Abstract excerpt

The fungal pathogen Pyrenophora teres f. sp. maculata (Ptm), responsible for spot-form of net blotch (SFNB), is currently the most significant disease of barley in Australia and a major disease worldwide. Management of SFNB relies heavily on fungicides and in Australia the demethylase inhibitors (DMIs) predominate. There have been sporadic reports of resistance to DMIs in Ptm but the mechanisms remain obscure....
