Pythium Diseases

A range of fungal Pythium species causing severe damage to cool season (including Annual and Perennial Ryegrass, Browntop Bent, Creeping Bent, Annual Meadow Grass, and more) and warm season turfgrasses (especially Manila Zoysia Grass). Infected turf can be susceptible to the following types of attack:
• Pythium Seed Rot (non-germinating seed rotting away);
• Pythium Blight (most common for new seedlings; also called damping off);
• Pythium Root Rot (wet soil conditions, with roots rotting away).

Pythium is a common cause of damping off and seed rot, so can be particularly prevalent at seeding and germination times.
