Jim Kurle gives talk about soybean seed, seedling and root rots at SWROC
"Phytophthora root and stem rot is problematic," Kurle said. "It is widespread in soybean producing areas across the U.S., and worldwide. In north central U.S., it is the second most damaging resulting in a yield loss of 42.2 million bushels alone in 1998."
Kurle said in Minnesota, phytophthora is responsible for yield losses approximately around 1 percent, but under the right conditions those losses can reach as high as 6 percent.
"Even worse, on an individual field basis, if it takes hold, losses of 50 to 60 percent have been seen," Kurle added.
