What control method is being used when selecting a blend of tall fescue cultivars with natural pest resistance?

The control method being utilized by selecting a blend of tall fescue cultivars with natural pest resistance is cultural control. This approach emphasizes promoting healthy plant growth and overall turfgrass resilience as a way to manage pests. By choosing specific cultivars known for their resistance to pests, the grass itself is better equipped to withstand pest pressures, reducing the need for chemical interventions or other controls.

Cultural control practices include methods that enhance the growth conditions for plants and discourage pest establishment through strategies such as proper watering, fertilization, and selection of plant varieties adapted to the local environment, which in this case is the focus on cultivars with pest resistance. By employing these practices, turf managers can create a more sustainable and effective pest management system that lessens reliance on pesticides while maintaining turf health.
