CRITICAL APPLICATION TIMING Prosaro® Fungicide Disease Control—to Help Maximize Yield and Quality Prosaro® : 6.5 to 8.2 oz/a + NIS 0.25% v/v (1 qt/100) • Powerful activity on leaf and head diseases for broad‑spectrum control, better grain quality and improved profit • Apply at the T3 timing—early flowering in wheat and full head emergence in barley—to help optimize protection Why T3 Timing Instead of T2 (flag leaf) Timing in Cereals? • Research in the Northern Plains has shown that leaf disease problems (particularly leaf rust) coincide with head scab disease development* • T3 timing is typically the optimum time for control of leaf and head diseases (stripe rust and powdery mildew may be exceptions) • T2 timing (flag leaf) is too early to protect the head and florets from disease • Residual control from T2 sprays may not protect against late leaf infections * Data Source: J.J. Wiersma and C.D Motteberg, Can. J. Plant Pathol. 27:25‑37 (2005)
