Citrus Nematodes: How to Identify, Treat & Control Them

The citrus nematode (Tylenchulus semipenetrans) causes “slow decline” of citrus worldwide, feeding semi-endoparasitically on roots so trees gradually lose vigour, fruit size and yield.

Common crops affected

How to identify it

  • Slow general decline: smaller canopy, reduced yield
  • Dirty, encrusted roots
  • Symptoms build over years

Recommended Vegalab solution: Nematode Control

Soil drench to the root zone and drip line on the label interval, paired with balanced citrus nutrition.

Results you can mention: a primary citrus target for Nematode Control; Valencia orange field trials recorded increased tree vigour on treated trees.

Frequently asked questions

How is it different from burrowing nematode?

Citrus nematode causes slow general decline; burrowing nematode causes the more aggressive spreading decline — both are Nematode Control targets.
