Product Q&A

Answer:

Crossbow Herbicide is labeled to be used on Rangeland, Grass Pastures, Fence rows, roadsides and non-crop areas. It is not labeled to be used on St. Augustine grass. It will likely kill it. You can use Speedzone Southern for Dollarweed in St. Augustine grass. According to the product label of Speedzone Southern: The turf tolerance to this product may vary and temporary turf grass yellowing may occur on St Augustine. Do not apply Speedzone Southern to Floratam, Bitterblue or other improved species of St Augustine. Do not broadcast or spot spray St Augustine during the fall to winter transition or if temperatures are expected to fall below 40F within 10 days of the application.
