Tan spot, caused by Pyrenophora tritici-repentis, and fusarium head blight (FHB), the Fusarium graminearum species complex, are among main wheat diseases worldwide. This 3-year field study evaluated effect of soil incorporation calcium silicate, a source silicon (Si), to manage tan spot FHB improve grain yield quality. The Si was compared on two cultivars contrasting in disease resistance assoc...

Abstract In recent years, tan spot of wheat caused by the fungus Pyrenophora tritici-repentis has become more prevalent in Oklahoma. Experiments were conducted to investigate race structure, disease symptoms and genetic variability P. isolates collected from winter over three decades. Race determination was for 16 based on expression necrosis and/or chlorosis produced differentials. Variability...

Abstract Reduced tillage is considered as one of the main tools to save biological diversity; however, it increases pressure diseases, including wheat leaf blotches. The aim present study was clarify impact reduced soil on development winter blotches in different schemes crop rotation. growing technologies severity disease evaluated a two-factorial experiment: A – system, and B combinations pre...
