Now's an Opportune Time to Scout for SCN July 25, 2018

July through August is a good time to check soybean fields for soybean cyst nematodes (SCN), the most devastating pest for soybean growers. Yield losses of 25-30% have been documented in fields with no visible injury on the soybean plants.

Improving Soybean Profitability: SCN March 3, 2017

The easiest and least expensive way to improve profitability for many soybean growers in tight economic times, or any time, is to sample fields for soybean cyst nematodes (SCN). In Nebraska trials growers realized an average six-bushel-per-acre soybean yield increase after taking no-cost steps to manage SCN.

Test for SCN This Fall & Select Seed Accordingly October 31, 2016

If you noticed some areas of your soybean fields that didn't yield as well as expected, this fall would be a good time to soil test for soybean cyst nematode. In University of Nebraska research of SCN-infested fields, switching to an SCN-resistant variety increased yields as much as 6 bu/ac.
