Encarsia for controlling Whitefly - Whitefly have been a major pest in greenhouses and in large numbers they can devastate plants. Most commercial glasshouse crops are protected from whitefly by introducing Encarsia and you can use Encarsia in youe greenhouse / conservatory in exactly the same way.
Protect your plants by introducing a natural parasite of whitefly called Encarsia Formosa. They are most effective if they are introduced as soon as the first whitefly appear and the temperatures are above 10°C / 50°F. Encarsia are introduced into the greenhouse on small white cards which are simply hung on the infected plants.
