Inhibitory effects of acetophenone or phenylethyl alcohol as fumigant to protect soybean seeds against two aflatoxin-producing fungi.

ABSTRACT: The antifungal activity of acetophenone and phenylethyl alcohol prevents seed contamination by Aspergillus flavus TISTR 3041 and A. parasiticus TISTR 3276. Their effects on seed germination were investigated. In vitro results showed that 100 µL L^-1 acetophenone completely inhibited (by 100%) growth, conidial germination, and sporulation of the two aflatoxin-producing fungi, while phenylethyl alcohol showed only weak inhibitory activity even at 1000 µL L^-1. Exposure to acetophenone at 100 µL L^-1 for 6 h could completely kill (100% death) both fungal strains, while phenylethyl alcohol showed much lower efficacy (53.12%). In vivo results revealed that fumigation with 100 µL L^-1 acetophenone for 24 h completely controlled (100%) A. f
