The soybean cyst nematode (SCN) remains the most devastating and yield limiting soybean pathogen in Ohio and North America. SCN can cause over 30% yield reduction with no visible symptoms, therefore, early detection of this pathogen relies on testing your fields to know your SCN numbers!
Spring is a good time to sample for SCN. A soil test in spring will reveal if SCN is present and if so, at what levels. If you are planning to participate in an on-farm trial that requires soil sampling, a subsample can be used for SCN testing. Additionally, if you planted corn, a soil sample from that field will reveal if you have SCN but most importantly, how much SCN. Knowing your SCN numbers will help you determine the best management strategy.Read More »
