What management technique can reduce the incidence of turf diseases?

Regular aeration practices are effective in reducing the incidence of turf diseases because they enhance soil health and improve turfgrass resilience. Aeration involves perforating the soil with holes to alleviate compaction, increase oxygen levels in the root zone, and improve water infiltration and nutrient uptake. By fostering better root development and overall turf vitality, aeration limits the conditions that are often conducive to disease development, such as excess moisture and poor drainage.

In contrast, practices like overwatering and excessive nitrogen fertilization can create ideal environments for various turf diseases by promoting lush, dense grass that is more susceptible to pathogens. Additionally, infrequent mowing can lead to longer grass blades that may hold moisture longer, further increasing disease risk. Regular aeration is therefore a proactive approach to maintaining healthy turf that minimizes the potential for disease outbreaks.
