Which statement about Barricade (prodiamine) is correct?

• A. Season-long control is possible with a single application.
• B. Requires annual reapplication.
• C. Only controls crabgrass.
• D. Only for zoysia lawns.

Answer: (A)

Barricade is a preemergent herbicide that creates a soil barrier to prevent germination of many annual grasses, especially crabgrass. When applied at the right rate and timing and watered in, its residual activity can last through a significant portion of the growing season, often providing season-long control from a single application. It isn’t limited to crabgrass, and it isn’t restricted to zoysia lawns; it’s labeled for use on multiple turfgrasses and targets various annual grassy weeds. So, a properly timed single application can indeed offer season-long control, making it the best choice.
