Encarsia for Whitefly
Whitefly is a major pest that can destroy plants in greenhouses and conservatories as both the adults and larvae attack the plant. Control Whitefly by introducing Encarsia AS SOON as whitefly appear and the temp is 10c.
Encarsia are introduced to the greenhouse on small ,white cards, which are simply hung on the lower leaves of the plants. The Encarsia seeks out whitefly scale and deposits an egg inside it. As the beneficial Encarsia develops INSIDE the whitefly scale, the whitefly is destroyed and turns black, before a new Encarsia emerges ready to repeat the cycle. It is safe for you, children, pets and wildlife. For smaller greenhouses with a light infestation use 2 introductions, but for larger greenhouses or heavier infestations use 4 or 8 introductions. If the infestation is really heavy i.e. the plants are covered in sticky deposits, spray with SB Invigorator natural spray (see natural sprays for more details) 1st and THEN INTRODUCE ENCARSIA - order our emergency pack consisting of SB Invigorator Concentrate sent 1st followed by 4 introductions of Encarsia starting 7 days later.
