Soybeans face yield-robbing threats in August

Sudden death syndrome in soybeans is being reported in many locations across the Midwest.
Todd Claussen, director of agronomy for Ames, Iowa-based Landus Cooperative, says infected beans will shut down early.
“They’ll senesce early and they’ll drop leaves faster,” Claussen says. “You can’t do anything with it now, but as you move into next season you have to think about the history of a specific farm. One, you start with genetics—and two, you can treat with a soybean seed treatment that is highly effective.”
Another threat to soybean yields is soybean aphids. Claussen says they’re starting to show up in greater numbers.
“Aphids like it mild. They like 77-78 degrees—their reproduction will go through the roof if that be the case,” he says. “We are ramping up and have expectations to pull that trigger here rather soon.”
White mold is also on their radar, Claussen says.
