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]
