  • No restrictions in use and no re-entry interval
  • No concerns for residue runoff
  • Compatible with many soil-applied pesticides
  • Best service, product support and assurance from the market leader in terms of utilisation, application and timing

Why Nemasys J?

Nemasys® J is a biological control product containing nematodes, which effectively controls young leatherjackets, which are larval stages of craneflies (Tipula spp.), in turfgrass. Feeding damage to the turf roots is prevented. It is compatible with IPM (Integrated Pest Management) systems. Nemasys® J persists for approximately 4 weeks in moist soils, thus protecting against newly emerging leatherjackets. There is no known resistance of leatherjacks to Nemasys® J.

  • Effective biological control for leatherjackets
  • Persists in the soil for approximately 4-6 weeks
  • Natural product that is safe to users and lawns
  • Presents no risk of pest resistance
  • Can be used as part of an Integrated Pest Management (IPM) programme
  • Available in packs of 50 and 250 million nematodes

Steinernema feltiae is a natural soil dwelling nematode that infects susceptible leatherjackets that are feeding close to the soil surface by detecting cues such as carbon dioxide.

Once found, the nematodes then enter the leatherjackets through natural openings (mouth, spiracles, anus) or the skin. Once inside, the nematodes reproduce and release bacteria, causing the death of the larvae.

Larvae stop feeding within three days of infection and are killed 2-4 weeks later. Thousands of new nematodes are produced when resources become limited inside the cadaver and disperse in search of new leatherjackets.

  • Should be applied two weeks after a peak of crane flies to target young leatherjackets feeding close to the soil surface. Adult emergence normally occurs in August/ September (main peak) or April/May
  • Consider scarification in lawns with excessive layer of thatch
  • Cut the grass short before treatment
  • Soil should be between 10oC and 30oC during application and for at least two weeks after
  • Avoid application in direct sunlight; make applications in the evenings or in dull conditions
  • Ensure soil is moist prior to application and for at least two weeks after
  • Water the treated area thoroughly and immediately after application with no less than 3 litres per m2
  • The use of a wetting agent helps the penetration of nematodes into the soil
  • Two applications 2-4 weeks apart, would help achieve higher levels of control
