“…Essential oils from other plants have already been shown to reduce nematode hatching (Jardim et al, 2017;Jeon et al, 2016;Oka et al, 2000). Dysphania ambrosioides essential oil also reduces the hatching of M. chitwoodi (Faria et al, 2016). The current study demonstrated a reduction in hatching of a nematode from warmer regions, M. incognita, by the action of D. ambrosioides essential oil.…”

It is known that some plant essential oils have pesticide activities. Among the 29 oils evaluated in this study, 14 showed nematicidal activities of 8 to 100% at the concentration of 1,000 μg/ml, compared with a control of 0.01 g/ml Tween 80®. At a lower concentration of 500 μg/ml, only Dysphania ambrosioides oil caused >90% mortality of second‐stage juveniles (J2) of Meloidogyne incognita. The LC50 and LC95 values for D. ambrosioides oil were 307 μg/ml and 580 μg/ml, respectively. M. incognita eggs placed in D. ambrosioides oil solutions had a significant reduction in J2 hatching compared with controls. Therefore, the oil had a toxic effect on both eggs and J2 of M. incognita. This was in contrast to nematicides on the market that act efficiently only on J2. When J2 were placed in D. ambrosioides oil at its LC50 concentration and inoculated onto tomato plants, the reduction in numbers of galls and eggs was 99.5% and 100%, respectively. Dysphania ambrosioides oil applied to the potting substrate of plants at a concentration of 1,100 μg/ml significantly reduced the number of galls and eggs of M. incognita, whereas a concentration of 800 μg/ml only reduced the number of eggs compared with the controls (Tween 80® and water). The main components of the D. ambrosioides oil detected by gas chromatography–mass spectrometry were (Z)‐ascaridole (87.28%), E‐ascaridole (8.45%) and p‐cymene (3.35%), representing 99.08% of the total oil composition. Given its nematicidal activity, D. ambrosioides oil represents an exciting raw material in the search for new bioactive molecules for the pesticide industry.

“…Our results on hatching inhibition are in agreement with those reported by Barros et al [22], who worked with EO isolated from Dysphania ambrosioides having, as a constituent, p-cymene. Additionally, EOs from other plant species, containing p-cymene and carvacrol as major constituents, have been shown to inhibit nematode hatching [20,23,24]. When hydrosol was used, the level of juveniles hatched from egg masses (58 and 49% for M. incognita and M. javanica, respectively) was lower than that observed in EO.…”

Essential oil (EO) and hydrosol (HL) isolated from an indigenous plant species Satureja hellenica were evaluated against Meloidogyne incognita and M. javanica. Particularly, the activity of extracts on a second stage juvenile’s (J2s) motility, the hatching of J2s from eggs, egg differentiation and the effect on J2s in soil were tested. A paralysis of 100% of the J2s of both species was recorded after 96 h of immersion in the essential oil, at a dose of 2000 μL/L. At the same dose, the percentage of paralyzed J2s after 48 h of immersion was more than 80%, for both Meloidogyne species. The use of hydrosol has shown encouraging results only in the dilution of 50%, where for both Meloidogyne species tested, the percentage of paralyzed J2s was more than 70% after 48 h of immersion, while the percentage was increased to 90% after 96 h of immersion. Egg differentiation was ceased after immersion, either in EO or HL. However, this decrease in egg differentiation was evident only at higher concentrations of EO and at the highest HL dilution (0.5 v/v). The hatching of M. incognita J2s was decreasing as the dose was increasing. The lowest numbers of hatched J2s were recorded at the doses of 2000 and 4000 μL/L. A clear reduction in M. javanica J2s hatching was observed as the dose was increased to 250 μL/L, a fact constantly observed as the dose was increasing up to 4000 μL/L. Lower numbers of nematodes were recorded in roots grown in infested soil after the application of EO or HL at the highest doses. The EO of S. hellenica is characterized by the presence of p-cymene (27.46%) and carvacrol (23.25%), and in a lesser extent of other constituents, such as borneol (6.79%), carvacrol methylether (6.77%), γ-terpinene (4.63%) and 4-terpineol (3.65%). Carvacrol was the major constituent found in the HL (50.12%), followed by borneol and 4-terpineol (20.42 and 6.72%, respectively).

“…The use of essential oils (EOs) is known from folk medicine centuries ago [ 8 ]. Nowadays, it seems to be a promising control strategy against different nematode plant and animal parasites ( Bursaphelenchus xylophilus , Cooperia spp., Ditylenchus dipsaci , Haemonchus contortus , Meloidogyne chitwoodi , M. incognita , M. javanica , Oesophagostomum spp., Pratylenchus penetrans , Steinernema feltiae , Trichostrongylus spp., Tylenchulus semipenetrans ) [ 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ]. Microbivorous nematodes contribute to decomposition of organic matter and the release of nutrients for plant uptake [ 24 ], which makes them important components of the soil microfauna.…”

Essential oils (EOs) have historically been used for centuries in folk medicine, and nowadays they seem to be a promising control strategy against wide spectra of pathogens, diseases, and parasites. Studies on free-living nematodes are scarce. The free-living microbivorous nematode Panagrolaimus sp. was chosen as the test organism. The nematode possesses extraordinary biological properties, such as resistance to extremely low temperatures and long-term survival under minimal metabolic activity. Fifty EOs from 22 plant families of gymnosperms and angiosperms were tested on Panagrolaimus sp. The aims of this study were to investigate the in vitro impact of EOs on the psychrophilic nematode Panagrolaimus sp. in a direct contact bioassay, to list the activity of EOs based on median lethal concentration (LC50), to determine the composition of the EOs with the best nematicidal activity, and to compare the activity of EOs on Panagrolaimus sp. versus plant parasitic nematodes. The results based on the LC50 values, calculated using Probit analysis, categorized the EOs into three categories: low, moderate and highly active. The members of the laurel family, i.e., Cinnamomum cassia and C. burmannii, exhibited the best nematicidal activity. Aldehydes were generally the major chemical components of the most active EOs and were the chemicals potentially responsible for the nematicidal activity.
