Product Q&A

Answer:

Avenger Weed Killer Concentrate can kill quackgrass and just about anything else it is applied to. Be careful to avoid getting the product on desirable vegetation. If most of the lawn has been affected by quackgrass, the only sure fire way to get rid of it is to spray the entire lawn with Avenger. Spray when the lawn is growing actively, preferably in the spring. The treatment will kill the lawn grass as well as the quackgrass. After about two weeks, you may begin replanting.
