[2] Antimycin A is the active ingredient in Fintrol, a chemical piscicide (fish poison) used in fisheries management.

[3] Fintrol ® is the only currently registered product containing antimycin A and is classified as a restricted use pesticide because of its aquatic toxicity and requirement for highly specialized training in order to use it.

In 1993, several toxicology studies were submitted to the United States Environmental Protection Agency yielding its toxicity.

[citation needed] In aquaculture, antimycin A is used as an agent to enhance catfish production via selective killing small and more sensitive species.

[citation needed] It has also been found to inhibit the cyclic electron flow within photosynthetic systems along the proposed ferredoxin quinone reductase pathway.

[citation needed] Fungus-growing attine ants have been shown to use antimycins - produced by symbiotic Streptomyces bacteria - in their fungiculture, to inhibit non-cultivar (i.e. pathogenic) fungi.

From there, the EPA describes methods to determine a reference dose (RfD), the upper limit of the substance that can be consumed daily for the rest of one's life without any observable consequences.

Animal toxicology studies suggest that exposure to less than 40 grams of antimycin A can result in serious adverse health effects to the individual.

[13] Treatment is focused on relieving symptoms and monitoring for respiratory distress, pulmonary edema, seizures, and shock.

After inhalation the patient should be moved to fresh air and monitored for bronchospasm, difficulty breathing, and respiratory distress.
