Evaluation of Fusarium mycotoxins and fungicide residues in barley grain produced in Uruguay
This work aims to survey the current barley grain situation in terms of the concentration level of Fusarium mycotoxins and fungicides used to control Ramularia Leaf Spot and Fusarium Head Blight in barley grain. For this purpose, a total of 89 barley grain samples from different commercial pads in U...
