Distribution of races of <I>Pyrenophora tritici-repentis</I> in Algeria and identication of a new virulence type

Tan spot, caused by Pyrenophora tritici-repentis, is a foliar disease  of wheat, responsible for high economic losses in several wheat  growing areas in the world. There are eight known races of P. tritici-repentis based on ability to induce necrosis and/or chlorosis on a set of differential cultiva...
