What action can reduce disease severity for Dollar spot?

Fertilizing to avoid nitrogen deficiencies is a crucial action in managing Dollar Spot disease. Dollar Spot is caused by a fungal pathogen that thrives in conditions where grass is weak or nutrient-deficient. By ensuring that the turf has adequate nitrogen, you promote healthy growth, which enhances the grass's ability to withstand infections. A well-nourished lawn can recover more effectively from disease stresses and has a greater resilience against the pathogens that cause Dollar Spot.

Maintaining an appropriate nitrogen level supports the overall vigor of the turf, making it less susceptible to diseases. In contrast, insufficient nitrogen can lead to weakened grass plants, which are more prone to disease infestation, including Dollar Spot. Thus, proper fertilization is a critical cultural practice for disease prevention and management.
