Abstract
The effects of clove oil and citral on the growth of Aspergillus flavus, A. niger, A. oryzae and Rhizopus, and potential use as fumigants for poultry feeds, were examined. Proliferation of all fungi tested was reduced when clove oil and citral were added to potato dextrose agar medium at 600 and 1500 mg/kg, respectively. Clove oil and citral were evaluated as fumigants at a dose of 5 ml/20 g of each feed sample, in sealed polyethylene bags for different exposure periods. After 24 h of exposure, 90% inhibition of fungal growth was observed with clove oil vs. 78% with citral. When the exposure time was increased to 72 h, both compounds inhibited fungal growth by 94%.
