The end of the field season is near and many producers are likely to spend some time watching the yield monitor as they harvest. This time is a great opportunity to identify spots in the field with unexplained yield loss.
A potential explanation for these areas could be soybean cyst nematode.
This pest is the number one yield-limiting biotic agent of soybeans in North America and is estimated to cost U.S. producers $1.5 billion a year.
The reason this pest is so insidious is because SCN can cause up to 30% yield loss with no significant above-ground symptoms.
For this reason, SCN is an invisible threat that many producers do not know they have and are not actively managing it in their fields.
As of Jan. 1, 2022, SCN has been identified in 59 Nebraska counties. Fortunately, effective management options are available, but the first step in deciding to manage is to determine if the nematodes are present in your field.
The best time to test fields for SCN is at the end of the soybean season. This is when SCN levels will be at their highest in the soil.
