What else can I use to treat whitefly instead of pyrethrum
I've found pyrethrum ok for most of the plants, but it discolours the impatiens and fuchsias, leaving white streaks. I prefer organic, or not too toxic, so is there an alternative?

Hi Ruth,
Yates Nature's Way Vegie & Herb Spray Concentrate is effective on white fly. It is biodegradable and non-residual. It is best to apply it in the cooler part of the day ie late afternoon or early evening.
