Steinernema feltiae
ENTONEM

Unit of packaging
Steinernema feltiae (entomopathogenic nematode)
Standard ENTONEM pack size: bag in a box
Contains: 50 million larvae (third stage) in inert carrier material
Large ENTONEM pack size: 2 bags in a box
Contains: 2 x 250 million larvae (third stage) in inert carrier material

Target

  • Larvae of sciarid flies (Sciaridae) (soil application)
  • Larvae of thrips (leaf application)
  • Pupae of thrips (soil application)
  • Larvae of black vine weevil (soil application)

Preparation of spray solution

  • Put the contents of the pack into a bucket containing 5 litres of water (15-20°C)
  • Stir well and leave to soak for 20-30 seconds
  • Stir well once again and pour 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 depends on application method
  • 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 per m² mixed into a 0.125 litre spray solution (=1250 litres/hectare)
  • A wetting agent will improve efficacy
  • Spray the crop evenly with the ENTONEM solution
  • Repeat treatment weekly as long as necessary



Environmental conditions

  • The moisture content of the soil must be high
  • Soil temperature between 8 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


Storage and handling

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


Appearance Larvae (third stage): size 0.9 mm long
Other stages: develop inside host

Mode of action 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.

Visible effects
Affected insects turn yellow to light brown and become slimy or dehydrated. They are therefore often difficult to find.

Important!
The quantities of this product used should be adjusted to the mode of action of the product and the results that can be expected in the crop in which the product is applied. Your local Koppert consultant or recognised distributor will be able to advise you on the correct usage.
Only use products that are permitted in your country and the crop concerned. Check local registration requirements.
