[Fhb-update_ma] FHB Update from PA, 05/06/19

[FHB Updates - Mid Atlantic SWW Region]

Recent wet and mild weather is driving up scab risk across Pennsylvania.
Keep a close eye out for anthers emerging from progressing wheat and
consider your spray decisions. Sprays prior to heading do not suppress scab,
but one labeled fungicide, Miravis Ace, may be applied at 50% heading. The
best control with all fungicides will result from spraying at the first sign
of anthers. Caramba and Prosaro (Group 3) or Miravis Ace (Group 3 + 7), give
good control of scab as well as most leaf and head diseases. They do not
need to be tank mixed with another product to control these diseases. Spray
nozzles should be angled at 30° down from horizontal, toward the grain
heads, using forward- and backward mounted nozzles or nozzles with a two
directional spray, such as Twinjet nozzles.
