The fungus Pyrenophora teres Drechsler (anamorph Drechslera teres [Sacc.] Shoem.) is the causal agent of net blotch of barley (Hordeum vulgare). Similar to other stubble-borne diseases, net blotch has become economically important and has emerged as a major disease in many barley-growing areas worldwide. Pyrenophora teres f. maculata (Ptm) is a fungal pathogen that causes the spot form of net blotch on barley and leads to economic losses in many of the world's barley-growing regions. Isolates of Pyrenophora teres, causal agent of net blotch of barley, exists in two forms, designated P. teres f.teres and P. teres f.maculata, which induce net form net blotch (NFNB) and spot form net blotch (SFNB), respectively.Significantly more work has been performed on the net form than on the spot form although recent activity in spot form research has increased because of epidemics of SFNB in Pyrenophora teres, causal agent of net blotch of barley, exists in two forms, designated P. teres f.teres and P. teres f.maculata, which induce net form net blotch (NFNB) and spot form net blotch (SFNB), respectively.Significantly more work has been performed on the net form than on the spot form although recent activity in spot form research has increased because of epidemics of SFNB in Spot form of net blotch (SFNB), caused by the fungus Pyrenophora teres f. maculata, was first described in Denmark in the 1960s and is now a prevalent foliar disease of barley in many countries. Net blotch, induced by the ascomycete Pyrenophora teres, has become among the most important disease of barley ( Hordeum vulgare L.). Easily recognizable by brown reticulated stripes on the sensitive barley leaves, net blotch reduces the yield by up to 40% and decreases seed quality.
