INTERACTION OF MELOIDOGYNE INCOGNITA AND PHYTOPHTHORA PALMIVORA ON BETELVINE

Abstract

Experiments were conducted for two years to study the interaction between Meloidogyne incognita and the wilt fungus Phytophthora palmivora on Piper betle. Synergistic interaction occurred between nematode and fungal pathogens on the crop, both in concomitant and sequential inoculations of the nematode and fungus. Increase in vine mortality was observed when the nematode inoculation preceded the fungus.
