Quackgrass - Is Q4 effective at killing quackgrass?

Are there any chemicals available through your company that can eradicate quackgrass?

Answer:

Quackgrass is a grassy weed, so you need a product labeled for grassy weeds.  Certainty is our most popular product for quackgrass and other grassy weeds.
