Managing wheat disease is goal of Kansas State University team

K-State team develops map ( that reflects the initial sampling of wheat fields in the spring of 2013. Sample sizes varied, from 10 to many aphids.

A Kansas State University team of researchers, extension specialists and agents is working with wheat producers to determine what percent of the aphid populations in Kansas have the potential to transmit yield-robbing barley yellow dwarf (BYD) into Kansas wheat. The hope research will help them understand and improve management options for BYD.

“Every spring when the BYD symptoms start to show up, there is always concern around the state that there is more of the disease than expected despite that we never saw plants covered with aphids,” said Jeff Whitworth, K-State Research and Extension entomologist. “However, it only takes one infected aphid to infect one or possibly more plants.”
