“…Crude water extracts of Melia azedarach elicited defense responses from cucumber against Meloidogyne incognita and decreased the activities of catalase and peroxidase involved in host H 2 O 2 detoxification. Low activities of these enzymes inside the host imply the enhanced defense system of the plant (Cavoski et al, 2012). Using aqueous plant extracts of Hibiscus sabdariffa, Punica granatum and Eucalyptus globulus, Hassan et al (2009) demonstrated the elicitation of systemic resistance in potato against BW.…”

Phytobiocides are a good alternative to chemicals in managing bacterial diseases including bacterial wilt of tomato caused by Ralstonia solanacearum. In the present research study, finely ground dried powders of seven widely available medicinal plants/weeds species viz., Peganum harmala (esfand or wild rue), Calotropis procera (sodom apple), Melia azedarach (white cedar), Allium sativum (garlic), Adhatoda vasica (malabar nut), Tagetes patula (marigold) and Nerium oleander (oleander) were assessed for their anti-microbial activity, both in-vitro (10% w/v) and in-vivo (10, 20, 30, and 40 g/kg of potted soil) against R. solanacearum. Aqueous extracts (prepared as 10% w/v, soaking for 48-72 h and filtering) of C. procera, A. vasica, and T. patula inhibited the in-vitro growth of the bacterial pathogen over 60% of that produced by the standard antibiotic streptomycin. A. sativum, N. oleander and P. harmala aqueous extracts were less effective while M. azedarach showed no effect against R. solanacearum. The higher dose (40 g/kg of soil) of C. procera, A. vasica and T. patula decreased disease severity quite effectively and increased yield and plant growth characters as much as the standard antibiotic did. No phytotoxicity of medicinal plants powder was observed on tomato plants. Alkaloids, flavonoids, tannins, saponins and terpenoids were detected in the aqueous extracts of T. patula and A. vasica whereas C. procera was found to have only alkaloids, flavonoids, tannins and saponins. Our data suggest that dried powders of T. patula, C. procera and A. vasica (40 g/kg of soil) could be used as an effective component in the integrated disease management programs against bacterial wilt of tomato.

“…Additionally, such agents often act at multiple and novel target sites, thereby reducing the potential of plant-parasitic nematodes becoming resistant to them [22,23]. The nematicidal principles of plants, based on materials such as isothiocyanates, thiophenics, glucosides, alkaloids, phenolics, thianins and fatty acids, have been identified and reviewed [9,13,24,25].…”

In this study, the 3,4-dihydroxybenzoic acid (3,4-DHBA) from Terminalia nigrovenulosa bark (TNB) was purified and its in vitro nematicidal activity was investigated against Meloidogyne incognita. The purification of 3,4-DHBA used a silica gel column and Sephadex LH-20 chromatography combined with thin-layer chromatography and high performance liquid chromatography. Structural identification of the 3,4-DHBA was conducted using (1)H nuclear magnetic resonance (NMR), (13)C NMR, and liquid chromatography time-of-flight mass spectrometry. Nematicidal activity bioassays revealed that 3,4-DHBA treatment resulted in 33.3, 47.5, 72.5 and 94.2% J2 mortality at 0.125, 0.25, 0.5 and 1.0 mg/ml, respectively after 12 h incubation. J2 mortality was increased significantly (P < 0.0001) with increasing incubation time in the range of 54.2-94.2% from 3 to 9 h after incubation with 3,4-DHBA (1.0 mg/ml), but with no significant difference observed where the incubation time was increased from 9 to 12 h. The 3,4-DHBA treatment resulted in 33.3, 65.0, 76.7 and 85.0% hatch inhibition at 0.125, 0.25, 0.5 and 1.0 mg/ml, respectively, 3 days after incubation. Changes in the shape of the eggs were determined after incubation for 1 day with a 3,4-DHBA concentration of 1.0 mg/ml.

“…A scarce amount of specialized literature about insects, mites and nematodes affecting MAPs and their management is available by far, probably due to the limited cropping area and to the fact that some allelochemicals produced by many of these plants showed a repellent, antifeedant or toxic action against many pests (Regnault-Roger 1997;Isman 2000;Miresmailli et al 2006;Akhtar et al 2012;Cavoski et al 2012;Benelli et al 2012;Faraone et al 2012), leading to consider MAPs as less susceptible. Direct damages caused by pests depend mainly on their biology, but also the plant conditions, such as water stress, nutritional factors, soil and climate, may play an important role Pillonel et al 2012).…”
