Pythium species management controls and recommendations

Serata (0.6 fl oz per 1,000 square feet)2. Resilia (4 fl oz per 1,000 square feet)3. Segway (0.45 fl oz per 1,000 square feet)
Serata should be applied for preventative control every 21 to 28 days in the fall and spring when mean daily soil temperatures are between 50°F and 75°F. Curative applications should be made every 14 to 28 days based on the appearance of symptoms.
In recent trials, we have not observed significant differences among QoI fungicides when used alone for Pythium root dysfunction. Regardless of which fungicide is applied, effective curative control also requires increased mowing heights and nitrogen inputs to relieve stress and allow the affected plants to heal.
