Does anyone use chitosan to kill bacteria and wild yeast? I’ve been reading about it’s use as a biological control in conjunction with so2 to control Brett mostly, but pretty much all bacteria and wild yeast.

I haven't. What is the concentration used for biological control vs. for fining?

I’ve been using oenobrett for 4 years as a preventative. One of the growers I used to buy fruit from recommended Lysozyme at 10 brix to get ready for malo and then a chitosan after malo is done. I’ve been happy with the results.
If what I’ve read makes sense llalemand uses 2 grams per 26 gallons. More wine sells a 32 oz bottle of 1% chitosan for $20. That’s about 9 grams of chitosan. I think I’ll try it.
