesquiterpenes, diterpenes, triterpenes, flavonoids, polysaccharides, pyrrolizidine alkaloids, and phenylpropanoids [15].…”

Meloidogyne spp. are important parasitic nematodes affecting a variety of plants worldwide. We investigated the nematicidal properties of specific compounds found in bio-fumigant plants, particularly linalool, nonanal, methylene chloride, and 2-Decanal. Laboratory findings revealed that methylene chloride and 2-Decenal effectively reduced populations of second-stage juveniles (J2s). Additionally, the research explored the effects of tomato (Solanum lycopersicum L.) on M. incognita J2s, observing that tomato leaves significantly increased J2 mortality for all time measurements and different temperatures, while the opposite results were observed for root-stems. In the study, leaf treatment resulted in a maximum mortality response (MRmax) and half-maximal effective concentration (EC50) of approximately 100% and 4.0 µg/mg, respectively, at a temperature of 35 °C by week 8. In contrast, the root-stems treatment showed an MRmax of 13.5% and an EC50 of 3.0 ± 1.7 µg/mg. GC-MS analysis identified key compounds in tomato leaves and root-stems, such as α-pinene, d-limonene, and linalool. The results suggest that tomato leaves have potential as effective bio-fumigants for controlling root-knot nematodes.
