Impact of Crop Rotation and Soil Tillage on the Severity of Winter Wheat Leaf Blotches

Reduced tillage is considered as one of the main tools to save biological diversity; however, it increases pressure of diseases, including wheat leaf blotches. The aim of present study was to clarify the impact of reduced soil tillage on the development of winter wheat leaf blotches in different sch...
