  • Abstract : An unknown disease was observed in 1988 for the first time on banana, an important fruit crop introduced in 1913 to Sindh, Pakistan. The disease was observed first in coastal areas of Sindh Province, then in northern areas, where it caused heavy losses. A survey of three to six fields at various locations in each of the six major banana-growing districts in July 1991 revealed that one-half of the banana plantations had been destroyed. The disease was prevalent in Thatta, Karachi, Hyderabad, Badin, and Mirpur Khas districts. Symptoms resembled those of banana bunchy top virus, including bunching and brittleness of leaves and dot-dash dark green streaks on petioles and lamina parallel to veins. The method of Wu and Su (1) was used to purify the virus, and electron microscopy detected virus particles 20-22 nm in diameter. An ELISA kit for banana bunchy top virus (Bananase-96, General Biology Corporation, Taiwan) was used to confirm the etiology. Thus, the disease was identified on the basis of symptoms, particle morphology, and serology (DAS-ELISA). 1. R. Y. Wu and H. J. Su. J. Phytopathol. 128:153, 1990.
