im considering trying them on putting greens and would like to know if anyone has used them and how they worked out. bacillus popillae-dutky to be exact. thanks in advance.

Try contacting St. Gabriel Laboratories in Louisiana to see if they can give you more information on these. www.milkyspore.com or 800-801-0061

Being organic for many years, I haven't had to use Milky Spore myself but see it as a viable product in cases where it is needed.
Hope that helps.

Sorry. St. Gabriel is based in Virginia, not Louisiana.
