Scout Midsummer for SDS in Soybean Fields

Cool spring soils and high rainfall in areas of the Corn Belt could lead to appearance of Sudden Death Syndrome symptoms in soybean fields midsummer - according to DuPont Pioneer scientists. The severity of SDS depends on environmental conditions, time of infection and other crop stressors - scientists say - and can vary from field to field - which is why growers should understand the extent of an SDS infection in each field to effectively manage the disease. Scientists say growers should scout fields when disease symptoms are present. SDS leaf symptoms appear as yellow spots - typically in a mosaic pattern on upper leaves - and then coalesce to form chlorotic blotches between leaf veins. Infected leaves will twist and curl before they fall prematurely from the plant. Root symptoms include rotted roots with deteriorated taproots and lateral roots - with the root cortex discolored in a light gray to brown. If soil moisture is high - bluish fungal colonies can be present. These symptoms mean there’s reduced water and nutrient uptake. Visit www dot DuPont dot com (www.dupont.com) for more information.
