You can still get rotenone dust?! I’m jealous! It’s the only thing that has worked for the last few years and they pulled it off the market. B/c there used to be so many big farms around here, most things are immune to sevin. :(
We’ve replaced ‘Sevin’ with ‘Eight’ spray or liquid concentrate. Many customers are mad that we can’t get ‘Sevin’ any longer, too.
I’ve worked very hard to develop a balanced Eco-System here on my little farm. I have very little problems with bugs because I have lots of birds, bats, toads, salamanders, snakes and good bugs that eat the bad bugs.
I know that’s not always the case in some parts of the nation! You can do all you can ‘organically’ and STILL have problems. :(
