Although it’s difficult to execute, several researchers are undertaking the laborious task of exploring how root health ultimately impacts yield potential. Consistently wet weather in recent years, coupled with the upsurge in adoption of reduced tillage programs, has increased the presence of certain yield-robbing, soilborne pathogens, such as Rhizoctonia, Pythium and Fusarium, in critical U.S. wheat-producing regions. “These root diseases can be referred to as ‘root nibblers,’ or hidden diseases and can have a huge impact on yield potential,” explains Dr. Wayne Pedersen, emeritus plant pathologist, University of Illinois. “Incidence of these soilborne pathogens has increased steadily with evolving production  practices, such as no-till, and the cool, wet weather we’ve experienced the past several spring seasons.”
