Nemasys M

Biological

Nemasys® M contains the beneficial nematode, Steinernema feltiae and is effective against the larval stages of sciarid flies (Lycoriella spp.) that infect mushrooms (Agaricus bisporous).

Benefits

Advantages of using Nemasys® M:

  • Nemasys® M can be used in organic systems or as part of an IPM programme
  • Safe to users and the environment
  • No pest resistance problems
  • Simply applied as a drench to the casing surface

Why Nemasys® M?

Nemasys® M contains millions of beneficial nematodes of the Steinernema feltiae species and is effective on the larvae of sciarid flies (Lycoriella species) which infect mushrooms (Agaricus bisporus).

Beneficial nematodes are naturally-occurring microscopic worm-like organisms. Applied as a drench, they provide an effective, rapid and safe solution to control larvae of the sciarid fly.

Application advice
Nemasys M should be applied to the mushroom casing as a drench
To ensure activity over the whole cropping cycle (first and subsequent generations of flies) two applications should be made as detailed on the label
Do not exceed 300 psi/20 bar/2000 kPa pump pressure
Nozzle aperture should be greater than 0.5 mm
Suitable nozzles should produce a course spray at the intended application pressure
Make up the stock solution and mix thoroughly to ensure that the nematodes are well dispersed.
PrecautionsUpon receipt, use immediately or store in a refrigerator at 5°C
Do not use product if past expiry date or incorrectly stored (do not freeze)
Use entire packet at one time, do not store diluted product

How do Nematodes work?

• Nemasys® M should be used to treat larvae of the sciarid fly.

• After application the nematodes attack the larvae by entering natural body openings or by penetrating the pest cuticle directly.

• Once inside, they release bacteria that stop the larvae from feeding and which kill the larvae within a few days.

• The nematodes reproduce inside the dead larvae and release a new generation of nematodes, which disperse to hunt down further larvae.

• When nematodes can no longer find a host pest, they will die back to their original numbers. The more larvae there are, the better the nematodes perform.
