Fertilome Over the Top II Grass Killer

It is very important to use a surfactant or spreader/sticker with this product to maximize its effectiveness.

Fertilome Over the Top II Weed Killer is a systemic selective broad spectrum post-emergent herbicide that can be sprayed over desired plants listed on product label to control annual and perennial grasses. Fertilome Over the Top II can be used on vegetables, gardens, trees, shrubs, ornamentals and ground covers and stops growth of weed grasses within 2 days.

This product is not to be used to control grasses in lawns or turf.




Over the Top II Grass Killer is a selective systemic grass killer to eliminate existing weedy grasses growing in and around plant beds, landscapes, and individual shrubs and trees. It can be used through a hose-end sprayer according to the directions of the sprayer used or through a tank-type sprayer. Over the Top II can also be used around listed fruit and vegetable areas, see label, wherever listed weedy grasses occur. Use only tank-type sprayer.

Over the Top II kills most annual and hard-to-kill perennial grasses up to 1 foot high, including the examples listed below in one or two applications. Younger, actively growing seedling weeds are more easily killed than older, mature, well-established grassy weeds which may require a repeat application for control. Adding oil concentrate may help control of grassy weeds.

  • Barnyardgrass
  • Bermudagrass
  • Broadleaf Signalgrass
  • Crabgrass - Large, Smooth
  • Fall Panicum
  • Foxtails - Giant, Green, Yellow
  • Goosegrass
  • Johnsongrass - Seedling, Rhizome
  • Junglerice
  • Lovegrass
  • Orchardgrass - Seedling
  • Quackgrass
  • Tall Fescue - Seedling
  • Texas Panicum
  • Shattercane/Wildcane
  • Wild Proso Millet
  • Wirestem Muhly
  • Witchgrass
  • Wooly Cupgrass

    5 of 5 stars  Great Product!
    By Tim in Kansas on 05/26/2011
    Verified Purchase

    This Over the Top II is a great product that works very well as long as you follow the instructions to the letter. You must use an oil additive with it, such as Spreader Sticker, because all grass, even crab grass, has a waxy coating that causes water and chemicals to bead up and run off, thus greatly reducing the effectiveness of any chemical. I used Spreader Sticker with the Over the Top II and all of the crab grass that I sprayed had stopped growing after 24 hours and was completely dead within 10 days. Of course I sprayed the crab grass when it was still relatively small. It also worked, with the same result, on the Bermuda grass I sprayed.

    Have been looking for something to get rid of the Bermudia grass in my lawn without killing my Cenipede grass. Tried this product and it eliminated the problem. It did so well that some of my neighbors saw what happened to my lawn and now they are using this product as well.

    5 of 5 stars  It Works!
    By Bill in Fairfield, CA on 07/07/2012
    Verified Purchase

    I am currently using this product to kill the grass that is growing in my Strawberry Groundcover. It looks like it is working. I was dubious, since I could not find an Ortho or Monsanto product that claimed to kill grass but leave groundcover unharmed. However, I am also incredibly lazy, so I decided to try it. It works.

    3 of 5 stars  Not sure if it works.
    By Lydia in Texas on 09/26/2016

    It has been almost 3 weeks since I sprayed this. It seems like the weeds have stopped growing but they are not dead. I used this with the spreader sticker on newly planted Asian jasmine, which survived the spray. Was hoping the weeds would be dead by now. I previously pulled weeds in one area and sprayed there afterward. There are no weeds growing there now.

    5 of 5 stars  Great Stuff!
    By Owen in Raleigh, NC on 08/18/2016

    Bought to eradicate extensive amounts of crabgrass and stilt grass that had invaded my Tall Fescue lawn (or what was left of the lawn). Sprayed this mixed with Spreader-Sticker in a pump sprayer before the crabgrass went to seed. Stopped all growth (haven't had to mow at all) and starting turning brown within 3 days. After a week, every crabgrass was brown or well on it's way. Lawn looks like heck (no more green) but the lack of rain hasn't helped either. Next up is aeration and overseed. Raleigh NC

    By Seth in Hamlet on 08/05/2016

    I bought this to control Bermuda in my centipede lawn. It has been two weeks from application day and the Bermuda has been knocked way back. It may take 1 to 2 applications to achieve total control but my centipede is unharmed. That being said I am pleased with the product.

QRecommended Weed Killer for flower bed and around tree/shrubs?
I have a lot weeds in my shrub bed and I would like to use something that would kill the weeds but not the trees and shrubs.

AWe do carry a few products that can be used in flower beds and around trees and shrubs. Fertilome Over The Top Grass Killer (post emergent), Hi Yield Weed and Grass Stopper (pre-emergent) and Dimension 2EW (pre-emergent) and several others. We recommend you identify the weeds you are having issues with before selecting a product as most products only work for the weeds they list on their product labels. You can contact your local cooperative extension office and speak to the master gardener on staff if you need help identifying weeds. The master gardener can also tell you what type of herbicide will work best in your region right now (pre or post emergent) and won't damage your ornamental plants. Always be sure to read the product label of the product you select before purchasing to make sure the weeds you are trying to eliminate are listed and the ornamental plants you have are listed as a species that is tolerant to the herbicide. All product labels (for the products we carry) can be found on the individual product pages under the pictures of the product.

QWhat is the oil concentrate that is mentioned in mixing instructions?

AThe oil concentrate is a surfactant.  Most herbicides should always be mixed with a non-ionic surfactant.  This is because since grass and plants have waxy coatings on them, most herbicides that are mixed with water do not stick very well to this waxy coating.  Adding a surfactant breaks down the wax on the grass or ornamentals and allows the solution to stick and work much better.  We sell the non-ionic surfactant on our website and it is also linked on the Fertilome Over-The-Top page.
