The susceptibility of turbot aquareovirus to five chemical agents was
examined. Treatment with 5 mg of malachite green per liter or 500 mg o
f iodine per liter resulted in a 90% reduction in virus titer within 1
h. Complete inactivation within 5 min was obtained with 2% formalin,
42.5% isopropanol, or 15 mg of free available chlorine per liter. Lowe
r concentrations of chlorine were ineffective.
