What sort of experiences have you (anyone) had with using 501 in a
greenhouse? I think that Grotzke advised that it is too strong for
use in a greenhouse. (?) For this reason, I have held off using it.
First outbreak of aphids makes me think of using it. I think heinz
mentioned a residual and a generalized effect that henceforth makes
the house uncomfortable for seedlings.
But, what is you life experience?
Thanks
