Which practice helps prevent disease by selecting appropriate turf species?

• A. Improve airflow and light availability
• B. Select appropriate turf species
• C. Provide appropriate fertility
• D. Mow very short

Answer: (B)

Choosing an appropriate turf species is the best way to prevent disease because it directly lowers the plant’s vulnerability by matching the species to the site’s climate, soil, drainage, and light conditions—and often to local pathogens. When the turf is well-suited to the environment, it grows with less stress and can resist or tolerate diseases better, making outbreaks much less likely. Other practices like improving airflow and light reduce disease risk by altering conditions, balanced fertility supports healthy growth, and mowing at a proper height reduces stress, but none addresses the plant’s intrinsic susceptibility as effectively as selecting a species that fits the site.
