<i>Ammoides pusilla</i> Essential Oil: A Potent Inhibitor of the Growth of <i>Fusarium avenaceum</i> and Its Enniatin Production

Enniatins are mycotoxins produced by <i>Fusarium</i> species contaminating cereals and various agricultural commodities. The co-occurrence of these mycotoxins in large quantities with other mycotoxins such as trichothecenes and the possible synergies in toxicity could lead to serious foo...
