The basic requirement
Any agricultural or vegetable seed, or mixture, for seeding purposes that has been treated shall be labeled in type no smaller than 8 point to indicate that the seed has been treated and to show the name of any substance or a description of any process used in the treatment.
The form it takes
The rule gives the pattern: "Treated with ____" naming the substance or process, or "____ treated". Short, explicit, and not left to the labeler to phrase.
Which name to use
The commonly accepted coined, chemical or abbreviated chemical name. Coined names are free for general use and commonly recognized as naming a particular substance; the rule gives thiram and captan as examples, and calcium carbonate as a generic chemical name.
Biologicals name the organism or the brand
The label includes either the name of the genus and species or the brand name as identified on biological product labels. So a biological treatment is disclosed as specifically as a chemical one.
Where it may appear
On the tag bearing the analysis information, on a separate tag, or printed in a conspicuous manner on a side or top of the container. That flexibility matters for a small packet where the front panel is already full.
More statements if it is harmful
If the substance in the amount remaining with the seed is harmful to humans or other vertebrate animals, additional statements are required, and mercurials and similarly toxic substances have their own paragraph with stronger requirements.
Do not inherit a treatment claim
If you repackage treated seed, the disclosure is on your label and the substance name has to be right. That is information to get from the supplier in writing before packing, not afterwards.
