Sudden Death Syndrome has contributed an annual yield loss of over $540,000,000.00/year throughout the United States since 2009 and is continuing to rise. It is the 4th yield robbing pest when it comes to soybeans, following soybean cyst nematode (#1), seedling diseases (#2), and charcoal rot (#3).

SDS is a soil-borne pathogen, meaning once it is present in a field it can easily be spread with soil movement. Sudden death syndrome is persistent in ALL soil types, and overwinters on corn, making traditional rotational practices less effective. The infection can occur at any time, however the first noticeable symptoms of sudden death syndrome occur at the R2 growth stage. When there are visual symptoms present, yield loss can exceed 70%, however even when there are no visual symptoms of sudden death syndrome, root rot can still cause a 20-30% yield loss. Currently our only fight against SDS is selecting resistant soybean varieties and reducing compaction.

On the bright side – help is soon on the way! Bayer CropScience has developed a new seed treatment, ILeVO – the only solution for sudden death syndrome on the market that has activity against nematodes. Based on the last 3 years of testing throughout the United States, Bayer research is showing a 2 bu/ac average yield increase when there are NO foliar symptoms of SDS present, and 4-10 bu/ac yield increase when SDS symptoms were present depending on the level of infection.

The photo below is showing yield differences between soybeans treated with and without ILeVO, as well as comparing SDS tolerant vs. Susceptible soybean varieties.

Look for additional information about ILeVO seed treatment coming soon! This is a very exciting product that could drastically increase your soybean profitability. Talk with your local Mercer Landmark Agronomist today about testing ILeVO on your farm.
