Improving wheat resistance to tan spot caused by Pyrenophora tritici-repentis
Tan spot caused by Pyrenophora tritici-repentis (anam. Drechslera tritici-repentis) is a foliar disease that has become a major component of the leaf spotting complex in Australia, Canada, the USA and several European countries in recent decades. Tan spot is also found in Argentina, Brazil, Mexico, Nepal, North Africa and Central Asia (Kazakhstan and Tajikistan). Severe tan spot epidemics tend to cause 10-20% yield losses, and may cause losses of over 50% under conditions favorable for disease development. Intensive wheat production, reduced tillage practices, susceptible varieties, and shorter crop rotations have contributed to tan spot epidemics in many regions.
