Comparing Yields and Nematode Control of Soybean Varieties with Different Sources of SCN Resistance in Strip Trials

摘要

The primary method of managing yield loss due to the soybean cyst nematode (SCN) is through the use of resistant soybean varieties. Most SCN-resistant varieties available in Iowa have the PI 88788 source of SCN resistance. There are concerns that over time, SCN will be able to overcome the PI 88788 resistance.
