“…Pure culture of M. incognita (Kofoid and White, 1919) Chitwood, 1949 raised on Celosia argentea was extracted using the method of Hussey and Baker (1973), the extracted eggs and juveniles served as source of inoculums. Approximately 1000 eggs and juveniles per ml of M. incognita were inoculated around the base of each lettuce plant (Fabiyi et al, 2019) at four days after transplanting. The crude extracts, fractions and essential oil were applied a week after inoculation at 200 ml in variants of 50, 75 and 100 mg/ml, while the dry powder leaves used as soil amendment was applied at 150, 175 and 200 g. The reference standard check was carbofuran (a synthetic Fabiyi nematicide) applied at 0.5, 1.0 and 1.5 kg/ai/ha.…”

Plant parasitic nematodes (PPNs) are acknowledged as a paramount factor which limits the production of staple crops and vegetables. Preferred standard control method had been the use of synthetic nematicides. However, owing to the undesirable consequences of the residual effect of nematicides in the environment, the need for alternative approaches becomes pertinent and this has prompted investigation into the nematicidal potential of extracts from Lawsonia inermis for practicable application on lettuce plants infected with Meloidogyne incognita in field experiments. The leaves of L. inermis were collected and divided into four parts for separate extraction and these were compared with the standard nematicide carbofuran individually. The essential oil (EO) was significantly more potent than the other extracts from L. inermis. There was no significant difference between plants treated with carbofuran and EO. The fractions were significantly better than crude methanol and ethanol extracts of L. inermis. Reproduction of M. incognita on lettuce plant roots was considerably reduced by utilization of L. inermis extracts. Notably higher vegetative growth was observed in treated lettuce plants. The IR, 1 H-NMR and 13 C-NMR spectral data analysis confirmed the presence of sesquiterpenes in the chromatographic fraction. The GC-MS profile indicated phytol as the major constituent of the EO. The results obtained from this study indicates that extracts from L. inermis could be a viable option in the management of M. incognita damaging lettuce in dependable vegetable production.

“…Root-knot nematodes (RKNs) Meloidogyne spp. are the principal PPNs which affects yield in several crops (Taniwiryonoc et al, 2009;Fabiyi, 2019;Fabiyi and Olatunji, 2021a). Largely, amidst the specie Meloidogyne incognita is a foremost pest of vegetables (Fabiyi and Olatunji, 2021b).…”
