Abstract

A virus of the cocoa swollen shoot group infecting cocoa in North Sumatra.

Abstract

A disease of cocoa in North Sumatra which causes leaf symptoms ranging from a clearing of the major veins to a more complex mosaic pattern was transmitted by grafting and the mealybug Planococcus citri. Bacilliform particles similar in size and shape to those of cocoa swollen shoot virus were found in preparations from diseased leaves, suggesting that the disease is induced by infection with a virus of the cocoa swollen shoot group.
