Foliar, Stem and Head Diseases

Avoid growing barley after barley, wheat or grasses. Plow-down stubble and straw and plant early to avoid serious disease in July.

azoxystrobin + propiconazole - Quilt

Comments (Days to harvest, label precautions, etc.)
Ground and aerial application. Apply once between stem elongation (Zadok’s 29–37) and half head emergence (Zadok’s 49–55). Maximum 1 application/season. 45 days to harvest for grain or straw. Do not harvest for forage. When expecting high disease pressure from stripe rust, use the higher application rate of 1 L/ha.
