copper soap

I just picked up and used some copper octanoate spray (copper soap). My understanding is that while it is considered organic, there is concern about build-up in the soil. So, I'm wondering what is the consequence of too much build-up in the soil? I'm thinking that it would destroy beneficial fungi or maybe too much copper would be absorbed into the vegetables. Am I on track?

I had to get a little more aggressive than milk, baking soda, or neem oil. It's been too wet this season.

hello orgoveg,

Yes, Copper Soap is a fungicide so it could potentially harm any beneficial fungi that lives in your soil. you could try covering the soil with a plastic bag or something while you spray the copper soap then remove it after the application. you could also try potassium bicarbonate which is much more effective then baking soda(sodium Bicarbonate) and is available as Green Cure, certified by the USDA for organic production. hope that helps. Cheers!
