For Weed control along fencelines, roadsides and troublesome areas, we typically utilize RM43. ​RM43 is a powerful "scorched earth" herbicide designed for total vegetation control in non-crop areas. It contains 43% glyphosate and a residual ground sterilizer. It is highly effective for fence lines, gravel driveways, and barnyards, but requires extreme caution to avoid damaging desirable plants. [1, 2, 3, 4]

Pros

• Long-Lasting Control: It acts as both a post-emergent (kills existing plants) and pre-emergent (prevents new seeds from sprouting), keeping areas weed-free for up to 12 months. [1, 2]

• Handles Tough Weeds: Highly effective on over 150 tough-to-kill species, including poison ivy, kudzu, and wild blackberry vines. [1, 2]

• Concentrated Value: A single gallon of concentrate makes up to roughly 17 gallons of mixed spray for full-strength total vegetation control. [1]

• Rainfast: It typically becomes rainfast within two hours of proper application. [1]

Cons

• Total Vegetation Kill: It is indiscriminate and will kill any grass, shrub, or tree it touches, making it entirely unsuitable for lawns, gardens, or flowerbeds. [1, 2]

• Root Absorption Risk: Because it sterilizes the soil, it can leach or drift via heavy runoff. Spraying it near the root zones of desirable trees (like oaks) can severely injure or kill them. [1, 2, 3]

• Delayed Replanting: You cannot plant anything (like vegetables or grass) in the treated soil for 8 to 12 months. [1]

• Upfront Cost: While concentrated, the initial price tag can be high compared to standard, less-persistent herbicides. [1, 2, 3]

Could you tell me what specific area or plants you are trying to clear, as well as how close you are to other trees or gardens? This can help determine if RM43 is the right fit or if a milder option is better.
