Nematicidal properties of some indigenous plant materials against root-knot nematodes, Meloidogyne incognita on tomato Goswami B.K., Vijayalakshmi K. Abstract Pot culture and in-vitro studies were conducted simultaneously for testing nematicidal properties of Andrographis paniculata, Calendula officinalis, Enhydra fluctuans and Solanum khasianum against root-knot nematode, Meloidogyne incognita. Pot trial was done on tomato. For in-vitro studies, for one trial the percentagemortality of larvae of M. incognita was recorded while for the other, larvalhatch from egg masses was observed. All the plant materials reduced galls and nema tode populations in pot trial, C. officinalis and E. fluctuans being more effective. In invitro test also the same materials were more effective in killing larvae (larval mortality) and inhibiting hatching. Top Key words Meloidogyne incognita, tomato, plant material. Top | |
