An annual threat to Minnesota’s wheat crop is moving from the Great Plains toward the North Star State. University of Minnesota Extension agronomist Jochum Wiersma says the first traces of “stripe rust” were recently found in southern Minnesota:
“Stripe rust is a disease that has been pretty prevalent in the southern winter wheat states, and we’ve had some southerly wind events bring this up and so its not necessarily spring wheat right now, but I would definitely start looking at rye and in the case of stripe rust, winter wheat fields.”
Stripe rust is also called “yellow rust” even though the striping is more orange in color. Wiersma says most wheat varieties have resistance to stripe rust and select fungicides are effective in eliminating the threat.
