General information

When to use Capsanem
Use Capsanem for biological control of larvae of the families of Noctuidae, Pyralidae, Tipulidae (crane flies) and the great pine weevil (Hylobius abietis) and Capnodis tenebrionis. Larvae of various other Coleoptera (beetles) and Orthopthera (e.g. mole crickets).

How Capsanem 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.


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. With a watering- can, sprinkler system, backpack spray unit or vehicle-mounted spray unit

  2. To avoid blockage, all filters should be removed

  3. Use a maximum pressure of 12 bar on spraying boom or pistol

  4. The spray nozzle opening should be at least 0.5 mm (500 microns)

  5. Continuous mixing should take place to prevent nematodes sinking to the bottom of the spray tank

Soil application

  1. Dosage of 0.5 million nematodes/m²
  2. Amount of spray solution strongly depends on application, use at least 3000 litres/hectare to control Duponchelia
  3. Water the crop before and after application
  4. Distribute the spraying solution evenly over the soil surface
  5. Keep the soil moist for the first 2 weeks after application

Leaf application

  1. Use 0.25 million nematodes/m² diluted in 0.125 litre spray solution/m² (= 1,250 litres/hectare)
  2. A wetting agent improves the effect
  3. Make sure plants are uniformly sprayed with the Capsanem spray solution, but avoid wastage via  runoff

Orchard or fruit tree application

  1. Dosage 1.0 million nematodes/m²
  2. Use 5-10 litre per tree
  3. Do not apply on dry soil, nematodes should be applied after pre-irrigation or rain fall
  4. Keep the soil moist around  the tree for at least two weeks after application

Best working conditions for Capsanem

  • The moisture content of the soil must be high

  • Soil temperature between 14 and 33°C

  • 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 minimise the influence of UV light and to maximise moisture availability for the nematodes

Biological beneficials have a very short life expectancy and therefore need to be introduced into the crop as soon as possible after receipt. Failure to do so can have a negative impact on their quality. In case you do need to store Capsanem, please follow the instructions below. Koppert B.V. is not liable for any loss of quality if the product is stored longer and/or under different conditions than recommended.

Storage instructions:

  • Shelf life: see package for expiry date
  • Storage temperature: 2-6 °C
  • Store in a dark place

The information given below is merely indicative. Tailored advice requires detailed information on local factors, such as the crop itself, climate conditions and the level of infestation. To ensure a correct approach, please consult a Koppert specialist or a recognized distributor of Koppert products.

In case of application/irrigation per pot: 5,000 nematodes per litre of pot volume.
