hi guys, Did you ever think about "diatamatious earth"? The Diatoms are little critters that have some wickedly sharp little shells that lacerate the bodies of the organisms that are infecting your garden. And through the little holes in there bodies (and some I guess swallow it--and cut up there guts) they loose moisture and shrivel up and die. the diatoms are often used to control weevils in stored grains and things (you can eat them along with the grain). I WOULD be careful though. they are made mainly of calcium, and if you suck them into your lungs, they might be there for a while.
I'm going to look it up on google, but if you go that way, make sure to wear a dust mask and keep it out of your lungs.
also, I seem to remember some recommendations about Murray's oil soap? Or maybe just some simple lye soap without any perfumes and coloring and crap like that?
just a couple thoughts, the coffee hasn't kicked in yet this morning. john
