Pythium Blight Problem • Primarily affects cool season grasses. • Common in hot summer weather (29-35°C) with little air movement and high relative humidity. Can occur at lower temperatures (20°C) when other environmental factors are suitable. • Water logged, poorly drained turf is particularly susceptible. • In warmer climates can also attack Bermuda grasses. • Lush over fertilized turf susceptible to attack. • The disease spreads rapidly and can destroy large areas overnight. • First appears as rough circular patches from a few centimetres up to 15cm in diameter. • Grass plants within affected area look dark, slimy, greasy and often mat together. • May be covered in white mycelium. • The infection can look streaked as it follows channels of natural drainage and paths of mowing equipment.
