Bioactive Metabolites and Potential Mycotoxins Produced by. << It is most common in Western Canada in wheat, barley and corn, but can also occur in oats, rye, canary seed and forage grasses. Fusarium head blight (FHB) of small grain cereals caused by Fusarium graminearum and other Fusarium species is an economically important plant disease worldwide. 2012 Nov 6;4(11):1157-80. doi: 10.3390/toxins4111157. Fusarium mycotoxin contamination of both foods and feeds is an inevitable phenomenon worldwide. Fusarium head blight (FHB) is a serious fungal disease of cereal crops that affects kernel development. Gibberella zeae, also known by the name of its anamorph Fusarium graminearum, is a fungal plant pathogen which causes fusarium head blight, a devastating disease on wheat and barley. ��]���S�O��}q܅:�$�qi�#�� (�̶O�:�����f��T�Cl��3Їv�J������P��2�Î;�y��~�� f�Lԓ]��Rr8���N3�Z,[�eA��ܴ-~��t�K+�G�Ck����:��4�o*G~�kO��l���l6H�JT����^�ms�IK� "�5�H�=�6紨c�dZ3��'�m���2z�;�Z�xw��o��YFvs�c;�%똂��ϧ�*��P=�=ܚ4�R?� T=[���zW�.��f"z��4��@�ͱL��uk�P�àn���,6�t\JIa6�Z܈*�x��0��G{8�n��f������rh��������#���=�1�M�pG����㎕�icӾ�s¢(�wD,����v���u�%H�iC' :�2z�j�T\9�*w�@��"f��ד�� Mycotoxin analysis showed F. graminearum (= lineage 7) isolates produce either nivalenol (NIV) or deoxnivalenol (DON).
