- Desha County soybean rust finding is first in Arkansas, most northerly finding in United States.
- Dry conditions likely to keep soybean rust on a short leash.
A small amount of soybean rust was detected Tuesday (July 31) in a field near Rohwer, Ark.
There are no recommendations to apply fungicides at this time, said Travis Faske, Extension plant pathologist.
“This is the first report of soybean rust this year in the state, and is about one week earlier than 2009, the last time it was reported in Arkansas,” Faske said. “This is the farthest north soybean rust has been confirmed this year in the U.S.”
Disease severity was low with an average of five pustules per leaflet, and disease incidence was extremely low in this field. Other small pockets of the disease are likely to be found, “but there is a low risk of disease progression due to drought conditions that cover much of the state and with the forecast for hot, dry weather.”
Plot monitoring will continue, Faske said.
