  • To speed up the extract of endoparasitic nematodes from roots, four extraction methods with or without root-grinding were compared; 1) immersion, 2) immersion + Air, 3) Oostenbrink dish, and 4) Mistifier. The experiments were conducted for nine days by using perilla roots infested with Pratylenchus vulnus. Root-lesion nematodes continuously extracted from perilla roots during the experiments and as much as 3-10% in 9th days. The total number of nematodes extracted from 2 g of perilla root in nine days were varied among methods (379-1,824 nematodes); the most nematodes were extracted by root grinding + immersion + air (1,824) and the root-grinding + mistifier method (1,349) (p = 0.05). In the first two days of extraction, root-grinding + mistifier extracted the most nematodes (725 nematodes), followed by root-grinding + immersion + Air (555 nematodes), and root-grinding + Oostenbrink dish (421 nematodes). Root-grinding effected as much as 16-108% more nematodes extraction when compared to without root-grinding (p = 0.01).
