Root-Knot Nematodes on Kiwi Vines

Commonly affects: Actinidia deliciosa, A. chinensis (Kiwi)

The vine shows general decline and reduced vigour despite adequate care. Roots, when examined, show small knotted galls along their length.

Potential Causes

  1. 1Root-knot nematodes feeding on root tissue and forming galls
  2. 2Sandy soil, which nematodes move through and colonise easily
  3. 3Continuous planting in infested soil

Solution Steps

  1. 1Improve soil organic matter to support beneficial, nematode-suppressing soil organisms
  2. 2Solarise soil with clear plastic over a hot summer before replanting in severely infested areas
  3. 3Choose nematode-resistant rootstock where grafted plants are available
  4. 4Avoid moving soil from infested areas to clean planting sites

Prevention Tip

Building healthy, organic-matter-rich soil supports the beneficial organisms that naturally suppress nematode populations over time.
