“…Next, 4% sodium alginate solution was prepared using BPE, 250 mL of this solution was added to the Erlenmeyer flask (500 mL), and an equivalent amount of GYM liquid medium containing partial hyphae was then added, such that the total volume was adjusted to 500 mL. In accordance with the method of Taba et al ( 35 ), the simple mixed granular formulation (approximately 2 mm in diameter) was produced using this mixed solution. Four different formulations were produced using this method: liquid medium (GYM), BPE (stock solution, 10-fold dilution), hyphal bodies, and a mixture of BPE (stock solution, 10-fold dilution) and partial hyphae.…”

“…A number of biological methods to control plant-parasitic nematodes have been evaluated, including Pasteuria penetrans ( 41 ) and Streptomyces sp. ( 6 ), nematode-trapping fungi ( 34 , 35 ), and various plant extracts ( 5 ). Taba et al ( 32 ) isolated 18 species of nematode-trapping fungi with several capture organs on Okinawa Island and showed that their distribution varied according to vegetation and soil types.…”

“…They later evaluated the ability to trap the second-stage juveniles (J2s) of M. incognita using isolated fungi and screened a fungus exhibiting the highest capture ability ( 34 ). These studies ( 35 , 37 ) also described a combined biological and chemical approach for controlling M. incognita using a simultaneous treatment with Monacrosporium ellipsosporum and a nematicide. In addition, Taba et al ( 36 ) investigated the nematicidal activity of extracts of a weed found primarily on Okinawa Island ( Bidens pilosa var.…”

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.
