General information

When to use Capsanem?

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

How does Capsanem work?

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.

Application Capsanem

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
  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 Capsanem

  • The soil must have a high moisture content
  • Soil temperature between 14°C/57.2°F and 33°C/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


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 expiration date
  • Storage temperature: 2-6 °C/35-42.8°F
  • Store in a dark place
