Root-Knot Nematode Control in Strawberry

In strawberry, root-knot nematodes weaken the root system that sustains a long fruiting season, so plants lose vigour and berry size tapers off as demand peaks. Perennial and matted-row systems that stay in ground for years are particularly exposed.

Common crops affected

Why it matters

Galled roots can't feed the plant — stunting, wilting, and yield loss follow, and the wounds invite secondary soil pathogens. Nematodes are hard to eradicate once established, so early, targeted control protects the crop and the soil.

When to act

Treat at planting and early establishment; in perennial systems, manage between seasons.

What to look for

  • Weak, low-vigour plants in patches
  • Galled, stubby roots with poor branching
  • Declining berry size and runner production
  • Drought-like stress under normal irrigation

How to manage it

  1. Rotate with non-host or resistant crops in known hot spots.
  2. Build organic matter and soil biology.
  3. Use clean transplants; sanitise tools and avoid moving infested soil.
  4. Apply Nematode Control via soil irrigation, before or at planting and where infestation exists.
