“…The percentages of dead/paralyzed nematodes observed in the microplate assays after 24 h were corrected by eliminating the natural death/paralysis (about 3%) in negative control according to the Schneider-Orelli formula (Ntalli et al, 2011): Adjusted mortality (%) = (Mortality in treatment -Mortality in negative control) ÷ (1 -Mortality in negative control) × 100…”

Macleaya cordata R. Br. is a source of bioactive compounds which are used in phytopreparations with anti-inflammatory and antimicrobial activities. In this study, four isoquinoline alkaloids were isolated from the crude alkaloid extract of the aerial parts of M. cordata, and were identified as sanguinarine, chelerythrine, protopine and allocryptopine. These alkaloids were screened for their nematicidal activity against the nematodes Bursaphelenchus xylophilus, Caenorhabditis elegans and Meloidogyne incognita. Three alkaloids, sanguinarine, chelerytherine and allocryptopine, showed nematicidal activity with the median lethal concentration (LC 50 ) values as 28.52, 34.50 and 37.45 µg/ml, respectively, against B. xylophilus; 22.78, 40.25 and 38.90 µg/ml, respectively, against C. elegans; and 67.52, 61.00 and 76.56 µg/ml, respectively, against M. incognita at 24 h. This is the first report on the nematicidal activity of the alkaloids from M. cordata against the nematodes, B. xylophilus, C. elegans and M. incognita.

“…Other monoterpenes revealed a hierarchy of functional groups, phenols, aldehydes and primary alcohols being the most active followed by secondary and tertiary alcohols. Ntalli et al (2011b) analyzed the synergistic and antagonistic interactions between components from EOs active against Meloidogyne incognita, showing that combinations of nematicidal EO components, such has carvacrol/thymol or carvacrol/geraniol, had a synergistic activity on M. incognita J2 juvenile paralysis.…”

Bioactivity against Bursaphelenchus xylophilus: Nematotoxics from essential oils, essential oils fractions and decoction waters

a b s t r a c tThe Portuguese pine forest has become dangerously threatened by pine wilt disease (PWD), caused by the pinewood nematode (PWN), Bursaphelenchus xylophilus. Synthetic chemicals are the most common pesticides used against phytoparasitic nematodes but its use has negative ecological impacts. Phytochemicals may prove to be environmentally friendly alternatives. Essential oils (EOs) and decoction waters, isolated from 84 plant samples, were tested against B. xylophilus, in direct contact assays. Some successful EOs were fractionated and the fractions containing hydrocarbons or oxygen-containing molecules tested separately. Twenty EOs showed corrected mortalities P96% at 2 lL/mL. These were further tested at lower concentrations. Ruta graveolens, Satureja montana and Thymbra capitata EOs showed lethal concentrations (LC 100 ) < 0.4 lL/mL. Oxygen-containing molecules fractions showing corrected mortality P96% did not always show LC 100 values similar to the corresponding EOs, suggesting additive and/or synergistic relationships among fractions. Nine decoction waters (remaining hydrodistillation waters) revealed 100% mortality at a minimum concentration of 12.5 lL/mL. R. graveolens, S. montana and T. capitata EOs are potential environmentally friendly alternatives for B. xylophilus control given their high nematotoxic properties. Nematotoxic activity of an EO should be taken in its entirety, as its different components may contribute, in distinct ways, to the overall EO activity.

RESUMO: O controle de fitonematóides é uma tarefa difícil. A alta infestação de nematoides no solo obriga os produtores a usarem doses mais elevadas de nematicidas, ou ainda, a aumentarem a freqüência das aplicações, geralmente no solo, ocasionando maior potencial de dano ao homem e ao ambiente. Além disso, nematicidas convencionais vêm sofrendo grandes restrições de uso em muitos países. Desse modo, a busca de novas medidas de controle de fitonematóides é uma prioridade da agricultura sustentável. Desta forma, objetivou-se estudar o efeito de óleos essenciais de Lippia Alba, na mortalidade de juvenis pré-parasitas do segundo estádio de Meloidogyne incognita. O ensaio foi montado em delineamento inteiramente casualizado, com 4 repetições, em esquema fatorial 3×4 (3 quimiotipos x 4 concentrações) empregando-se três diferentes quimiotipos de L. Alba (I, II, III) nas concentrações de 0, 100, 500 e 1000 ppm, coletados em diferentes horas do dia (7, 9, 13, 16 e 19h ABSTRACT: Antagonist activity of the essential oil Lippia alba (Mill.) N. E. Brown (Verbenaceae) on Meloidogyne incognita (Kofoid & White) Chitwood. The control of nematodes is difficult. The high infestation of nematodes in the soil requires the producers use higher doses of nematicides, increasing the frequency of applications, usually in soil, causing negative effects to humans and the environment. Furthermore, conventional nematicides have suffered great use restrictions in many countries. Thus, the search for new measures to control nematodes is a priority of sustainable agriculture. Thus, the objective of this study was available the effect of essential oils from Lippia Alba against Meloidogyne incognita. The experiment was conducted in a completely randomized design with four replications in a factorial 3x4 (3 chemotypes and 4 concentrations) using three different chemotypes of L. Alba (I, II, III) at concentrations of 0, 100, 500 and 1000 ppm, collected in different times of day (7 AM, 9 AM, 1 PM, 4 PM e 7 PM). The data collected (% mortality) were subjected to analysis of variance and mean values were compared using the Tukey test. It was able to conclude that L. alba contains in its essential oil, compounds with significant effects on mortality of M. incognita. Thus, it is important to note that the greatest nematicide effect of essential oil of L. alba suggests the possibility of its use to control M. incognita.
