What is ENTONEM?

This product contains entomopathogenic nematodes (Steinernema feltiae) that can be used for the biological control of fungus gnats, thrips pupae, beetle larvae and young stages of the oak processionary.

How does ENTONEM work?

ENTONEM can be applied in two ways. First, you can irrigate the soil with the nematode mix. This method is effective against soil-dwelling organisms, such as fungus gnats, thrips pupae and beetle larvae. Secondly, you can sprinkle the nematode mix onto the crop. This method is effective against thrips larvae that reside on the leaves. In April, ENTONEM can also be used for the biological control of young oak processionary. This is effective as long as the caterpillars have not yet developed stinging bristles. The nematodes are sensitive to dehydration. The soil must be kept moist at all times. The leaf-methode is most effective when it is applied in the dark under moist conditions, since the nematodes are also sensitive to UV light.

After the nematodes have been distributed over the soil, they start to look for host larvae, which they will enter through openings in the body. They transfer bacteria which infect and eventually kill the beetle larvae. While the nematodes are very effective against larval stages, they do not have an effect on adult beetles or fungus gnats. Both before and after the distribution of the nematodes, the soil needs to be moist. The nematodes require a moisty environment to be able to move through the soil.

How to combine ENTONEM?

For the control of fungus gnats, ENTONEM is great in combination with HORIVER yellow sticky traps. The sticky traps can not only be used for monitoring, but can also catch a part of the small flies. This way you can catch the adult fungus gnats aboveground, while the nematodes take care of the larvae underground.

For the use of ENTONEM against beetle larvae, you need to keep an eye on the soil temperature. Starting from 8°C ENTONEM is the best choice. As soon as the temperature reaches 14°C and higher, LARVANEM is more effective.

User manual

  • Add the contents of the package in a bucket with 5L water (15-20°C).
  • Stir thoroughly and let it settle for 30 seconds. Stir again.
  • Dilute: add 0,5L of the nematode mixture to 9,5L water.
  • Make sure to stir properly during the whole process.
  • Diluting the whole package results in 100L of nematode mixture.
  • Distribute the nematode mixture over 50-100m2.
  • Use the whole package in once, because the distribution of nematodes is not homogenous.
