Cet herbicide s’est révélé très efficace pour éliminer les mauvaises herbes dans ma cour arrière . Son action rapide permet de constater les premiers résultats en quelques jours seulement. De plus, il offre une bonne rémanence, limitant la repousse à court terme. Facile à appliquer, il constitue une solution fiable pour le désherbage ciblé.

    I got this product my lawn to kill the creeping charlie I read the reviews and I was expecting a miracle in 2-3 days it's not as fast as they said it was there were reviews that said it was no good so I was not sure what to do so I ordered a bottle and sprayed the lawn checked the 2nd day no differance so I thought the people that said it was no good were right.after about 2 weeks I noticed there was less of it so I thought I would order more and spray it again and I think about week 3 I seen all the other weeds were dieing so I never bothered to spray again and my creeping charlie is almost gone it's not fast but it works really well I will spray again in October because the internet says that is the best time to because the roots take it down into the plant for the winter and don't come back up also going to spray some of the 3 properties around me because I see it on their property I don't want it back
    I THINK THE PEOPLE THAT GAVE IT A BAD REVIEW DID NOT WAIT LONG ENOUGH
    Ok I am back it's Dec. 09/24 I sprayed this product on my lawn back about July checked it every day and it was slowly killing the creeping charlie then I stopped checking it every day and forgot about I checked it about a week ago and the bonus is I can not find any weeds I sprayed my lawn the second time in Oct.and there was still some left so I thought with the second spray I would get it I checked it today and it's gone and then I started looking at my lawn and I noticed all my other weeds were gone it took all my weeds I have a weed free lawn this stuff is great it's slow and steady after I sprayed it I had an awful lot of black spots in the yard and it looked bad but that was just it killing the creeping charlie I now only have a few the other way to get rid of this p stuff is to cover your c/c with a tarp let it sit for 2 weeks then dig it up put down new top soil and replant! Ain't going to happen I would have had to cover my whole lawn.this method is way easier it's spray it and forget it I wasted a lot of time checking on it it was like a watched pot never boils. THIS PRODUCT IS GREAT JUST PUT IT ON AND LEAVE IT ALONE DOT RUSH IT IT TAKES TIME I AM THANKFUL I DO NOT HAVE TO DIG UP MY LAWN I WOULD GIVE IT 10 OUT OF 10.ITS GREAT

    Works great and the lawns are the envy of the neighborhood.

    .... because it's a concentrate you can mix what strength you like and
    deide how you spray. In our case since using Ortho last year we only spot spray rather
    than whole lawn as suggested by a lawn spraying service.

    Very good product. Since it is selective, it does not burn the lawn. Since I had almost more weeds than grass, I doubled the dose and everything died in 4-5 days. And the few slabs dotted with grass are always green. Wait until it doesn't rain for about 2 days before applying it. The product arrived perfectly.
    I recommend

    Reviewed in Canada on September 1, 2019

    I have been using this product for a few months now so it’s time for a review. Overall, this product is slightly above average. It does not kill all weeds and that’s it’s downfall.

    After 4 applications, it has clear out 95% of my ground ivy. VERY IMPRESSED. It does a good job killing clover too but for the best result for clover removal, I found it works best if you add some dish soap to ur sprayer tank so it sticks to the clover. With no dish soap the spray rolls off the leaves of the clover and is not as effective (needs multiple applications). The ground ivy was kills off with ease with or without dish soap, and it didn’t kill the grass !

    After some testing I found 6-8ml / liter to work the best. 9-10ml / liter and it killed about 40% of the grass. The 60% of the grass that remained was still in good condition and I suspect it to bounce back, but not worth the higher mixture in the long run.

    After an application you really need to give it time. I noticed hardlt any results for 2 days but I seen weed die off predominantly from day 3 for up to 10 days. I sprayed my applications once every 2 ish weeks.

    Dandelions it will kill, in time, but some times they regrow before fully dying. wild strawberry it was not very effective at all, along with a few other weeds I don’t know the name of.

    It destroys ground ivy, kills off clover, and is mediocre with dandelion removal. I will continue to use this product next year. I have over half the bottle left over.

    P.S I use a respirator while applying and shower when I’m done. That 2-4-D chemical is nasty nasty. I kept my indoor/outdoor cats INSIDE for 3 days after spraying to be safe. 24D was used in chemical orange in the Korean war so. It’s no joke LOL.
