“…The most effective concentration of liquid chitosan in vitro was found to be 2%, and the suppressive effect of J2 hatching from egg, egg mass and J2 mortality was determined as 73.9%, 78.6% and 74.0%, respectively. Khan et al (2021) reported that chitosan caused 100% mortality of J2s within 36 h while Seo et al (2014) also stated that chitosan caused J2 mortality approximately 95.8% after 48 h. The nematicidal effect of 2% liquid chitosan was similar to the nematicide Velum in vitro. This result shows that the liquid chitosan application is promising for controlling root knot nematodes.…”

“…Chitosan combined with onion waste effectively controlled root-knot nematode disease and improved plant growth as well as the yield of eggplant (Ashif et al, 2017). In combination with botanicals (Argemone mexicana L., Achyranthes aspera L., and Ricinus communis), chitosan showed a synergistic effect against M. incognita on carrot as compared to chitosan alone (Khan et al, 2021).…”

The present study investigated to evaluate the potential of liquid chitosan of three concentrations (0.5, 1 and 2%) on Meloidogyne incognita (Kofoid and White, 1919) Chitwood, 1949 in vitro and on tomato under controlled conditions ((24 ± 1 °C, 60 ± 5% humidity). In vitro assay, the effect of the liquid chitosan concentrations on suppressing of hatching from eggs and second juvenile larvae (J2) mortality was determined. The reducing effect of the concentrations on the number of gall and egg mass on tomato roots and the J2 density in the soil was evaluated under controlled conditions. All concentrations suppressed hatch and increased J2 mortality more than control in vitro. The most effective concentration was found at 2% in vitro and its nematicidal effect on egg and J2 was over 70%. The results demonstrated that 0.5, 1 and 2% concentrations were significantly decreased gall/root, egg mass/root and J2 in soil compared to negative control under controlled conditions. No statistically significant difference was found between the nematicidal effects of the concentrations on the gall and egg mass (P≤0.05). It has been determined that 1 and 2% concentrations better suppress the J2 in soil than 0.5%. Although the nematicidal effect of 2% concentration was high in vitro and under controlled conditions, it was determined that it negatively affected plant biomass. Also, only 1% concentration of chitosan application controlled M. incognita on tomato by 58%. The present results show that the use of 1% liquid chitosan concentration against M. incognita will be more effective.

“…trategies have been developed to manage root-knot nematodes which includes cultivar resistance (Khan et al, 2018;Asif et al, 2018), organic soil amendments (Khan et al, 2019;Khan et al, 2021), biocontrol agents (Huang et al, 2014). The use of resistant cultivars provide an efficient and environment-friendly safety check to reduce the nematode population (Changkwian et al, 2019).…”

Aim: The present study was conducted to identify the resistance and susceptibility of beetroot cultivars against root-knot nematode, Meloidogyne javanica. Methodology: In this study, seven beetroot cultivars were screened against the root-knot nematode, Meloidogyne javanica, at the inoculum level of 1500 second-stage juveniles (J2s) per pot. Five replications of each cultivar of beetroot were used for screening and kept in a completely randomized design (CRD) at 25 ± 2 °C under greenhouse conditions. The data were subjected to ANOVA using SPSS-17 statistical software (SPSS Inc., Chicago, IL, USA). According to Duncan’s Multiple Range Test, the mean values were statistically compared and separated at P ≤ 0.05. Results: The results revealed that all seven cultivars of beetroot showed varying degrees of resistance and susceptibility to M. javanica. Among all the cultivars, three were moderately resistant, i.e., CG, DDR and Red Ace with the minimum number of galls (4.0, 8.0 and 7.0), and two were moderately susceptible, i.e., Atlas and Red Queen (28 and 22). Red Ruby (84) was found susceptible and Red Express was highly susceptible with the maximum galls (126). None of the cultivars were found to be highly resistant or immune. Interpretation: A positive and significant correlation was found between the number of galls and per cent reduction in plant growth parameters. From the results, it can be recommended that the use of resistant cultivars is an environment-friendly approach that can be used to manage the nematode density below the economic threshold level.

“…Hence, there is an ever-increasing need to search for safer and eco-friendly nematicides to prevent PWN infection [ 8 , 9 ]. A broad spectrum of bioactive plant secondary metabolites, generated by plants to resist attackers over their lifetime, have been screened for their use as pesticides or model compounds for chemically synthesized derivatives with enhanced insecticidal activity and eco-friendliness [ 12 , 13 ], and a significant number of studies have focused on phytochemical-based strategies for nematode control [ 14 , 15 , 16 ]. To date, a growing number of nematicidal phytochemicals used against PWN have been evaluated as potential nematicides for PWD management and include plant essential oils, alkaloids, coumarins, flavonoids, and glycosides [ 3 , 17 ].…”

Nematicidal Coumarins from Cnidium monnieri Fruits and Angelica dahurica Roots and Their Physiological Effect on Pine Wood Nematode (Bursaphelenchus xylophilus)

et al. 2023

Pine wood nematode (PWN), Bursaphelenchus xylophilus, is a major pathogen of pine wilt disease (PWD), which is a devastating disease affecting pine trees. Eco-friendly plant-derived nematicides against PWN have been considered as promising alternatives to control PWD. In this study, the ethyl acetate extracts of Cnidium monnieri fruits and Angelica dahurica roots were confirmed to have significant nematicidal activity against PWN. Through bioassay-guided fractionations, eight nematicidal coumarins against PWN were separately isolated from the ethyl acetate extracts of C. monnieri fruits and A. dahurica roots, and they were identified to be osthol (Compound 1), xanthotoxin (Compound 2), cindimine (Compound 3), isopimpinellin (Compound 4), marmesin (Compound 5), isoimperatorin (Compound 6), imperatorin (Compound 7), and bergapten (Compound 8) by mass and nuclear magnetic resonance (NMR) spectral data analysis. Coumarins 1–8 were all determined to have inhibitory effects on the egg hatching, feeding ability, and reproduction of PWN. Moreover, all eight nematicidal coumarins could inhibit the acetylcholinesterase (AChE) and Ca2+ ATPase of PWN. Cindimine 3 from C. monnieri fruits showed the strongest nematicidal activity against PWN, with an LC50 value of 64 μM at 72 h, and the highest inhibitory effect on PWN vitality. In addition, bioassays on PWN pathogenicity demonstrated that the eight nematicidal coumarins could effectively relieve the wilt symptoms of black pine seedlings infected by PWN. The research identified several potent botanical nematicidal coumarins for use against PWN, which could contribute to the development of greener nematicides for PWD control.
