Hi, my name is Travis Faske, University of Arkansas Division of Agriculture Extension Plant Pathologist. [Travis standing next to a soybean field.]
Today I’d like to share with you some recent information about soybean rust in the state. We’ve found that over about 19 counties within the state, all the way from the southern part of the state to the northern part of the state. Arkansas, Chicot, Cross, Drew, Desha, Greene, Jackson, Jefferson, Lawrence, Lee. Lincoln, Lonoke, Mississippi, Monroe, Phillips, Prairie, Randolph, White and Woodruff counties.

The number of counties similar is to what we saw in 2012, which was about 20 in mid-October. Most of this positive identification has come on R7 or R8 soybeans, which is well past any stage to spray a fungicide. [Pictures of soybean leaves with soybean rust.] This is a point to let growers know that it did return to the state late in the season again. For it to come in again next year, it’ll have to start again somewhere in the Caribbean to Louisiana or Mississippi before it moves this way into Arkansas.
