With the delays in planting this year it is possible that growers will be switching out of other crops in favor of soybeans. Soybean Cyst Nematode (SCN) is the most problematic soybean disease in the United States, and has been confirmed in six counties in North Dakota.
If you are considering planting soybeans to an area you suspect/know has SCN it is very important to select a resistant variety. A resistant variety will pay dividends twice: by increasing yield in the current year and by limiting a spike in egg counts that will impact yield in future years.
If you have been using resistant varieties already, try to purchase a variety with a different source of resistance (rotate PI88788 to Peking for example). However, if this is not possible, purchase a different variety than used the last time soybeans were in the ground, even if the same source of resistance is the same. There is variability within the sources of resistance, so variety X with PI88788 may act differently to the nematode than variety Y with PI88788. Rotation of sources of resistance will prolong the effectiveness of our resistance genes on your farm, and allow for more successful management of SCN.
