The weedkiller is easy to use but some of the crabgrass needs some more. You can smell it for days!

Crab grass has been the scourge of my lawn for years. I tried keeping the lawn super short and pulling it out, but nothing short of tearing up whole sections of lawn and reseeding seemed to work, until now. This does kill, or at least badly yellow, crab grass on a first application. It’s not systemic so it looks like it will need a few applications to get it all, but I can’t tell you how much I enjoy watching this weed die off. A few words of caution, the instructions are in imperial old school measures, so it’s easy to miscalculate exactly how much weed killer to add to a quart per furlong but over dosing doesn’t seem to harm normal grass too much. The delivery is also impossibly long. After a couple of weeks I checked what was happening and the eta on a new purchase was quicker than my old order.

Only product that works for me killing my crabgrass in my lawn Im the uk

Appallingly slow and indifferent delivery of a dismal product which is being returned

I did not see the results until about 6 weeks after application and almost all the crabgrass in my lawn is dead

Not sure it works on UK crabgrass, but more importantly the chemicals in it are not UK or EU approved it seems.

no impact as yet on the crabgrass in our lawn two weeks after correct application.

My lawn was invaded by crabgrass this past spring. I applied this once and within a couple of weeks, no more crabgrass.

Works as advertised

As much as I like to eschew extreme ratings of either 1 or 5 stars (in my experience, a product is rarely the best or worst thing imaginable), I cannot, in clear conscience rate this BioAdvance product any higher than the lowest end of the scale. On the very top of the list of safe grasses on which to use this product is Bermuda. After using this grassy weed killer, I have a series of brown dead spots in my Bermuda lawn with crabgrass thriving happily in the middle (see attached photo). The same can be said for the zoysia in my backyard. I must admit, however, that the headline of this review is a little misleading. The Bio-Advanced All-in-one Lawn Weed and Crabgrass killer fails to kill sedge grass as well as crabgrass. So, the 2 grassy weeds I would most like to get rid of seem to react to this product as if it were a tasty meal. While at the same time my true lawn grasses are dying anywhere it was applied.

Works fantastic on crabgrass!

It seems to slow down the crabgrass, even without using MSO oil. I’m thinking it might be more effective with it—planning to give it another shot next spring.
