Brief Project Summary:

Heterodera glycines, better known as the soybean cyst nematode (SCN), is the most damaging pathogen of soybean in the North Central Region of the USA. This nematode is particularly problematic because viable eggs can persist in the soil for years, making this disease difficult to manage. A control strategy that would limit SCN egg hatch would be the most effective way to disrupt a critical point in the nematodes' life cycle. Commonly used nematicides do not kill nematode eggs, but newly discovered SCN viruses reproduce in nematode eggs and lower their viability. The goal of this project is to quantify the extent of damage SCN viruses inflict on the nematode in laboratory and field SCN...

Information And Results
Project Deliverables

Our main goal is to quantify the damage that viruses cause on SCN. We will quantify the damage to SCN in both the field and in laboratory experiments. For the field phase of the project, the first goal will be to identify and locate virus-infected SCN populations. The next step will be to assess the extent of damage to SCN reproduction caused by the viruses. In the laboratory studies, we will utilize inbred SCN populations with differing levels of the viruses or no virus at all. These studies will be ongoing throughout the first year and should establish the level of damage to egg hatch rates and nematode mobility.

Final Project Results

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
