Whitefly Control

Whitefly is a major pest in amatuer & commercial greenhouses and in large numbers whitefly can devastate plants. Commercial growers turned to a biological predator called Encarsia in the 60's and 70's and now most glasshouse crops are protected from whitefly in this way. You too can use Encarsia in YOUR greenhouse / conservatory in exactly the same way as a commercial grower.

  1. Encarsia for Whitefly from

    Control whitefly in your greenhouse / conservatory by introducing Encarsia Formosa AS SOON as the 1st whitefly appear and the temp above 10°C / 50°F. Encarsia is a natural parasite of whitefly, which lays its own eggs inside the whitefly scale, so instead of a whitefly emerging another Encarsia is born. As Encarsia numbers build up the whitefly are controlled. Encarsia is safe to use on food crops i.e. use it on tomatoes in greenhouses. Each order for Encarsia consists of separate deliveries of 5 Encarsia cards at 7 day intervals - this allows the Encarsia numbers to build up naturally resulting in better control. Simply choose how many weeks you want the programme to last.

    N.B. If the infestation is heavy, increase the quantity to have more cards delivered in each delivery i.e. up the quantity to 2 and 10 cards will be delivered per delivery.
