What does "Healthy turfgrass is tolerant turfgrass" signify?

Healthy turfgrass is often characterized by its ability to withstand pest issues without experiencing significant damage, which is what makes the understanding of tolerance critical for effective pest management. When a turfgrass is tolerant, it suggests that the grass possesses the resilience to endure certain pest pressures, maintaining its vitality and function even when faced with infestations. This cultural approach helps in reducing the need for chemical interventions, thereby promoting environmental sustainability and reducing costs associated with pest control measures.

The other options do not align with the principle of tolerance. For example, stating that it requires constant management to survive implies a dependence on continual intervention rather than natural resilience. A turfgrass that cannot recover from pest problems points to a lack of tolerance, contradicting the definition. Lastly, while thriving in poor environmental conditions can suggest hardiness, it does not specifically relate to pest tolerance, which is focused more on dealing with active pest pressures rather than overall environmental adaptability.
