Which term describes a moisture-deficit condition that stresses turf?

• A. Drought
• B. Dormancy
• C. Drift
• D. Endophyte

Answer: (A)

When turf is deprived of enough soil moisture, the condition is called drought. Drought describes a moisture deficit that stresses the plant, caused by factors like insufficient rainfall, limited irrigation, or high evaporation, and it can lead to wilting, color loss, and reduced growth. Dormancy is a related but different state where the plant slows or stops growth to survive adverse conditions; drought can trigger dormancy, but the term that describes the moisture deficit itself is drought. The other two terms aren’t about moisture stress: drift is the movement of pesticide droplets by air currents, and endophyte refers to a fungus living inside the plant that can affect health and stress responses but is not the moisture deficit condition itself.
