The strategy of using host resistance and environmental management to reduce pest pressure is known as which control approach?

• A. Cultural Control
• B. Core-aerification
• C. Coverage
• D. Diameter

Answer: (A)

Cultural control is the approach that relies on host resistance and environmental management to reduce pest pressure. It focuses on using resistant turf varieties and altering the growing environment to make it harder for pests to establish, survive, and reproduce. In practice, this means selecting grasses bred for pest resistance, and implementing practices that reduce favorable conditions for pests—such as proper mowing height, appropriate irrigation and fertility to avoid lush, susceptible growth, good drainage, soil aeration to reduce compaction, and sanitation to remove pest habitats. These strategies lessen pest problems without relying on chemical controls, addressing how the plant and its environment interact with pests.

The other terms don’t describe this broad, integrated approach. Core-aerification is a specific cultural practice aimed at relieving soil compaction, but it’s just one tool and not the overarching strategy. Coverage and Diameter aren’t pest management concepts relevant to this question.
