Not sure if it's appropriate for your needs but I use DDAC as a biocide from Mistral. Very strong stuff. Diluted 50:1 kills anything I have sprayed with it!
Interesting as I have a similar problem, the garden table I made is covered in black mould spots on the top. It is treated wood and after sanding smooth I gave it two coats of boiled linseed oil. Without sanding it right back, is there anything I can use?
