From the road, it looks like white mould and/or SDS symptoms. In this situation, you can use a knife and carefully cut and inspect the stem to determine the disease. BSR infected plants will have their stem infected, hence the disease name. Often, it looks like “stacked brown pennies” inside. Compared to other diseases that do not have the stem affected, this is a key way to tell it is BSR. Do not get fooled. Knowing what reproductive season disease(s) you have will help you decide what seed agronomic traits to look for when buying next year’s seed. Every soybean variety has its own agronomic strengths and weaknesses. As an example, some varieties have stronger scores on white mould, while differing on other disease scores mentioned above or vice versa. Scouting your fields and being an agronomy detective will allow you to plan field-by-field soybean varieties that are suited to not only your management practices, but the disease present in that field. A little planning goes a long way, for a higher success rate in the future based on historical diseases present. Root Rots Adding to the multitude of diseases found later in the season, 2023 saw a cool, wet growing spring, followed by rapid growth in June, with prolonged wet soil cycles. This was ideal for various root rots. Sometimes root rots are hard to diagnose once you see them. Once one disease takes hold, other predatory-style diseases join in. With multiple roots rots taking place, a simple lab diagnosis using DNA multiscan helps. In our area we were seeing fusarium, rhizoctonia, pythium and phytophthora root rot showing up more than other years. Look carefully at disease scores when selecting soybean seed for early root rot disease as well as seed treatments. There are differences in seed treatment products on the market. Gone are the days of simply saying, “I have seed treatment on my seed; I am good to go.” Reach out to your trusted agronomy supplier and discuss more strategies for managing each disease. It may seem like it is an overwhelming task taking on soybean diseases. A little planning and understanding on how, when, why and where the disease strikes goes a long way to helping control that disease down the road. Be a crop-scene detective in 2024. Happy sleuthing and seed planning this winter – and in the future – for disease-free fields and higher yields. BF Soybean disease
