摘要

Resistance has become a bit of a dirty word for soybean farmers and certain herbicides. Now, farmers in the Midsouth are learning resistance can also be tied to popular strobilurin fungicide chemistry used for controlling foliar diseases like frogeyeleaf spot (Cer-cospora sojina). The soybean disease, which flourishes in warm, humid conditions and is characterized by "frogeye-like" spots primarily on leaves, has developed resistance to strobilurins (http:/1bitjy IxghjYI) in geographic pockets of three states. "Scientists have confirmed resistance to strobilurin fungicides in some potato and sugar beet pathogens, and now we have found resistance in a soybean pathogen in five soybean fields in western Tennessee, western Kentucky and southern Illinois," says Carl Bradley, University of Illinois Extension plant pathologist. Since 2008 he's been leading a fungicide-resistance monitoring program funded by Illinois soybean checkoff dollars.
