Now is the time for farmers to start checking their soybeans for any damage from Sudden Death Syndrome (SDS). Iowa State University Researcher Alison Robertson says the disease starts appearing the last week of July into the first week of August. The common symptoms are the leaf tissue between the veins will turn bright yellow, then brown and die where plants are in a compacted area.
Robertson says the disease comes from a fungus that lives in the soil that first appeared in Arkansas in the 1960s and has been slowly spreading. She adds SDS has been a problem in southeast Iowa for the last three or four years.
Robertson notes if you should find an infected plant, the plant is a loss for this year and recommends growing a resistant variety in that field and monitor for soybean cyst nematodes. For more information about soybean Sudden Death Syndrome, follow the link here.
