A method for the detection of Fusarium graminearum (Gibberella zeae) comprising the steps: providing a sample containing a nucleic acid, contacting said sample with at least one forward primer and at least one reverse primer, wherein the at least one reverse primer hybridises within the β-tubulin nucleic acid sequence of Fusarium graminearum (Gibberella zeae) and comprises the nucleic acid sequence 5′-R1TTTTCGTX1GX2AGT-3′ (SEQ ID NO 1), wherein R1 comprises at least one nucleic acid residue of the β-tubulin nucleic acid sequence located upstream of the hybridisation site of the nucleic acid sequence SEQ ID NO 1 and subsequent to the nucleic acid sequence SEQ ID NO 1, X1 is guanine, adenine or inosine, X2 is cytosine, adenine or inosine, and wherein the at least one forward primer hybridises upstream of the hybridisation site of a nucleic acid sequence complementary to the at least one reverse primer, subjecting the sample contacted with the at least one forward primer and the at least one reverse primer to a nucleic acid amplification technique, and optionally determining the presence of Fusarium graminearum (Gibberella zeae) in a sample by detecting a nucleic acid amplification product.
