Best Copper spray for California

Tried to buy a Copper Spray (southern Ag Liquid copper) online but it doesn’t ship to CA. It contains 8% copper. Most that I find here contain 1.8% copper.

Anyone know of anything stronger that can be purchased in CA.? Having issues with both Peach Leaf Curl and Black spot/Greasy spot on citrus. My Liquid copper isn’t doing the trick.


I ordered this from Amazon. It was shipped to me in California.


Thanks. I tried buying through Amazon Prime and said they couldn’t ship to my address. Tried through regular Amazon and apparently it is coming.
