Fusarium genus is a filamentous ascomycete fungi with the ability to produce toxins. Sampling was carried out between 2015-2016 in three tea courses from Mazandaran and Gilan provinces. At intervals of 3, 7 and 15 days, the plates were examined and the colonies grown in each plate were identified and their macroscopic characteristics were recorded. Finally, 150 colonies were selected. Samples cultured in a plate were cultured in liquid medium sB + ME and sB + yE. The environments were examined for successive days and slides were prepared and stained with lacto phenol. This is to ensure the inactivation of fungi exposed to plasma or the removal of spores from the sample surface. There is a significant relationship between the DON produced in the potato medium containing yeast extract and DON contained in the sample taken from the same medium that was exposed to plasma jet for 60 seconds This feature was statistically significant in comparison between changes in the toxicity of T2 and toxin after 60 seconds of treatment with jet plasma and T2 reducibility severity to DON. Plasma treatment results showed a significant reduction in time-dependent toxin concentrations. These results indicate that the plasma system has a high potential not only to destroy mycotoxins, but also toxins produced from fungi, which can be greatly reduced and can be used effectively in the food industry.
