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.}}

Features

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

How Nemasys^® J works

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.

Application

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
