Anthracnose

Anthracnose is a typical weakness parasite. The disease occurs more frequently between spring and fall. It manifests itself as irregular, sometimes band-like yellowish to reddish-brown patches. The lawn disease anthracnose thus looks very similar to dry damage and is therefore often not recognized as a fungal disease. The lawn becomes patchier. A special feature of the disease is thorn-like black growths on affected blades.

Infestation-promoting factors

  • Nutrient deficiency

  • Long-lasting moisture

  • Too frequent watering

  • Stress (e.g. due to deep cutting, climatic stress, heat, cold, etc.)

  • Soil compaction (waterlogging)

  • High humidity

  • Lawn felt

Preventive measures:

  • Balanced and even nutrient supply

  • Optimize air supply

  • Optimize the irrigation technique, irrigate in the early morning hours to allow the crop to dry quickly

  • Remove dew

  • Reduce thatch

  • Eliminate compaction

  • At very high temperatures above 27°, cool the turf with targeted watering

  • Raise cutting height
