“…Further experiments have shown that using dried plant chips and a mixture of plant parts of B. pilosa incorporated into soil were more effective to suppress nematode populations than using foliar parts. 45 These results indicate the potency of different metabolites in the plant parts of B. pilosa and their impact on the nematode behavior. Although the objective of the current study was to identify repellents for J2s from non-host plants, which has been achieved, it would be interesting to determine whether these Asteraceae-derived repellents also influence M. incognita egg hatchability.…”

Olfactory cues guide plant parasitic nematodes (PPNs) to their host plants. We tested the hypothesis that non-host plant root volatiles repel PPNs. To achieve this, we compared the olfactory responses of infective juveniles (J2s) of the PPN Meloidogyne incognita to four non-host Asteraceae plants, namely, black-jack (Bidens pilosa), pyrethrum (Chrysanthemum cinerariifolium), marigold (Tagetes minuta), and sweet wormwood (Artemisia annua), traditionally used in sub-Saharan Africa for the management of PPNs. Chemical analysis by coupled gas chromatography–mass spectrometry (GC/MS) combined with random forest analysis, followed by behavioral assays, identified the repellents in the root volatiles of B. pilosa, T. minuta, and A. annua as (E)-β-farnesene and 1,8-cineole, whereas camphor was attractive. In contrast, random forest analysis predicted repellents for C. cinerariifolium and A. annua as β-patchoulene and isopropyl hexadecanoate. Our results suggested that terpenoids generally account for the repellency of non-host Asteraceae plants used in PPN management.

“…radiata ) on the J2s of M. incognita and found that it exhibited potent activity against M. incognita and other important nematodes ( 38 ). More recently, these authors ( 39 ) proposed various methods for the agricultural control of nematodes using plant extracts. In the present study, we examined the effectiveness of combining nematode-trapping fungi and B. pilosa extracts (BPE) for controlling nematodes.…”

We tested a formulation composed of a mixture of Bidens pilosa var. radiata extract (BPE) and nematode-trapping fungi for its effects on Meloidogyne incognita. In earlier evaluations of the effects of plant extracts on the hyphal growth of 5 species of nematode-trapping fungi with different capture organs (traps), the growth of all species was slightly inhibited. However, an investigation on the number of capture organs and nematode-trapping rates revealed that Arthrobotrys dactyloides formed significantly more rings and nematode traps than those of the control. An evaluation of simple mixed formulations prepared using sodium alginate showed that nematodes were captured with all formulations tested. The simple mixed formulation showed a particularly high capture rate. Furthermore, in a pot test, although the effects of a single formulation made from the fungus or plant extract were acceptable, the efficacy of the simple mixed formulation against M. incognita root-knot formation was particularly high.

The efficacy of polyvinyl alcohol (PVA) and polypropylene (PP) film in combination with an aqueous extract of Bidens pilosa var. radiata on suppressing the activity of second-stage juveniles of Meloidogyne incognita was investigated. In in vitro tests, PVA strips ( mm ) treated with a stock solution of the plant extract showed high nematicidal activity. The control effect of PVA and PP film belts and bags, which are water soluble and insoluble, respectively, was evaluated using pot tests. While root-knot formation was suppressed when using PVA film belts and bags, no prevention of root-knotting was observed when using the PP film belts. The bags significantly reduced root-knot formation to a level that was equivalent to fosthiazate treatment. Compared to the extract-free PVA treatments, root-knot formation was suppressed when PVA bags contained . times plant extract. Thus, the control effect of the chemical and physical composition of PVA films treated with the plant extract was confirmed. Nematol. Res. ( ), -( ).
