It sounds like Bordeaux mixture. Read up on it, and read, read again.

Now you have me worried lol , is this a NO No ??, old Grrek Mate sez he uses this mix and works a treat for him ??.
Might have to try some on a small plant first see what the outcome is and then see from there on ??..

Yep, Bordeaux mix indeed.

It likely would be best to contact an agricultural agency, if you have one in your area.. There are places in the world where it is banned, or at least has a restricted use.

Thank you for that Mate and appreciate the feedback , will refrain from use till further research as they sell the Bluestone here as well as other ingredients ..
Know that powdery is a big issue here come the hotter wetter months and was looking for known aids in this arena..
