Minor Pest Title
Passion fruit woodiness potyvirus (PWV)
Minor Pest Description
A number of virus diseases have been reported, notably the passion fruit woodiness potyvirus. Affected leaves show light and dark green mosaic pattern often with light yellow speckle. Sometimes small, yellow ring spots may develop on upper leaf surface. Infected fruits are small and misshapen with very hard rind and small pulp cavity. When affected fruit is cut, the inside rind tissue may have brown spots. Some strains of the virus cause cracking of affected fruits.
They are spread by aphids (Aphis gossypii and Myzus persicae) grafting and pruning knives. The virus has a wide host range including bananas, cucurbits and many weeds.
Minor Pest What to do.
- Use virus-free planting material.
- Disinfect pruning tools with household bleach.
- Use resistant hybrids, or rootstocks of yellow passion fruit.
- Remove diseased vines from the field.
