The 2015 survey of early-vegetative soybeans found 38% (19 of 50) surveyed fields tested positive for Phytophthora root rot disease caused by Phytophthora sojae. That is a lower infection level than last year’s 49%, but still very high. The state-wide survey took place from June 2 to 30. The fungus-like pathogen was detected in 16 counties: Buffalo, Calumet, Chippewa, Columbia, Dodge, Dunn, Iowa, Kenosha, Lafayette, Manitowoc, Outagamie, Polk, Rock, and Winnebago. Based on previous year’s survey results, all other counties should not expect to be free from the disease.
