 The
National Sunflower
Association (NAS) partially funded a research project with
Dr. Sam Markell of NDSU and others on fungicide timing and
control of red rust in sunflower. There were three research
sites all in North Dakota. There were nine treatments including
the untreated control.
Markell concluded that there was a "clear differentiation
between the effectiveness of fungicides and the timing of
applications".
There was a difference in the most effective timing between Qol
fungicides like Headline® and Quadris® and the triazole family
of fungicides which includes Folicur®.
The fungicides in the two classes do not work equally on
sunflower rust. Markell concludes that in these trials "a single
well-timed application of an effective fungicide was as
effective at reducing sunflower rust as multiple applications."
