CAPSANEM

 

Unit of packaging
Steinernema carpocapsae (entomopathogenic nematode)
Standard CAPSANEM pack size: bag in a box
Contains: 50 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)

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 (= 1000 litres/hectare)
• a wetting agent improves efficiency
• make sure plants are uniformly sprayed with the CAPSANEM spray solution, but avoid wastage through runoff

 

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.
