Sting Nematodes: How to Identify, Treat & Control Them

Sting nematodes (Belonolaimus longicaudatus) are among the most destructive nematodes of turf and sandy-soil crops, damaging even at very low populations — the number-one nematode concern on many southern-US golf courses and sports fields.

Common crops affected

How to identify it

  • Irregular, thinning, chlorotic patches that resist water and fertiliser
  • Short, stubby, dark-lesioned roots
  • Wilt and heat sensitivity; sandy soils most at risk

Recommended Vegalab solution: Nematode Control

Soil-directed Nematode Control on the label interval; because sting damages at low numbers, treat early and monitor with assays.

Results you can mention: in field testing on bermudagrass turf, Nematode Control cut a very high sting population to zero (a complete knockdown) over two applications.

Frequently asked questions

Why is sting damaging at low numbers?

It feeds externally with a long stylet that injures root tips directly, so thresholds are far lower than for most nematodes.
