Dr. Damon Smith, University of Wisconsin-Madison, visits a soybean field that shows signs of low emergence due to soil crusting and Pythium seed rot. The field has experienced cool wet weather after planting.
Dr. Smith explains how to management is achieved through seed treatment or adjustments to planting populations. A target population on 140,000 seeds/acre applies to use of treated seeds. Without seed treatment, growers can adjust to a planting population of greater than 140,000 to make up for loses due to seed rot prior to emergence.
