Abstract
Calonectria ilicicola is a soilborne fungus responsible for red crown rot (RCR) in soybeans. Recently, this disease has been detected in new areas within the United States and Asia, where it has been reported to cause significant yield losses. To date, no data on the efficacy of fungicide seed treatments for suppressing RCR in soybeans are available. We screened three commercially available soybean seed treatments (Acceleron STANDARD; Acceleron STANDARD + IleVO; Cruiser MAXX + Saltro) for impacts on germination, seedling growth, and disease caused by C. ilicicola under controlled laboratory conditions. The Cruiser MAXX + Saltro treatment improved final plant dry mass to levels similar to noninoculated controls. Both Acceleron STANDARD + IleVO and Cruiser MAXX + Saltro reduced percent root rot. Acceleron STANDARD alone did not impact root rot, indicating that the IleVO component was efficacious on C. ilicicola. These data indicate that IleVO and Cruiser MAXX + Saltro have potential for reducing early season impacts of RCR in soybeans. Future work assessing these seed treatments in field-grown soybeans is needed to better understand the role of seed treatments as components of an integrated management program for RCR.
