Using fox urine to repel rabbits is not a pheromone. Plant or leaf coatings designed to protect against frost or to retard water loss through transpiration. These types of products are usually glycerol-based. Similar products are sometimes sold as cut-flower preservatives.

Antimicrobial products used solely in processed foods or feeds, in beverages, or in pharmaceuticals. On some federal labels certain restrictions or special directions may pertain only to a certain state or set of states. When these requirements are not federally mandated, but required by the state, EPA may allow such restrictions on the label. The statement should make it clear the restriction is due to a State law, not a Federal one. This Guidance Document requests states to submit some new information such as a more detailed explanation of the special local need and a statement of no unreasonable adverse effects for unregistered formulations.
