Performance of volatiles emitted from different plant species against juveniles and eggs of Meloidogyne incognita

Volatile emissions of watercress (Nasturtium officinale) leaves and passion fruit (Passiflora edulis) seeds against Meloidogyne incognita

“…Plant residues are used to control PPNs, primarily through their incorporation into the soil . At the same time, the search for new compounds with nematicidal activity in plant residues has attracted the interest of several researchers …”

“…Some volatile organic compounds (VOCs) show higher nematicidal activities, e.g. exposure of M. incognita second‐stage juveniles (J 2 ) to 3‐methylbutyl acetate at 500 μg mL 1 for 1 h caused mortality above 84% . In recent years, studies on the use of plant VOCs against PPNs have expanded .…”

“…5 At the same time, the search for new compounds with nematicidal activity in plant residues has attracted the interest of several researchers. 6,7 Passion fruit (Passiflora edulis) is mostly cultivated for juice production, and thousands of tons of residues, including fruit peels and seeds, are discarded. 8,9 The toxicity of passion fruit against PPNs is still unknown, but the oil from its seeds has known antifungal properties.…”

“…exposure of M. incognita second-stage juveniles (J 2 ) to 3-methylbutyl acetate at 500 μg mL 1 for 1 h caused mortality above 84%. 7,13 In recent years, studies on the use of plant VOCs against PPNs have expanded. 6,7,[14][15][16] Biofumigation, consisting of the incorporation of plant residues that slowly release their bioactive compounds into the soil, has been successfully used to control PPNs since the 19th century.…”
