Abstract:

    Survey of the effects of the green manure, including field mustard (Brassica campestris L.), Egyptian clover (Trifolium alexandrinum L.) and hairy vetch (Vicia dasycarpa Tenore), on the survival of plant-parasitic nematodes of 42 rice field after the second crop season of 1995 were conducted 1-3 times in the central area of Taiwan. The preliminary results indicated that there were five genera of plant-parasitic nematodes, including Hirschmanniella spp., Helicotylenchus spp., Tylenchorhynchus spp. Tylenchus spp. and Meloidogyne spp., were found in the rice field, the appearance frequency were 100%, 73.8%, 76.2%, 92.9% and 19%, respectively, and the three kinds of winter green manure all could significantly reduce the survival of Hirschmanniella spp., especially in some field with high density of the nematodes, but the effects on the Helicotylenchus spp., Tylenchorhynchus spp. and Tylenchus spp. were not consistent.
