Watch Out for Early Season SDS

This agronomic image shows sudden death syndrome in soybean leaves.

Don’t let yield robbers like sudden death syndrome (SDS) get the best of your soybean fields this year. One of the most destructive soybean diseases, SDS affects the majority of soybean-growing areas.

What is SDS?
Caused by the soil-dwelling fungus Fusarium virguliforme, SDS thrives in cool, moist conditions, putting early planted soybeans at risk. SDS is often found in fields also infested with soybean cyst nematode (SCN) because SCN feeding damages roots and creates gateways for this pathogen to infect the plant.

What causes SDS?

The University of Nebraska notes that early-planted soybean fields – especially when coupled with a history of severe SDS – are more likely to be at risk for the disease. SDS occurs most frequently in fields planted back-to-back with soybeans, according to University of Missouri Extension.

How do you treat SDS?

Since there are no in-season treatment options for SDS, now is the time to get ahead of this challenge. Planting varieties with resistance to SDS, like many NK® Soybeans, will equip fields with a foundation of protection.

Growers can also apply seed treatments to help further protect seeds from SDS during the early stages of development.
