Grass Out Max is a non selective grass killer, meaning it will kill your KGB as well. A better option would be use Q4 for everything but the quackgrass and the poa annua. Unfortunately there is not an herbicide that would kill the quackgrass nor poa annua without damage cool season turf, such as Kentucky Bluegrass. If only a small area of the lawn is affected by the outbreak, spray only the affected area with RoundUp Quick Pro. If the problem amounts to no more than a few spears of quackgrass in an area of your lawn, paint the individual spears with diluted RoundUp QuickPro. Becareful to avoid getting the product on desirable grass. 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 Roundup. 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 the replanting.
We do not recommend storing Grass Out Max or any other insecticide where there are extreme temperatures. Store products in cool, dry place for the most effective results. If it hs been frozen, we suggest getting fresh product.
? Grass Out Max? is specifically designed to kill any and all grasses it is sprayed on and ONLY kill grasses. This would not be a product you would want to use over a lawn and instead you would want to go with a product that is selective in either a pre or post emergent form. Because poa annua and and fescue are so closely related, there are few products that will kill the poa annua without also harming the fescue. The only one we are currently aware of is called Prograss. Your other options would be to either spot-treat with a Roundup-type? product and then reseed with the fescue in those areas, or you can use a preemergent like Prodiamine 65 WDG in the fall to prevent the poa from growing in the first place.
