The Organic Master Gardeners praise the Espoma product. I would take it to the bank ( trust it) However, the 'Plant tone, etc; ....don't know. See the Dirt Doctor's web site>Library>E>Espoma. I think this product is for pest control, mainly Grasshoppers. Colin' Clay may be the best deterant. In baby Grasshoppers, No-Lo, is for the Baby weed hoppers. Redman's clay, also, for grown Grass Hoppers.
