It just says there's no "research" to back it up. (see below)
Well all I can say is (again) I've had VERY high levels
of JB over the last 4-5 years despite very dry summers
(something that hinders JB eggs from hatching) and
I can definately see a big reduction since putting down
the Milky Spore last year and a major deduction in moles
as well.
I'm looking forward to seeing what its like next year.
MSU info...
"Milky spore products: A product available in
Michigan contains a bacterial spore that is
supposedly effective in reducing Japanese beetle
populations. There has been little evidence
presented in the scientific literature over the past
two decades that indicates any milky spore containing
products work. More research is needed
to demonstrate the efficacy of milky spore products
before we can recommend them for grub control."
How are your Japanese Beetles levels this year?
Ladies, Ladies, the key words here are " before we can recommend them for grub control". Those of you who are Master Gardeners know that Michigan State needs to be 110% sure before they will put their stamp of approval on it.
Vickie if it works for you, then that is good nuff for me. Just sticking my 2 cents in.......

I agree Deann
Never heard of this one before:
Japanese beetle buster...
Throw a handful of larkspur or delphinium leaves into a blender, add the blend to 1 gallon of water and spray the mixture onto plants being attacked by Japanese beetles. The deadly alkaloids (deliosine and delsoline) in the leaves will zap the beetles.
They were horrible last year and I haven't had to many this year at all...knock on wood ^_^....I've only heard of good results with milky spore...
