Worldwide distribution. Two viruses occur, either alone or more often together in cultivated and wild passionfruit. An important disease.
The disease causes distorted leaves and small fruits, but seriousness depends on variety and virus strains.
Spread is by aphids. The viruses are not seed borne.
Cultural control: take scions from disease-free plants, and rootstocks from seed; carefully check every plant for symptoms before field planting; avoid planting near known hosts of Cucumber mosaic virus, e.g., banana, capsicum, chilli, cucurbits; weed (i.e., wild passion flowers); plant tolerant hybrids (yellow x purple).
