Database Research Summaries2018 Soybean Cyst Nematode Sampling Program
Research Focus
The focus of this project is to continue sampling SCN management tools that help North Dakota producers.
Objectives
- Provide incentive for growers to sample for SCN by covering the cost of up to three SCN samples.
- Create a SCN distribution map that can be used to determine how widespread SCN is.
Results
- 710 samples were received in the fall of 2017. 237 of the 710 samples were positive (approximately 33%) and egg counts ranged from 50 eggs/100cc to 55,400 eggs/100cc. Notably, very low egg counts (50 or 100 eggs/100cc) could be false positives.
- In 2017, a notable increase in samples from Grand Forks County were recorded, but while some egg counts in the county were very high most were negative. Enough data points were collected from 2013 to 2017 that ‘heat maps’ were created for the southeast and south central counties in North Dakota.
Importance
- Early detection of SCN is critical to avoiding yield loss.
- Secondary benefits of this program have occurred, including the increased talk among growers about SCN, many press interviews and importantly, a significant amount of positive press for the NDSC and its mission to serve the ND growers.
