Passion Fruit Woodiness Virus

Commonly affects: Passiflora edulis (Passion Fruit)

Leaves develop a mottled mosaic pattern with distorted, narrowed shape, and fruit becomes hard, small, and woody with thick rind and little pulp.

Potential Causes

  1. 1A potyvirus spread primarily by aphid feeding
  2. 2Infected planting material introducing the virus from the start
  3. 3Nearby infected passionflower relatives acting as a virus reservoir

Solution Steps

  1. 1Remove and destroy infected vines — there is no cure for viral infection
  2. 2Control aphid populations aggressively since they're the primary transmission route
  3. 3Source certified virus-free planting material
  4. 4Remove wild or ornamental Passiflora relatives nearby that could harbour the virus

Prevention Tip

Buying certified virus-free plants or seed is the most reliable prevention, since the virus has no treatment once established.
