Soybean rust update

Soybean Rust Scouting Will Continue, but Scaled Down
The University of Missouri Extension staff will scout fields only in the southern part of Missouri. If signs of the disease indicate the pest is moving northward, the next set of Extension agronomists will scout fields in mid-Missouri.
The objective is to detect soybean rust when it first starts to develop in Missouri soybean fields so farmers can be warned about the presence of rust. Once the disease is detected, an all-out alert will be issued to farmers in the area of detection using media. Contact Allen Wrather, Plant Pathologist, Delta Center, wratherj@missouri.edu, for more information regarding this.
Individuals interested in more information about rust can go to www.sbrusa.net to view a map of the United States showing areas scouted for rust and areas were rust has developed.
Missouri farmers, dealers and crop consultants may have soybean leaves examined for rust at the University of Missouri Plant Diagnostic Clinic for a $15 fee. Soybean leaves should be placed in moist paper towels and sealed in a plastic bag and expressed mailed to the clinic along with a completed information form. The information form and more instructions about collecting and mailing samples to the clinic are posted at http://soilplantlab.missouri.edu. Allen Wrather, Plant Pathologist, 573-379-5431.
