Stability of prepared disinfectants in prolong storage for their effect in deactivating Tobacco mosaic virus (TMV) infectivity. A). Comparative effectiveness of freshly prepared 10% Clorox® bleach solution (Fresh) and a similarly prepared solution in storage at room temperature (20–30°C) for 30 days. The positive control (TMV only) without treatment was used to assess the TMV infectivity in the inoculum. B). Comparative effectiveness of 2% Virkon S solutions from a freshly prepared (Fresh), those in storage for 10 days (10 days) and 30 days (30 days) after preparation at room temperature (20–30°C). A positive control (TMV only) was used to assess TMV infectivity in the inoculum.
