	Growth inhibition**	Viability***	Growth inhibition	Viability
Aspergillus niger	6.8	+	100	-
Alternaria alternata	40.7	+	100	-

* The concentrations was 0.5 mL/L air space.

** Growth inhibition after 6 days was calculated as percentage inhibition compared with that of a control grown under the same conditions in the absence of the chemical compound.

*** Viability of the tested fungi after 6 days of exposure to the chemical compound.
