Which practice is likely to reduce the risk of pests in a turfgrass environment?

Overseeding with resistant species is an effective practice for reducing the risk of pests in a turfgrass environment. By introducing turfgrass varieties that have been developed or selected for their natural resistance to pests and diseases, the overall health of the lawn is enhanced. These resistant species can better withstand pest pressures and stresses, resulting in a more robust turf that is less susceptible to infestations, thereby minimizing the need for chemical pest control measures.

Implementing this practice not only helps in managing existing pest problems but can also be a proactive strategy for future pest prevention. Resistant species often have traits that enable them to thrive despite environmental challenges, making them a strategic choice for sustainable turf management. In contrast, decreasing irrigation frequency does not directly target pest populations, neglecting soil health can lead to a weak turf that is more vulnerable to pests, and applying less fertilizer could inadvertently weaken grass health and resilience.
