This paper summarizes the physical, chemical, environmental and toxicological properties of the fungicide azaconazole, a chemical used in wood protection. It is active against several types of fungi, including basidiomycetes and ascomycetes, and fungi imperfecti.
Azaconazole undergoes photodegradation in water (half-life ~one week), but is not expected to undergo hydrolysis. It is moderately to strongly absorbed by soil depending on organic content, acidity and temperature, and has a low leaching potential. Azaconazole undergoes biotransformation slowly (soil aerobic half-life of 355 days), and has a low potential to bioaccumulate. According to toxicity scales used in this report, technical grade azaconazole is moderately to very toxic to experimental animals, depending on species tested and route of administration. Occupational exposure studies have not been done. However, related studies indicate that azaconazole levels in air should not pose health risks for persons in buildings containing azaconazole-treated wood. No significant dietary exposure is anticipated as a result of its use as an antisapstain.
