CAPSANEM

Steinernema carpocapsae

Unit of packaging Steinernema carpocapsae (entomopathogenic nematode)
Standard CAPSANEM pack size: 2 bags in a box
Contains: 2 x 25 million larvae (third stage) in inert carrier material
Large CAPSANEM pack size: 2 bags in a box
Contains: 2 x 250 million larvae (third stage) in inert carrier material

Target

  • Larvae of soil and leaf-dwelling pests from the families of Noctuidae (noctuids)
  • Larvae of Pyralidae (e.g. Duponchelia fovealis)
  • Larvae of Tipulidae (crane flies)
  • Larvae of the great pine weevil (Hylobius abietis)
  • Also effective against the larvae of various pests belonging to the orders Coleoptera (beetles) and Orthopthera (e.g. mole crickets)
  • Larvae of Capnodis tenebrionis



Preparation of spray solution

  • Put the contents of the pack into a bucket containing 5 litres of water (15-20°C)
  • Stir well and allow to soak for 20-30 seconds
  • Stir well once again and poor the entire solution into the spray tank
  • Top up until the required amount of solution is in the tank
  • Spray immediately after preparation
  • Use the whole pack in one go, as the distribution of nematodes in the pack is not homogenous!

Application and dose

  • With a watering can, sprinkler system, backpack spray unit or vehicle-mounted spray unit
  • To avoid blockage, all filters should be removed
  • Use a maximum pressure of 12 bar on spraying boom or pistol
  • The spray nozzle opening should be at least 0.5 mm (500 microns)
  • Continuous mixing should take place to prevent nematodes sinking to the bottom of the spray tank

Soil application

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


Leaf application

  • Use 0.25 million nematodes/m² diluted in 0.1 litre spray solution/m² (= 1,000 litres/hectare)
  • A wetting agent improves efficiency
  • Make sure plants are uniformly sprayed with the CAPSANEM spray solution, but avoid wastage through runoff

Orchard or fruit tree application

  • Dosage 1.0 million nematodes/m2
  • Use 5-10 liter per tree
  • Don’t apply on dry soil, nematodes should be applied after pre-irrigation or rain fall
  • Keep the soil surrounding the tree moist for at least two weeks after application



Environmental conditions

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

Storage and handling

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



Appearance

Larvae (third stage): size 0.5-0.6 mm long
Other stages: develop inside host

Mode of action After application, the nematodes actively search for their prey and penetrate them. The nematodes then feed on the contents of the prey, excreting specific bacteria from their digestive tracts as they do so. These bacteria convert the host tissue into products that the nematodes can easily ingest. The larvae die within a few days.

Visible effects Affected insect larvae change colour and become slimy.
