Death before, at or following emergence. Stem collapse observed at the soil line. Thin uneven stands. Often confused with wireworm damage. Most noticeable following prolonged periods of cool, wet weather after planting. More severe in poorly drained soils. All corn seed comes pretreated with captan, fludioxinil, metalaxyl, and/or mefanoxam. Additional over-the-top treatments can be used when planting conditions are severe.
