Brief Project Summary:

Phytophthora root rot (caused by Phytophthora sojae) can be a destructive disease of soybean in years in which rainfall and wet soils are abundant. Management of this disease is accomplished primarily through the use of resistant varieties that utilize either single resistant genes (known as Rps genes) or partial resistance (sometimes referred to as “field resistance” or “tolerance”). The use of Rps genes over time has allowed for the selection of races of P. sojae that can overcome specific Rps genes, rendering these resistant genes ineffective. Understanding the diversity of P. sojae races in Kentucky can help soybean farmers make better choices when selecting varieties, and can help soybean...

Information And Results
Project Deliverables

If these objectives are met, then benefits of this research to producers will be:
• Improved recommendations for managing Phytophthora root rot of soybean in Kentucky
• Increased knowledge about Phytophthora sojae race diversity in Kentucky soybean fields
• Increased knowledge of farmers to help them better understand which soybean varieties to plant in fields with a history of Phytophthora root rot.
• Increased knowledge of soybean breeders to better understand which Phytophthora resistance genes (Rps genes) to utilize when developing soybean varieties for Kentucky farmers

Final Project Results

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
