Phenylmercuric acetate is an organomercury compound. This compound was formerly used as a preservative in paints,[1] and as a disinfectant.[2] When applied to the leaves of plants, it is an antitranspirant.[3]

Applications
Phenylmercuric acetate (PMA) has been used against antifungal activity in agriculture and in leather processing and has known to work well. PMA has also been used as an additive in eye-drops and paint in order to preserve them, as a disinfectant, and as a catalyst in polyurethane systems.[4][5] In the 1950s-1970s, PMA was used as a catalyst in the 3M Tartan brand polyurethane flexible floors that were commonly in school gymnasiums.[5] School officials worried that mercury vapor was being released into air above the surface of these floors. They had to be carefully removed since mercury is such a toxic heavy metal.
Findings
The study on PMA as an anti-fungal is the most studied topic for this compound. It has been found that plants treated with PMA transpired more due to the retarded stomatal closure in the plants. Day-time reductions in transpiration by PMA greatly exceed night-time increases in water loss. PMA stunts stomatal closures as well as openings.[6] Research has found that PMA may plausibly decrease the absorbency of guard cell membranes to solutes, thereby retarding all stomatal movements that are osmotically prompted.[6]
Hazards
PMA can cause Contact Urticaria Syndrome (CUS). Contact urticaria refers to a wheal-and-flare response occurring on the application of chemicals to intact skin. A wheal-and-flare response is a skin eruption that may follow injury or injection of an antigen. It is characterized by swelling and redness caused by a release of histamine. The reaction usually occurs in three stages, beginning with the appearance of an erythematous area at the site of injury, followed by development of a flare surrounding the site; finally a wheal forms at the site as fluid leaks under the skin from surrounding capillaries.[7] CUS has been categorized as an immediate hypersensitivity reaction with IgE (a type of anti-body) playing a crucial role in its pathogenesis.[8] Investigations dealing with CUS seem to suggest that a percentage of urticarias encompass a contact mechanism.[8]
