Growing Success Fruit & Veg Bug Killer 800ml Spray

I have previously used Growing Success Organic Fruit & Veg Bug Killer made by the Wessex Horticulture Group: it used fatty acids (sometimes called soaps) to kill bugs.When a fatty-acid soap touches the outer body, or cuticle, of an insect or plant tissue it will eventually lead to dehydration and death of the pest. These soaps rapidly biodegrade in soil (Olkowski 1991). Therefore, it kills by contact alone. If you have a pest problem, and you can see the pest (aphids or scale insects, say) you can selectively spray the pest, knowing that by not spraying beneficial insects (ladybirds, hover flies, lacewings etc) you cannot harm them. The fatty acid is not absorbed into the plant, or conveyed to the nectar or pollen, in any way.However, William Sinclair Horticulture have taken over the brand name and CHANGED the formulation. It is now called Growing Success Organic Fruit & Veg Bug Killer Ultra (spot the difference?) and contains pyrethrins. These are naturally occurring organic compounds which are absorbed by the plants and kill bugs SYSTEMICALLY. It is then impossible to stop beneficial bees from collecting nectar or pollen from a flowering plant, which had been previously sprayed with this new formulation, and being killed.The new formulation is therefore much more difficult to apply and to be certain that beneficial insects will not be inadvertently harmed.That is a crying shame. The addition of "Ultra" to the name of the new formulation hardly shows up in searches, so it is easy to be misled (I was). The old formulation is no longer available (shame). Also, my bottle LEAKED in the post, causing a big mess, but I was refunded (thanks).
