The effects of "Gasol" grain preservative dosages on the growth of Fusarium graminearum and the quantity of the toxin zearalenone.

In earlier experiments regarding the effects of preservative "Gasol" (containing various acids and additional compounds and intended for whole grain preservations) in recommended dosages, prevents the growth of Fusarium graminearum and reduces the amount of zearalenone when added to milled grain. It was proved in the tests carried out that the smaller dosages of "Gasol" were sufficient for the prevention of growth of the fungus and reduction in quantity of zearalenone. The degree to which the toxin was destroyed depended on the dosage of the preservation. A dosage twice as strong as that recommended in the instructions for practice destroyed all the toxin formed in the grain. A very small dosage of "Gasol" (1/8 of recommended dosage) prevented the growth of the fungus and only slightly reduced the amount of toxin only at the beginning of the test. Later, the growth of the fungus was more vigorous and significantly more toxin was present in the treated grain than in the grain which had never been treated with the preservatives, it has been proved that the preservative
