i posted on that subject when they first changed it. i was worried it wouldnt be as good. ive used it since then and dont have any problems, it still kills jap beetles and i use neem and soap for the aphids. i mainly use it on my peach trees and it works about as well as the carbaryl formulation and it has a lower phi.Think sevin is no longer carbaryl. If you can find real sevin dust with carbaryl, that would work, I usually spray liquid sevin(carbaryl) on plants. I don't know anything about this new sevin chemical or how effective it is.
I have heard and read some people swear by dawn dish soap as an effective alternative but never tried it.
