Since 1982 melon plants cv. Galia grown in plastic houses showed severe leaf and stem necrosis. A virus isolated from affected plants infected only Cucurbitaceae . Systemic infections were only developed in melon and Luffa acutangula , while a severe hypocotyl necrosis was observed in watermelon. Purified virus sedimented in sucrose gradients as a single component and reacted only with antisera to melon necrotic spot virus (MNSV). Seed transmission (22.5%) of the virus was observed m melon plants grown from seed of naturally infected melons, but the virus could not be detected in triturated seeds. The virus could be isolated from leachate of contaminated soil and melon plants became infected when grown in contaminated soil or when watered with suspensions of virus. These properties suggest that the virus is an isolate of MNSV.
