Endophytes play a crucial role in the health and resilience of turfgrass by providing a built-in defense against certain insects and environmental stresses. These naturally occurring fungi live within the plant tissues and can produce chemical compounds that deter herbivorous insects, reducing damage and minimizing the need for chemical pest management. Additionally, endophytes can help turfgrass tolerate stressors such as drought, heat, and disease, enhancing the overall vigor and sustainability of the grass. This symbiotic relationship allows the turf to maintain a stronger defense system and improves its capacity to thrive in various conditions, contributing to healthier lawns and landscapes. Other options may address important aspects of grass health or soil quality, but they do not specifically relate to the role that endophytes play in providing natural defenses to the grass.
