NemaTrident® S

For biological control of a range of insect pests in mushroom cultivation

NemaTrident® S is a naturally occurring insect parasitic nematode (Steinernema feltiae) for control of the following common pests that attack mushrooms:

  • Mushroom Sciarids (Lycoriella spp)
  • Fungus Gnats (Lycoriella spp., Bradysia spp.)

Controlling these insect pests with synthetic pesticides is damaging to the environment, faces increasing regulatory pressure and is becoming less effective as the insect pests increasing their resistance.

There is another way to prevent insect damage that is environmentally-friendly, cost effective and simple to use. This new pest control product provides a 70-98% kill rate of these pest larvae down to 8°C – making it the most effective and flexible product in the market.

The Bionema Approach

At Bionema we work with nature by identifying and developing biopesticide products that target specific insect pests.

Our NemaTrident® Tri-Component System nematode products incorporate a range of highly virulent insect-parasitic nematodes within the Heterorhabditis and Steinernema genera. These nematodes attack and destroy the larvae of the insect pest thus preventing future pests from developing. They are safe, non-toxic to users and consumers, decompose rapidly and can be targeted at specific pests to avoid harming beneficial insects.

After application, nematodes actively search for insect larvae in soil or growing media (1). The nematodes penetrate the larvae and release a deadly bacterium (2). The infected larvae die and a new generation of nematodes reproduce inside them (3). The new nematodes emerge from the dead larvae (4) they then search and infect further larvae (1).

Bionema’s Tri-Component system is up to 20-30% more effective than other nematode products in the market

In order to optimise the effectiveness of these nematodes we have incorporated them into the Bionema Tri-Component System which consists of:

  1. The NemaTrident® specially developed, highly virulent strain of beneficial nematodes.
  2. The Nemaspreader® specialist soluble compound that helps Bionema’s beneficial nematodes to spread and thrive.
  3. Specialist training and advice for our customers on how to optimise the effectiveness of the nematodes.

By using Bionema’s unique Tri-Component System, customers benefit from powerful pest control without disrupting beneficial insects or causing any concern about development of insect resistance, residues, or worker safety.
