“…Here, 1‐octanol, identified in the watercress leaf volatilome, showed nematicidal activity against M. incognita , with an LC 50 (382, 5 μg mL −1 ) higher than that of the commercial nematicide carbofuran (191 μg mL −1 ) . However, carbofuran has a higher toxicity to human health and the environment compared to that of 1‐octanol .…”

“…Second, the lower concentration levels of the volatile components in the emissions, which were high enough to immobilize the nematodes but not to kill them, e.g. 3‐methyl‐1‐butyl acetate failed to show nematicidal activity at 100 μg mL −1 but killed 100% of M. incognita J 2 at 275 μg mL −1 . Moreover, this compound was found in the emissions of watercress leaf macerate.…”

BACKGROUND Plants emit volatile organic compounds (VOCs) with several functions, including toxicity to plant‐parasitic nematodes (PPNs). However, the toxicity of VOCs from watercress leaves (Nasturtium officinale) and passion fruit seeds (Passiflora edulis) against PPNs has not yet been studied. RESULTS Biofumigation with watercress leaves and passion fruit seeds reduced the infectivity and reproduction of Meloidogyne incognita in tomato plants. The VOCs emitted by watercress leaves and passion fruit seeds caused immobility of M. incognita second‐stage juveniles (J2). The reduction in infectivity and reproduction of M. incognita reached 89% and 99%, respectively, when J2 were exposed to watercress VOCs. Additionally, water exposed to VOCs emitted by watercress caused 79% M. incognita J2 mortality. The volatilome of the toxic water contained 12 compounds, mainly alcohols. The emissions from watercress leaves and passion fruit seeds contained 26 and 12 compounds, respectively, according to gas chromatography–mass spectrometry analysis. The 1‐octanol occurring in watercress emissions demonstrated in vitro and in vivo nematicidal activity against M. incognita, with a lethal dose necessary to cause 50% mortality (LC50) of 382.5 μg mL−1. CONCLUSIONS Watercress leaf and passion fruit seed macerates emitted VOCs with nematicidal activity against M. incognita. The compound 1‐octanol identified in watercress emissions may be useful for the nematicide‐producing industry. © 2019 Society of Chemical Industry

“…As a positive control, the nematicide carbofuran (2,3-dihydro-2,2-dimethyl-1-benzofuran-7yl N-methylcarbamate, 98%; Sigma-Aldrich) was used at a final microtube concentration of 191 μg/ml, corresponding to its LC 50 as determined by Terra et al (2018). The final concentration of essential oil within the microtube was 307 μg/ml, which corresponded to the concentration previously shown to kill 50% of J2 (LC 50 ).…”

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.

Plant endophytes are rich in secondary metabolites and are widely used in medicine, chemical, food, agriculture, and other fields. Here, an endophytic fungus is isolated from Ginkgo biloba L. leaves and identified as Alternaria brassicae GL07 through genotypic characterizations. It can produce fruity scented volatiles. The analysis of volatile organic compounds (VOCs) was done by gas chromatography–mass spectrometry. A total of 32 components were identified; and at different culture times, the composition of VOCs was different. It had more components in the first two weeks, but a fewer components on the 21st day. More olefins, ketone, aldehyde, and alcohol were found in the growth period and more amines and esters were found in the decline period. Also, 2,5‐dihydroxyacetophenone, β‐ionone, and nonanal were found. They were the same ingredients in Ginkgo essential oils and some of them were isolated for the first time in the volatile constituents of endophytes. The antioxidant activity and whitening activities of all extracts were also evaluated. When cultured for 10 days, it had the strongest 2,2‐diphenyl‐2‐picrylhydrazyl radical (IC50, 0.56 g/L), hydroxyl radical scavenging ability (IC50, 0.47 g/L), reducing ability, and tyrosinase inhibition ability (IC50, 5.18 g/L), which may be due to a large amount of ketones and alcohols produced during the log phase. This demonstrates the potential of A. brassicae GL07 to produce bioactive compounds and to be used for perfume and cosmetic industries.
