Burrowing nematode, Radopholus similis, root-knot nematode, Meloidogyne incognita, root lesion nematode, Pratylenchus coffeae and spiral nematode, Helicotylenchus multicinctus are the major nematode pests of crops in coconut based high-density multispecies cropping system. Vermiwash at different dilutions were tested against these nematodes under in vitro conditions and were found to be deleterious to varying extent. Juvenile hatching of M. incognita was greatly inhibited by vermiwash. Undiluted vermiwash caused maximum nematode mortality and inhibition in hatching. Among four nematodes tested, M. incognita and H. multicinctus were found to be highly susceptible to vermiwash, followed by R. similis and P. coffeae.
