Prosaro is a fungicide for wheat and barley that provides powerful control of leaf and head diseases. It increases yields and grain quality by reducing diseases like Fusarium head blight and associated mycotoxin levels. Prosaro has shown effective control of many diseases in wheat including rusts, septoria leaf spot, and glume blotch. When applied at early flowering stages, Prosaro can reduce DON levels in wheat by over 2 ppm and in barley by nearly 4 ppm compared to untreated crops. This leads to higher quality grains that meet market standards.

3. Powerful Disease Control
 When applied at the appropriate timing, Prosaro
offers:
 Powerful activity on both leaf and head diseases
 Preventive and curative action against leaf
diseases
 Strong performance in spring and winter wheat as
well as barley
 Prosaro is the standard for preventive treatment of
scab (Fusarium head blight or FHB), with
outstanding foliar disease control.
 Reduces scab
 Suppresses DON levels

4. Powerful Disease Control
 Prosaro stops the penetration of the pathogen into
the plant and stops the spread of infection within the
plant. As a result, Prosaro inhibits the reproduction
and further growth of fungus.
 Prosaro stops existing fungal development and
protects against new infections on the treated plant
tissue. It does this without increasing mycotoxin
production in grain.

5. Powerful Disease Control
Most major leaf and head diseases are well controlled by timely
applications of Prosaro.

The Presence of DON
 DON, also referred to as vomitoxin, is a mycotoxin that is sometimes
produced in wheat and barley grain infected by scab.
 Scab is most prevalent when wet weather occurs during the
flowering and grain-filling stages of plant development. The
occurrence of scab does not automatically mean that DON will be
present, but it does increase the odds dramatically.

7. Increased Grain Quality
The Effect of Strobilurins
 Strobilurins applied after flag leaf emergence may increase DON
levels, whereas Prosaro brings DON levels down.
 ―Fungicides that contain an active ingredient in the ‗strobilurin‘ class
should NEVER be applied to control FHB. This includes products like
Headline®, Quadris®, Quilt® and Stratego®. Research has shown that
strobilurin fungicides can actually increase DON levels in harvested
grain. These strobilurin products are very good at controlling foliar
diseases of wheat, and if used, should be applied earlier in the
season (around Feeke‘s 8—flag leaf emergence).‖

Regulating DON
Wheat
 Recent regulatory changes from the Chicago Board of Trade lowered
the acceptable level of DON without price discounts from 3 ppm to 2
ppm. These changes mean that even trace amounts of DON in your
fields can have significant impact on the grains‘ marketability.
Barley
 Tight malt restrictions mean even trace amounts of DON in your fields
can have significant impact on barley grains‘ marketability.

 Donald J. Reid (ret.), TAMU-C
 Dr. James S. Swart, Texas AgriLife Extension
 Stripe rust conclusions
 Begin scouting fields at Feeke‘s Growth Stage 7

26. Application Recommendations
 Why adjust the spray tips?
 Dye studies were conducted at the NDSU Langdon Research Extension
Center (S. Haley, G. Van Ee, et al.) and SDSU (B. Ruden).
 Forward-facing nozzles were compared with vertical-oriented nozzles.
 Approximately 2X amounts of dye were collected on the heads treated
with forward-facing nozzles.
 Prosaro needs to be on the heads to prevent scab infections.
 Control of leaf diseases is not compromised.
