Abstract

Interaction Between Seed Treatment and Variety on Sudden Death Syndrome Symptoms and Soybean Yield

Highlights

The fungus Fusarium virguliforme, which infects plants through the roots, primarily before they start to flower, causes soybean Sudden Death Syndrome (SDS)
The presence of soybean cyst nematode (SCN) and saturated soils has been implicated in contributing to the severity of the disease
Selecting varieties with some degree of tolerance to SDS has been the primary cultural practice to reduce yield loss to SDS. Another tool to reduce yield loss to SDS has been made available to growers with the release of ILeVO seed treatment from Bayer CropScience (Research Triangle Park, NC)

Summary

Sudden Death Syndrome (SDS) is a soybean disease that perennially limits yields in the Kansas River Valley (KRV). Selecting varieties with some degree of tolerance to SDS has been the primary cultural practice to reduce yield loss to SDS. Another tool to reduce yield loss to SDS has been made available to growers with the release of ILeVO seed treatment from Bayer CropScience (Research Triangle Park, NC). The potential benefit of ILeVO on varieties with different levels of tolerance to SDS was examined in a study conducted at the Kansas River Valley Experiment Field in 2015. Treatments with ILeVO reduced the severity of SDS more and the yield increase was greater, up to 6 bu/a with varieties more susceptible to SDS
