OMRI and OCIA? It seems that there are acronyms everywhere.
Pesticides, herbicides, and fertilizers, which have OMRI or OCIA on the label are independently certified for use in organic gardening. If a product does not have OMRI or OCIA on the label that does not mean it cannot be used in organic gardening but it may mean that the company did not choose to have the product tested. If a product does have OMRI or OCIA on the label you know it has been certified by a third party for organic gardening and landscaping.
