Natural Nematode Control for Turf and Ornamental Roots

On turf, root-knot and other nematodes thin the root system that keeps stands dense and resilient, leaving irregular weak areas that struggle under heat and traffic. Sandy, high-value sports and golf soils are common trouble spots.

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 as populations build in warm soil and ahead of peak stress periods.

What to look for

  • Irregular thin, off-colour patches that resist fertiliser
  • Wilting and heat sensitivity in affected zones
  • Shallow, galled roots on inspection
  • Slow recovery from wear

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.
