Abstract


Rotylenchulus reniformis and Phytophthora palmivora were shown to interact synergistically on betelvine (Piper betle) cv. Karpoori. The incidence of wilt disease as measured in terms of root rot index was significantly higher when the nematode and fungus were inoculated concomitantly or sequentially. Vine mortality increased significantly both when nematode inoculation preceded fungal inoculation and when both pathogens were inoculated concomitantly.
