Which statement best describes SpeedZone?

• A. SpeedZone provides broadleaf weed control and performs well under cool conditions.
• B. It only controls grasses.
• C. It is ineffective in cool weather.
• D. It is a preemergent herbicide.

Answer: (A)

SpeedZone is a postemergence turf herbicide formulated to control broadleaf weeds and to perform well in cooler temperatures. It combines carfentrazone-ethyl with 2,4-D, MCPP, and dicamba, which gives rapid knockdown and broad-spectrum broadleaf control. This cool-weather effectiveness is particularly useful because many broadleaf weeds are actively growing in cool conditions, and some products lose activity when temperatures are lower. It is not a preemergent, and its primary action targets broadleaf weeds rather than grasses. So the best description is that it provides broadleaf weed control and performs well under cool conditions.
