| Abstract | ||||
| Oilseed crops including maize, soybean, peanuts and cottonseeds were treated with butylated hydroxy anisole, butylated hydroxy toluene, propyl gallate, propionic acid and dimethyl sulfoxide to control toxigenic fungi. The same chemicals were added to liquid medium and mycelial growth and aflatoxin production by Aspergillus flavus was determined. Propionic acid was the most effective in reducing the level of fungi in seeds. At 0.2 ul/ml, no fungi occurred on cottonseeds, while with the other oilseeds the percentage of seeds with fungal growth ranged from 10-50%. In liquid medium, however, propionic acid reduced growth of A. flavus but aflatoxin production was stimulated. The most effective chemical in reducing growth and aflatoxin production was butylated hydroxy anisole. At 0.6 ug/ml, mycelial growth was reduced to 90% and no aflatoxin was detected. The use of antioidants had potential as means of control agents against toxigenic fungi in countries that lack adequate drying and storage conditions. | ||||
