Effect of Neem oil on beneficial bacteria in Veggie garden

March 24, 2011

Another gardener on Garden Web had suggested a book to me titled "Teaming With Microbes". I'm enjoying the book and it's enlightened me to quite a few things I had no idea of. Anyway, the entire premise is the microorganism start the work of supplying nutrients to plants if you have healthy soil.

Now my question, I've used neem oil spray concentrate the last 2 years liberally and as my only type of insect and disease control. But now I'm wondering if using neem destroys my good bacteria and fungus and suppresses what I'm trying to encourage?

I made the switch to learning and practicing organic 2 summers ago. My results have just been ok not great but I know I still have tons to learn.

Thanks in advance.
