[Fhb-update_ma] FHB Update from PA, 05/31/16

[FHB Updates - Mid Atlantic SWW Region]

Wheat continues to flower in the central and upper portions of PA. Scab risk
is increasing in some of these areas, especially the west and the upper
central regions. Be prepared to spray a fungicide on fields that are at the
beginning of flowering, up to about 5 days following the beginning of
flowering. Remember, sprays applied PRIOR to flowering will NOT provide
significant suppression of scab or toxin production. Caramba or Prosaro are
effective on scab and give control of most leaf diseases and glume blotch.
They do not need to be tank mixed with another product to control these
diseases. Do NOT use any strobilurin-containing fungicides at heading or
beyond.
Growers whose wheat flowered two to three weeks ago may begin to observe
scab symptoms in the next week. Check out this week’s PSU Field Crop News
for tips on identifying head diseases and how to proceed if you have them.
