Soybean cyst nematode (SCN), Heterodera glycines, is a key pest of soybeans in Michigan (MI). While there are management options such as resistant varieties, seed treatments, and crop rotations, there is a distinct need for additional control practices. This is particularly important to the prevention of the development of highly aggressive populations related to the extensive use of cultivars derived from the PI88788 source of resistance. Cover crops are being used in agronomic systems to manage weeds and enhance soil health issues, however, very little is known about their impact on SCN. In addition, specific cultivars are successfully used as trap crops for management of sugar beet cyst nematode (BCN), H. schachtii. The objective of this research was to evaluate selected plant cultivars for their potential as cover or trap crops in soybean production . In 2016-2017, a total of 17 experiments related to this project were conducted under greenhouse conditions and field locations in MI (Ingham, Monroe, and Cass counties). Eleven cultivars, representing two families (Fabaceae and Brassicaceae), were evaluated in the greenhouse experiments. Six were selected for the field experiments. A cover crop blend with trap crop germplasm was included in 2017. All trials included a SCN susceptible and SCN resistant soybean cultivar, as well as a fallow treatment. After 45 days, all cultivars evaluated in the greenhouse experiments had egg and cyst population densities lower than the susceptible control. This was not always true in regards to the number of eggs/cyst, which were not significantly different from the susceptible control. During 2016 in Monroe and Cass counties, all cover crop cultivars resulted in fewer eggs, cysts, and eggs/cyst, compared to the susceptible soybean control. Ingham country in 2016, however, there were significant differences between the cover crop cultivars and the susceptible control for three SCN life stage indicators. In 2017, only Cass County experienced population changes from the treatments with similar results to 2016. A three-species cover crop blend containing a PI437654-derived trap crop is being evaluated in 2018 in Michigan under three different commercial soybean production systems . While progress has been made in our research in regards to identification of a trap crop for SCN management, more experimentation needs to be done to determine if these cultivars are trap crops or only poor or non-hosts. A supply of pure PI88788 has been obtained and will be given to a seed company for increase for use in future CN trap crop research in Michigan.
