The active ingredient in Quintox is Cholecalciferol which is vitamin
D3. OMRI lists Cholecalciferol in it's "allowed substance" materials

just checked again and it is still listed. The product "Quintox" is not
a listed product per se.


Just a general caution to those certified organic:

Always check with your own certifier before using any specific product. Sometimes the active ingredient is indeed OMRI listed, but "inert" ingredients are in the product that are prohibited: in which case the product as a whole will be prohibited. (Also, of course, something may be OMRI listed as "regulated", but the specific operation may not be meeting the criteria to use it.)

Individual certifiers also may refuse to approve a product if they can't get a complete ingredients list. In some cases the product might actually contain only permissible materials; but if the manufacturer won't tell the specific certifier what's in it, the certifier has no way to tell.

Some permissible products are not OMRI listed; I gather that it's expensive to get on the OMRI list. If the certifying agency can verify that all the ingredients are permissible, the agency can allow use of a product not OMRI listed.

(For anybody who doesn't already know this: the word "inert" on a label -- whether a farm product or a medication -- does not mean "this ingredient is known to have no effects whatsoever". In the specific technical sense in which it's used on labels, it means only "this ingredient has no known effect on the pest or disease the product is labeled to work against". The "inert" ingredient may however have effects on other aspects of the system.)
