A Mosaic Disease of Hibiscu s Manihot in Papua and New Guinea.

Abstract

Hibiscus manihot, in most areas of Papua and New Guinea, exhibits mosaic leaf symptoms induced by a virus. The virus is transmitted mechanically to H. esculentus, H. sabdariffa, H. tuberculatus, H. pungens, and H. cannabinus. The virus could not be transmitted by Planococcus citri, Freesiana sp, an aleurodid (Bemisia tabaci), nor nymphs and adults of Aphis gossypii and Myzus persicae.
