Efficacy of Muscodor albus-produced volatiles in preventing germination and growth of mycotoxin-producing Aspergillus, Penicillium and Fusarium species in vitro. Freshly-sown conidia on potato dextrose agar were exposed to volatiles for 24 h at 20 °C in sealed jars and then incubated for six days before determining the proportion of conidia killed or suppressed (dead or non-germinated conidia/total No. of conidia). Analysis of variance was conducted on angular transformed and non-transformed data. Transformation did not improve means separation, and therefore, the non-transformed proportion of conidia killed or suppressed from germinating is reported below.
