Bare Spot Monobor-Chlorate 

Unlike many herbicides that must be applied repeatedly all season long, one easy application of Monobor-Chlorate pellets in the Spring will give you 6-9 months of hassle free weed control.


Monobor-Chlorate pellets can be applied by hand directly from the container or with any spreader suitable for granular fertilizers. Because the pellets are visible, this eliminates "skips" and "misses". There is no guesswork involved.


Monobor-Chlorate is a great product for controlling weeds and grasses in and around the following areas: Gravel driveways, sidewalks, walkways, fence lines, out builds & sheds.

Fast Results: Within days after application and moisture (rain or sprinkling), the foliage and root system of weeds and grasses die. A residual barrier remains in the upper soil for 6-9 months to control later-germinating weeds.

Is this effective against Japanese Knotweed? Or would you recommend something else?
Guy M on Mar 20, 2018
BEST ANSWER: Barespot will kill everything and meant to be used in an area that you want no vegetation to grow. Herbicides with an active ingredient of glyphosate (Rodeo, Aquamaster, Gly Star, Round-up among
others), triclopyr (Garlon 3a and many “shrub-killers”), 2,4-D, picloram (Tordon) and Imazapyr
(Arsenal) have shown to be variably effective in controlling knotweed either separately or in combinations.

One Time Total Control
I have been using this stuff for years and love it. It is the only product I have found that can be applied once and not only kills pre-existing weeds, but prevents recurrence for almost a year. I try to apply it to our gravel driveways and parking areas in March to have it last into winter. The pellets are large enough to see where you have applied it. It is important to water it in (or you will track it into unwanted areas). I have even put it down during rain with no issues.

Driveway treatment
I put this on my gravel driveway after trying Round-up without success. This stuff completely eliminated the weeds for over a year!
