Greenhouse whitefly (Trialeurodes vaporariorum); Tobacco whitefly (Bemisia tabaci).
How it works
|Pack size||3,000; 7,500; 15,000 pupae.|
|Presentation||Cardboard strips with 5 cards each, wrapped in plastic, in a cardboard box, each card holds 60 (30 for 7,500 product) parasitized whitefly pupae.|
Directions for use
- Open package carefully inside the greenhouse
- Bend and tear off the strips opposite to the mounting hole
- Make sure not to touch the pupae during handling
- Suspend the cards in the crop, if possible approximately 75 cm under the plant head
- Avoid to hang cards at places exposed to direct sunlight
The dosage of En-Strip depends on climate, crop and whitefly density and should always be adjusted to the particular situation. Start introduction preventively soon after planting of the crop. Introduction rates typically range from 1-10 per m2/release. Releases should be repeated until control is achieved. At increasing temperatures it may be better to switch to the use of Enermix or Ercal. Consult a Koppert advisor or a recognized distributor of Koppert products for advice on the best strategy for your situation.
The parasitic wasp is most effective at temperatures between 20°C and 25°C (68 and 77°F). At a 24 hours average temperature below 17°C/63°F the control of whiteflies may be insufficient.
En-Strip is best to be used in combination with generalist predatory mites (Amblyseius andersoni, Amblyseius swirskii, Neoseiulus cucumeris or Amblydromalus limonicus) or, in tomato, with predatory mirid bugs (Macrolophus pygmaeus or Nesidiocoris tenuis).
