SCN in Soybeans: Do I have an issue?

As I drove around Southern IL this summer, I noticed a lot of fields that have areas in them that were showing the symptomology of Soybean Cyst Nematode (SCN). Often these spots are stunted, yellow and just generally not in good health. Now, there are a lot of reasons for soybeans to show this symptomology, and very likely not every one of these spots were SCN, but SCN counts have been on the rise over the last few years and now is a great time to be testing for the pest. SCN, like all nematode species, is an unsegmented [...]

Use Your Toolbox to Control White Mold Infections

As the growing season progresses and we near harvest, Illinois soybean growers often see increased disease symptomology in their fields. They may wonder what can be done to combat diseases once symptoms appear, but with some pathogens the infection occurs many weeks prior to the onset of visible signs of disease. Once the infection is apparent, it is often too late for effective control. The best-known illustration of this is Sudden Death Syndrome (SDS), but white mold is another example. Figure 1 shows very early symptoms of the disease appearing in the upper canopy. Although it may be too [...]

If that wasn’t enough rain, then the 18 inches we received on our farm in July certainly was. Yes, you did just read “enough,” “rain,” and “July” in the same sentence.
