Re: cutworms, grubs, Japanese beetles, June bugs

Square Foot Gardening List - http://www.flinet.com/~gallus/sqft.html

I think it is not Bt on the soil that kills grubs, but another biological
agent, sold under the names Milky Spore, Doom, etc...

Bt on the lawn or garden can help take out lepidopterans (this is Btk
Bacillus thuringiensis kurstaki)....Bt san diego is good on beetles like CPB
(Colorado Potato Beetle) but I've not heard it recommended as a soil
drench....

Those spiky sandles will kill up to fifty percent of BWGs (Big White Grubs)
in yer lawn and garden, if you walk over it five or six times; then apply
yer nematodes, and finally the milky spore stuff for long term control, and
hey! You don't have to use the evil nerve toxin chemicals like Diazinon and
chlorpyrifos, which is nice...

Frank---he hardly ever lets his kids eat bugs, except under expert
supervision at the Montreal Insectarium....but thanks for that rose chafer
warning!
