“…Synthetic recommended nematicides like carbofuran, fluopyram owing to their associated detrimental effects on the environment, non-target organisms besides phytotoxicity, necessitate safer approaches for nematode management in cropping systems ( Westphal, 2011 ; Jones et al, 2017 ). To develop ecofriendly alternatives, a wide spectrum of plant metabolites with nematostatic and nematicidal actions has extensively been reported ( Atolani and Fabiyi, 2020 ).…”

Nematicidal potential of essential oils (EOs) has been widely reported. Terpenoids present in most of the essential oils have been reported responsible for their bioactivity though very less is known about their modes of action. In the present study, an in vitro screening of nine Eos, namely, Citrus sinensis (OEO), Myrtus communis (MTEO), Eucalyptus citriodora (CEO), Melaleuca alternifolia (TEO), Acorus calamus (AEO), Commiphora myrrha (MREO), Cymbopogon nardus (CNEO), Artemisia absinthium (WEO), and Pogostemon cablin (PEO) against Meloidogyne incognita revealed OEO, CNEO, and TEO as most effective with LC50 39.37, 43.22, and 76.28 μg ml–1 respectively. EOs had varying compositions of mono- and sesquiterpenes determined by gas chromatography-mass spectrometry (GC-MS) analysis. The in silico molecular interactions screening of major EO constituents and the seven selected target proteins of the nematode indicated highest binding affinity of geraniol-ODR1 (odorant response gene 1) complex (ΔG = -36.9 kcal mol–1), due to extensive H-bonding, hydrophobic and π-alkyl interactions. The relative binding affinity followed the order: geraniol-ODR1 > β-terpineol-ODR1 > citronellal-ODR1 > l-limonene-ODR1 > γ-terpinene-ODR1. Taken together, the cumulative in vitro and computational bioefficacy analysis related to the chemoprofiles of EOs provides useful leads on harnessing the potential of EOs as bionematicides. The insight on biochemical ligand–target protein interactions described in the present work will be helpful in logical selection of biomolecules and essential oils for development of practically viable bionematicidal products.

The study involves evaluation of two nematicides, namely Turtob-F (a new nematicide) and carbofuran on 3 nematode populations and two bacteria associated with the rhizosphere of brinjal. The effect of the nematicides was observed on the population size of the selected nematodes and bacteria as well as the yield of brinjal crop. All three nematode populations were markedly reduced by the applied nematicides. The bacterial populations (Pseudomonas and Klebsiella) however, remained uninfluenced by the nematicides. The yield of brinjal was found to be significantly elevated (p<0.05).

“…The present study shows that the population of M. incognita recovered after harvest was significantly lower (73.75/200 cc) in treatment where a combination of 3 amendments (chicken manure + neem cake + neem leaves) were incorporated into the soil than the treatments, where 2 amendments [neem cake + neem leaves (111.25/200 cc); chicken manure + neem leaves (131.25/ 200 cc); chicken manure + neem cake (168.75/200 cc)] were added to the soil. The use of organic amendments is effective and environmentally safe management of plant-parasitic nematodes and many other crop pests and pathogens (Atolani and Fabiyi 2020). Various organic amendments release nematoxic compounds such as organic acids, nitrogenous compounds like ammonia, or various plant secondary metabolites during their decomposition (Rodriguez-Kabana et al 1987;Akhtar and Malik 2000).…”

Background Organic amendments are well known for influencing soil nematode community structure, diversities, and activities. Most of the previous studies focused on effects of organic amendments on plant-parasitic nematodes, but only a few investigated the effect of combination of biocontrol agents and organic amendments on soil nematodes. Main body Different organic amendments (neem cake, poultry manure, and neem leaves) were combined with the predatory nematode, Fictor composticola, for the control of root-knot nematode, Meloidogyne incognita, in cucumber. Organic amendments were mixed in pots containing 1 kg soil, 15 days before sowing. Cucumber (cv. CCH-1) plants grown in these pots were inoculated by 2000 J2 of M. incognita and 400 F. composticola per pot, after 1 week of germination. Fictor composticola in combination with chicken manure + neem cake + neem leaves was found the best mixture for reducing the number of galls, egg masses, and final root-knot nematode population. The predator’s population reached the maximum in this treatment. All combinations of organic amendments in the presence of F. composticola were found significantly superior over inoculated check in reducing nematode’s population and in improving plant growth over the un-inoculated check. Conclusions Data indicated the suitability of using the predatory nematode, F. composticola, and organic amendments for potential use in sustainable nematode management strategies.
