Sudden Death Syndrome Showing Up in Missouri Soybean Fields
Ed Brown, MU Regional Agronomist
Sudden death syndrome (SDS) of soybean is caused by the soil-borne fungus Fusarium virguliforme and is showing up in the area as affected individual plants or small clusters of plants within fields. Fortunately, the disease is occurring relatively late in the growing season and significant yield losses are not anticipated this year.
Symptoms appear as yellow and brown discoloration between leaf veins, with veins remaining dark green. Additional symptoms include severely rotted root tissue and a light brown discoloration (normally cream colored) of the outer stem tissue when the stem is sliced in half with a knife.
The name sudden death syndrome is a misnomer because the disease doesn’t appear suddenly and doesn’t always result in death of the plant. SDS typically appears when growing conditions have been relatively favorable and there has been abundant soil moisture throughout most of the growing season. These saturated soil conditions favor infection of root tissue by the fungus, especially in susceptible varieties. In most growing areas of south-central Missouri, the 2013 growing season has been marked by abundant rainfall and often saturated soils through mid-August, contributing to higher levels of SDS.
Planting a resistant variety is the best method of controlling SDS; examine university and private company ratings and choose those varieties with the highest level of resistance to this disease together with those varieties exhibiting the highest yield potential. Spraying with a fungicide will not reduce the incidence of SDS and is not recommended.

Don’t guess; soil tests save time, money
Soil testing is the best guide to the wise and efficient use of fertilizer and soil amendments, said Manjula Nathan, director of the University of Missouri Extension Soil Testing and Plant Diagnostic Services.
Whether you grow acres of row crops or have a vegetable patch in the backyard, a soil test will provide you with an analysis of nutrients and a set of recommendations for any improvements.
“We frequently get questions from customers like, ‘I apply fertilizer every year. How come my plants are not doing well?’” Nathan said.
“Most of the time the problem is they never have done a soil test, but have been guessing on fertilizer requirements,” she said. “They do not realize that by guessing they are wasting money by over- or under application, and the excess fertilizer can end up in streams, ponds and underground water, polluting the environment.”
Soil testing can be done through the extension office. Soil tests cost $15 per sample during the first full week of the month and are $16.50 per sample otherwise. Six or more tests are $12.50 per sample. Make sure your soil is dry when you bring it in. A soil probe and a auger that can be checked out from the extension office. There is a $50 deposit on the soil probe. Soil testing publications
