FIGHT PROFIT-REDUCING SCAB
WITH PROSARO FUNGICIDE.
®
Broad-spectrum Prosaro® fungicide offers unbeatable scab control and mycotoxin
suppression, giving you maximized yields and grain quality. Grow more profit with Prosaro.
WHAT IS SCAB?
•Fusarium head blight (FHB), or
scab, is an aggressive disease
which can affect grain quality and
reduce wheat yields. Scab thrives
in the conditions in which your
crop thrives.
•According to the U.S. Wheat and Fusarium head blight
Barley Scab Initiative, yield losses “tombstones” on wheat.
can exceed 50 percent and cost
nearly $300 million in profit during epidemics.
•Infected plants produce sterile flowers with kernels
that have a shrunken, chalky, white appearance,
nicknamed “tombstones.”
•The Fusarium pathogen overwinters in the residue from
corn or wheat crops, so crop rotation practices often
used to manage worm and insect pests aren’t effective
when it comes to scab.
•Corn-to-wheat crop rotation can increase
scab infection.
THE ISSUES WITH DON
•Scab can lead to contamination of a particularly
potent mycotoxin known as deoxynivalenol (DON).
•DON-infected grain is difficult or impossible to
market. The presence of DON reduces flour quality
for millers and may be unacceptable for malting
and brewing.
•In 2013, the Chicago Board of Trade lowered the
limits on the amount of DON in wheat that could be
shipped to 3 parts per million (ppm), and to avoid
price discounts the level can’t exceed 2 ppm.
In other words, even trace amounts of DON in your fields
can have significant impact on profits.
YIELD AND QUALITY PROTECTION
FROM PROSARO
Prosaro fungicide has two active ingredients to provide
broad-spectrum disease control of both leaf and head
diseases—especially of profit-robbing scab—to help
maximize yields, quality and profit potential.
•For outstanding scab-clean spring and winter wheat,
apply Prosaro at 6.5 fl oz/A.
•When applied at flowering—Feekes 10.51—Prosaro has
been shown to reduce DON by as much as 50-70%.

DISEASE MANAGEMENT
When evaluating fungicides as part of your management
practice to prevent and treat scab, it’s important to note that
not all fungicides are created equal.
•Strobilurin-containing products DO NOT control scab; in
fact, if applied too near early flowering stage, strobilurins
may actually increase DON levels.
•Scab can be present before symptoms are visible, so
fungicide application timing is critical.

•As the leading fungicide for fighting scab in the
U.S., Prosaro has been rigorously tested for the
performance of its two active ingredients.
•North Dakota State University rates the triazole
chemistry in Prosaro as “very good”—the highest
rating among fungicides in efficacy against scab.
UNTREATED
Few visuals illustrate the effects of scab on grain quality as well as a side-by-side comparison. The two loaves of
bread in this picture were made using the exact same recipe, baked at the same temperature and using all the same
ingredients—except for one. Flour made from scab-infected wheat that was contaminated with DON was used in the top
loaf. While the bottom loaf was baked with uncontaminated flour.
