Penicillium digitatum bench test Conducted by CA EPA.

Concentrations (mg/L) of sanitizer that inhibit 50% (EC50) or 99% (EC99) of germination of conidia of P. digitatum exposed to them for 10 min at 23 C. Germination was determined after incubation on potato dextrose agar for 18H. Concentrations and 95% confidence intervals (Cl) were estimated using Finney’s Probit analysis.
