Sudden Death Syndrome (SDS) is a disease that impacts soybeans in a big way. This disease will attack plants fast with little to no symptoms. This really plays a big role in food production because of the unexpected yield loss that may occur. By the time a farmer or agronomist may catch it, it is probably too late to treat and for it to be a successful treatment.
The global impact will not be severe on field to field bases, but if it becomes a state to state problem then it will really show an impact. United States moves a lot of soybeans out to feed other countries such as China and India. So losing yield can add up quick. The world is growing is population fast, and we need to be efficient as possible and that means not having disease. SDS will not help feed the world but contribute to food shortage.
There are a couple of ways to prevent this from becoming a problem for soybeans. Crop rotation is a key to keeping the disease down but also with residue management and not keeping infected residue in the area. These management strategies will not stop the disease but simply prevent it from getting worse.
