General information

When to use Sportnem-T

Use Sportnem-T for biological control of larvae of Tipulidae (crane flies), Noctuidae (owlet moths), Gryllotalpa (mole crickets) and various other species.

How Sportnem-T works

After application, the nematodes actively search for their prey and penetrate them. The nematodes feed on the contents of the prey, excreting specific bacteria from their digestive tracts as they do so. These bacteria convert host tissue into products that the nematodes can easily ingest. The larvae die within a few  days. Once the insect larva has been entirely eaten, the nematodes crawl out again to prey on other larvae.

How to use Sportnem-T


Preparation of the solution
  1. Half an hour before preparing the product, remove the pack from the refrigerator and let it come up to room temperature (20°C)
  2. Break the contents of the sachet (250 million Steinernema carpocapsae) into smaller pieces. Use the entire pack and place the smaller pieces in a bucket containing five litres of water (at 15 to 20°C)
  3. Leave the bucket with the solution to stand for five minutes
  4. Then stir the solution until all the lumps have disappeared before transferring it to the spray tank
  5. Use the spray solution straight away
Application and dosage
  1. Remove all gauze openings of less than 0.3 mm (50 mesh) in order to prevent blockages.
  2. You can use a watering can, backpack spray unit, motorized spraying system, or sprinkler system.
  3. Use as little pressure as possible (max. 20 bar)
  4. Use the contents immediately after preparation.
  5. Apply the solution homogenously over the area to be treated.
  6. Apply the solution late in the evening or early in the morning.

IMPORTANT: Spray the lawn before and after the application of the product with 2-5 liters per m2 and keep the ground moist for a period of two weeks after application.

Best working conditions

  • The moisture content of the soil must be high
  • Soil temperature between 14 and 33°C/57.2 and 91.4°F
  • Nematodes are susceptible to ultraviolet light (UV): do not use them in direct sunlight
  • Leaf applications should only be carried out in the evening to minimize the influence of UV light and to maximize moisture availability for the nematodes
