Symptoms
Heart rot disease of pineapples is characterised by yellow-red coloured leaves that are easily pulled from the plant and white leaf bases that bear a distinct water-soaked grey-brown transverse lesion. The lesion progresses slowly from the base of the leaf to the tip. Rotting pineapple fruit tissue may also smell badly. If the pineapple plants develop root rot, aboveground symptoms include stunting and low yield.
