Gazelle SG 500 g Insecticide, looked intersting, its on ebay cheaper. https://www.progreen.co.uk/gazelle-sg-s ... gKekvD_BwE
Gazelle SB is a highly effective, broad-spectrum, systemic insecticide. Ideal for use against a large variety of plant chewing and sucking pests. On label approval for use against aphids and whitefly with EAMUs for specific weevil species.
Hi Tina,
For those that might be curious: The primary compound in Gazelle SG 500 is acetamiprid, which is a chloropyridinyl neonicotinoid, much like imidacloprid.

It can stay looking interesting at that price!! £122!!
They're both acetamiprid but the concentrations and methods of delivery are different.
Bug clear ultra VW killer is 5% acetamiprid. 60ml is mixed with each litre and that treats 10 litres of compost. A whole bottle is only supposed to treat 80 litres of compost
The Gazelle is 20% acetamiprid and is mixed at 0.25g per litre but then sprayed onto foliage, not drenched (according to the label).
Obviously Gazelle is granular and BCU is a liquid but I do wonder whether some of the issues with BCU is that people don't apply enough to each pot for effective control. It says a whole bottle only treats 80 litres of compost. That is only 80 4.5" square BEF pots and only about 400 7cm square pots. It only makes 8 litres of solution so that means 100ml needs to be applied to each litre pot.
I used 2 bottles treating most of my greenhouse yesterday and need some more to finish the job! And I'm still not sure I used enough for some bigger pots!
The bottle of Bug Clear Ultra I bought makes 20 Litres of solution. That's not much for €20
I dab any visible bugs with meths first. I always stand the plants in the solution for an hour or more and them spray. So it takes time.
The question here is how often to replace the solution in the tray. Comments welcome.
I'm aware it doesn't kill the eggs so there is a risk factor.....
I'm still seeing some on the move after four days. Some dead on the table top also.
But it's the eggs I'm worried about....
Its £55 ish on ebay & the seller offered a discount at £47 for a large volume.
This seemed a more useful product as its not a soil drench but absorbed in the plant a bit more direct but I could be reading it wrong
Tina
varied collection of succulents and cacti but I especially like Euphorbia's, Ariocarpus and variegated agaves.

Having just spent £60 on 6 bottles of BCU then the Gazelle looks like a more economical option!
Has anyone read anything about how well cacti absorb foliar systemics through their cuticle? Most foliar sprays are designed to be sprayed on plants with leaves which have a much larger surface area to volume ratio and less waxy coverings.
Could root drenches (done at the recommended dosage) be more effective for cacti?

Big nurseries probably don't keep 'rescuing' plants from neglected collections and reintroducing pests every few months.
Good point, Phil.
Many of the plants I buy are so severely infested with mealy
bugs and other pests.
