Spinosad & Bt with bees
I've sprayed my brassicas with both of these, thinking it was completely safe for the bees. I was sure I'd read that... somewhere.
Tonight, I stumbled upon some comment somewhere saying that Spinosad was, in fact, highly toxic to bees. A bit more reading and I'm fairly confident in my continued use as long as I do it in the evenings, when the bees are not out & about. It seems it's not such a threat to the bees once it has dried.
Now I'm reading on Bt and it's not looking quite so promising. There's a heck of a lot of conflicting info and I'm having trouble sorting it out.
They are the only two things I have ever used (other than a crazy, ignorant summer with Sevin, long, long ago...) -- and the only way it seems I can grow brassicas. I just tried Spinosad for the first time last year and this year is my first trying Bt.
What are your thoughts on both of these, especially in regards to bees? I think I'm most concerned with Bt at this point.
