I have been using Weed B Gon Max for a few years to get rid of weeds in my lawn but a couple years ago I noticed a product called Weed B Gon Max Plus Crabgrass and bought it to get rid of the stubborn crabgrass growing in my lawn.
Available applicators: This product comes in several applicator types including one that you can use your hose to spray it all over your lawn. You can also buy it in a concentrate that you can mix with water and use in your own sprayer. I try to use weed killers sparingly so I just buy the small 24 oz spray bottle of ready mixed product. You can get the same product in a larger sprayer but I still prefer the small bottles and I do not use that much to warrant the larger size. The other thing to keep in mind is that these chemicals can lose their effectiveness over time so it’s best to buy the right size and application for your needs. If this sits around in your garage for a year it may not be as effective when you go to use it next season. While it states that it is effective for up to three years I find it works best when used during the same season as when I buy it.
Sizes Available in the ready mixed: 24 oz Bottle with sprayer, .5 gal Bottle with sprayer, 1 gal Bottle with sprayer, and 1.33 gal Bottle with Pull-N-Spray applicator.
The 24oz Spray Bottle Applicator: The weed killer comes in a 24oz green plastic Spray bottle. The top screws on and is orange in color with a white twist nozzle that you can set on two different sprays. One sprays more broad and the other is a narrow spray. The other two settings close the nozzle so you can not spray. There is a label that gives you all the information you may want about this product and there is a peel off label on the back that folds out with even more information.
Active ingredients: The normal weed be gon max has Dicamba, which kills a variety of weeds. This product also adds something called Quinclorac. I will admit that I have no clue what these chemicals are but I use caution to not get them on my hands or breathe them in.
How I use it
One thing to remember about this product is that when you spray it you will not go out the next day and find all the weeds dead. It takes time for them to die and disappear from your lawn. It is important to give some time between spraying and mowing as the chemicals will work slowly to get from the leaves to the roots of the plant and kill it over the period of a couple weeks. I would spray your lawn or weeds a couple days after mowing and wait about 5 more days before mowing. If after two weeks you still see the weeds or new ones have appeared spray again in the same way. You have to have a little patience and I think I have seen reviews of this product where people complain that it does not work immediately. The truth is that if you want to use a product that is safe for your lawn but will kill weeds it takes time.
For Crabgrass, spray as soon as you see the little things emerging. If you wait until you have a full blown Crabgrass plant it can take longer to kill it and also the weed is so huge it has done some damage to your lawn at that point. Crabgrass starts in July so that is the time to start looking for it. If I notice a larger plant I will just pull those and spray the smaller ones. Since I spot spray I will walk the yard about once a week a couple days after mowing and spot spray any plants that I see. If you start early and are vigilant you will prevent crabgrass from taking over your lawn.
If you have more than a few plants you may want to get a larger size or the sprayer that attaches to your hose to do the whole thing. In that case you would follow the instructions for that product which is slightly different from the ready mixed as used for spot spraying.
When I spray I coat all offender plants thoroughly. the spray is easy to use and you can see what you have already sprayed because it looks slightly foamy at first. This disappears quickly as it dries so make sure to go through your lawn from one side to the other so you will not end up wasting product by double spraying.
According to the instructions this will dry in one hour so if it rains an hour after you spray it should have sufficiently soaked in. I have found that in reality I get the best results if I have 24hrs between spraying and rain or watering my lawn.
How well it works to kill weeds
I think that Weed B Gon Max plus Crabgrass Control works great. As I stated before you have to have patience and give it a few weeks to work completely but if you spray this when weeds first appear and then reapply once or twice more it does a great job at not letting weeds and crabgrass take over your lawn. It is not a complete miracle and takes a little bit of vigilance on your part. If you want something to immediately kill the weed you will need to use something else but then you risk damaging your lawn.
Does it harm Grass Lawns?
I have never noticed any damage to my lawn from using this product This is the primary reason that I keep using this product.
Final thoughts and Rating
I have to give this product 5 stars because considering how safe and gentle it is on my lawn it really does get rid of the weeds and crabgrass over time. I am fine with it taking a few weeks to work because I know that it will not harm the rest of my lawn. Also weeds will shrivel up and die over time without making my lawn look terrible in the process. The key is to get the weeds when they are small and easier to kill. Your success and satisfaction of this product depends greatly on your understanding of how the product is designed to work.
