“…The flavone-C-glycoside, lantanoside, exhibited 90% mortality within 24 h at a concentration of 1% against M. incognita (Chitwood, 2002). Two glycosides (schaftoside and isoschaftoside) isolated from ethanolic extracts of tubers of Arisaema erubescensi possessed strong nematicidal activity against M. incognita (Du et al, 2011). The results of the present in vitro study were further strengthened by complementary data obtained from in planta experiments, where the application of root and stem extracts significantly decreased the parameters of nematode parasitism (number of galls, galling index, egg masses g )1 , eggs g…”

In vitro and in planta nematicidal activity of Fumaria parviflora (Fumariaceae) against the southern root‐knot nematode Meloidogyne incognita

Root and stem extracts of Fumaria parviflora showed strong nematicidal activity against Meloidogyne incognita in in vitro and in planta experiments. Phytochemical screening of F. parviflora revealed the presence of seven classes of bioactive compounds (alkaloids, flavonoids, glycosides, tannins, saponins, steroids and phenols). Quantitative determination of the plant extracts showed the highest percentages of alkaloids (0AE9 ± 0AE04) and saponins (1AE3 ± 0AE07) in the roots and total phenolic contents in the stem (16AE75 ± 0AE07 lg dry g)1). The n-hexane, chloroform, ethyl acetate and methanol extracts of roots and stems at concentrations of 3AE12, 6AE24, 12AE5, 25AE0 and 50AE0 mg mL , significantly inhibited hatching and increased mortality of second-stage juveniles (J2s) compared with water controls. Percentage J2 mortality and hatch inhibition were directly related to exposure time. In pot trials with tomato cv. Rio Grande, root and stem extracts at concentrations of 1000, 2000 and 3000 ppm, applied as soil drenches, significantly reduced the number of galls, galling index, eggs masses, eggs and reproduction factor compared with the water control. Regardless of concentration, all the extracts significantly increased the host plant growth parameters studied. The n-hexane extracts from the roots and stem were the most active, followed by the methanol ones, at all concentrations. The in vitro and in planta results suggest that extracts from the roots and stem of F. parviflora may be potential novel nematicides.

“…Studies of mutant lines (Jones et al 2007) showed that flavonoids are definitely produced as part of the defense response to nematode infection but are unlikely to be an integral component of the mechanisms used by nematodes to induce feeding sites. Recently, Du et al (2011) isolated and identified two flavonones-C-glycosides, schaftoside and isoschaftoside, from the extract of Arisaema erubescens (Wall.) with strong nematicidal activity against the root-knot nematode Meloidogyne incognita.…”

Plant-borne flavonoids released into the rhizosphere: impact on soil bio-activities related to plant nutrition. A review

et al. 2012

Plants produce and release in the surrounding soil, the so-called rhizosphere, a vast variety of secondary metabolites. Among them, flavonoids are the most studied, mainly for their role in the establishment of rhizobiumlegume symbiosis; on the other hand, some studies highlight that they are also important in the plant strategies to acquire nutrients from the soil, for example, by acting on its chemistry. The scope of this review is to give a quick overview on the types and amounts of plant-released flavonoids in order to focus on their effects on soil activities that in turn can influence nutrient availability and so plant mineral nutrition; emphasis is given to the different nutrient cycles, soil enzyme, and soil bacteria activities, and their influence on soil macrofauna and roots of other plants. Finally, the possible outcome of the climate change on these processes is discussed.
