Done with Harvest? Collect Sample for SCN Analysis!

Soybean cyst nematode (SCN) is silently gaining territory in Ohio as SCN numbers are rising. The ability to reproduce on soybean cultivars with ‘SCN-resistance’ threatens Ohio soybean production. To take action, we need to know our numbers. Managing SCN begins with an adequate and correct soil sample. We are excited to continue sampling soybean fields in Ohio to test for SCN with funding from the Ohio Soybean Council and The SCN Coalition. Our goal is to sample more soybean fields, targeting those that have consistently been yielding low, under continuous soybean or double crop, and with weed issues. Fall is a great time to sample for SCN and we are excited to help with this task by processing up to TWO soil samples, per grower, to be tested for SCN, free of charge. For more information on how to sample for SCN and where to send these samples, please visit our article: ‘Collect Fall Soil Samples for SCN.’
