Pythium Leaf Blight appears suddenly during hot, humid weather. Infected leaves become light tan to brown, shriveled and matted when dry. When humidity remains high the collapsed leaves become matted and covered with a fluffy white mass of fungal mycelium.
Pythium Leaf Blight
- General Information
Conditions Favouring Disease
Hot days (30-35 degrees C), humid or rainy weather when night temperatures are warm. Relative humidity exceeding 90% for at least 14 hours and a minimum temperature not falling below 20 degrees C. Lush, dense grass growing under high nitrogen fertility is especially susceptible to attack.
Management Tips
Maintain good surface and subsurface drainage, avoid over-watering new plantings and avoid watering late in the day. Remove excessive thatch, increase air circulation to speed up the drying process of the turf. Water infrequently and deeply.
