NEMASPHERE SCN RESISTANCE TRAIT

SCN is a leading cause of soybean yield loss in the U.S.  A challenge facing producers with SCN-infested fields is that this soil-borne pathogen can impact yield with no or few visible aboveground symptoms.

Management options for SCN include planting resistant varieties and rotating soybeans with a non-host crop such as corn.  However, the effectiveness of planting resistant varieties is declining because most SCN-resistant varieties use the same resistance source that is being adapted to by SCN populations.

In a June 2024 News article titled “BASF unveils Nemasphere nematode resistance trait, the new standard of nematode management for soybean farmers”, the originating company presents information about the first and only biotech trait developed for control of SCN.  This transgenic trait uses a novel Cry14 protein that interferes with nutrient uptake in the intestines of the nematode when it is ingested.

Nemasphere is a single-locus trait that will enable breeders to incorporate it into a full range of forthcoming soybean varieties with no expected yield drag. The trait will be stacked with BASF’s Enlist E3 weed control technology.  It should provide an additional level of SCN control when used with other control measures such as those listed above.

Pending regulatory approval, Nemasphere is anticipated to be available in 2028.
