Error concerning three varieties in 2016 Soybean Update |
Author: Terry Kirkpatrick, Professor - Plant Pathology |
By Terry Kirkpatrick, Extension Plant Pathologist *SOYBEAN UPDATE ERRATA* I want to alert you to an inaccuracy in the 2016 Soybean Update root-knot nematode ratings. The cultivars REV 45A46, REV 48A26, and REV 48A76 are incorrectly listed as resistant. All three cultivars are, in fact, susceptible to root knot nematodes. We apologize for any confusion […]

The Sudden Death Syndrome (SDS) in your soybean field may be trying to tell you something!

Soybean nematode survey opportunity: Check for the hidden enemy of soybean |
Author: Terry Kirkpatrick, Professor - Plant Pathology |
Nematodes have been called the “hidden enemy” of soybean because these soilborne, microscopic root pathogens can go unnoticed in a field until yield losses become severe. The number of soybean fields showing visible damage due to nematodes has increased dramatically during the last few years statewide, and most of the time the root-knot nematode is […]

Phytophthora root and stem rot (PRSR) of soybean is a disease that can be a significant problem in wet years such as we are having this year. Cooler-than-normal temperatures, frequent rainfall, and poorly-drained soil favor this disease. PRSR is caused by the oomycete Phytophthora sojae, a soilborne plant pathogen that can survive for years in […]
