What is the primary host for the Large Patch disease?

The primary host for the Large Patch disease is indeed warm-season turf grasses. Large Patch is a soil-borne fungal disease caused primarily by the pathogen Rhizoctonia solani, which thrives in warm, humid conditions typically experienced in warm-season grasses. This disease manifests as circular patches of dead grass, particularly during periods of moist weather in spring and fall when temperatures are favorable for pathogen activity.

Warm-season turf grasses, such as Bermuda grass and Zoysia grass, are particularly susceptible to this disease. Their growth patterns and environmental preferences align with the conditions that promote Large Patch development. In contrast, cool-season turf grasses, broadleaf plants, and vegetable crops are generally not affected in the same manner by this specific pathogen, as they are adapted to different environmental conditions, making them less prone to the effects of Large Patch. Understanding this relationship is crucial for effective management and control of the disease in turfgrass landscapes.
