Encarsia

Whitefly (496)

Whitefly - unsuccessful (496)

Infestation of whitefly on various cabbage plants. A treatment of 3 sprayings on 3 successive days had no effect on the whitefly. (496)

Whitefly on various cabbage plants (savoy cabbage, cauliflower + brussels sprouts, approx. 10 plants each). Preventive watering with Encar. 6 – at the time of planting was more or less ineffective. Plants were also given garden lime during planting. Spraying of the leaf upper and lower sides with Encar approx. 2 days after noticing the infestation led in one week to only a slight reduction. However, the plants showed only a few yellow areas and leaf deformities (= improved resistance?). Then watering with a homemade solution of nettles -> infestation almost gone within 2 weeks. Weather warm and dry (mid-June 2010, Stuttgart, Germany) (496)
