Foliar, Stem and Head Diseases

Leaf rust spores are blown in from the U.S. and in most years late-planted fields are most likely to show the disease. Alternate host is barberry. Remove or destroy alternate host from fence rows, etc. Plant early.

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.

Comments (Days to harvest, label precautions, etc.)
