This week on the Sunday gardening programme on Radio Kent either Andy Garland or Steve Bradley recommended a product called SB Plant Invigorator which advertises that it will solve a multitude of problems. Since I always have problems with red spider mite on my greenhouse cucumbers and even regular misting doesn't seem to get rid of them I thought I would give the product a go. Has anyone else tried it, and does it work?

The Safety Data sheet http://www.sbproducts.co.uk/SafetyData.aspx
seems ok, but not sure that the stated ingredients will kill anything. Sulphur and Urea are not really insecticides as such, unless there is something else in it.
