What benefit do beneficial fungi, such as endophytes, provide to grass plants?

Beneficial fungi, particularly endophytes, play a vital role in grass health by producing alkaloids that enhance pest resistance. These alkaloids can deter herbivores and insects from feeding on the grass, thereby reducing damage and improving the overall survivability and vigor of the turf. This symbiotic relationship allows grass plants to thrive even in conditions that may be more challenging due to pest pressures.

While there are other benefits associated with fungi in general, such as decomposing organic matter or promoting water uptake, the specific function of endophytes in grass plants is primarily linked to their role in pest resistance through the production of these protective compounds. This not only aids in defense against pests but can also lead to healthier and more resilient turfgrass ecosystems.
