Envu Solutions – Take-all Patch

Take-all patch is an important root disease of all bentgrasses. It is caused by the fungus Gaeumannomyces graminis var avenae. The disease can appear in wet, cold conditions or in warm-hot conditions when plants are experiencing stress. Above-ground injury to bentgrass is due to root infection below ground because the fungus disrupts vascular tissue within the root cortex. Take-all survives on previously infected roots and it can be a recurring problem on infected plants.
