The product CAPSANEM contains the nematode Steinernema carpocapsae that can be used for the biological control of caterpillars, leatherjackets and beetle larvae. The nematodes can be applied both aboveground and in the soil.

How does CAPSANEM work?

As soon as the nematodes have been released, they actively start to look for a host. They will enter their through openings in the body, transferring bacteria which infect and eventually kill the host. 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. The soil temperature has to be between 14 and 33 °C. When applying aboveground, it is recommended to release the product in the evening to prevent exposure to UV. By controlling the larvae and caterpillars, no new adults will develop, which strongly reduces pest numbers.

How to combine CAPSANEM?

Against moths, CAPSANEM is great in combination with DELTA TRAPS that contain a species-specific pheromones to attract moths. For use against beetle larvae LARVANEM is recommended.

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.
