The Roundup Dual Action 365 Weed & Grass Killer Plus 12 Month Preventer Concentrate is designed to provide long-lasting weed and grass control. Its key strength lies in its residual effect, as it claims to kill and prevent weeds for up to 12 months. This makes it a powerful option for those looking for long-term solutions in non-lawn areas like driveways, sidewalks, patios, and under decks.

The application method is straightforward; the concentrate can be mixed and applied with a tank sprayer, covering up to 1,600 square feet with each 32 fl. oz. bottle, which is quite efficient for large areas. Another highlight is its rainfastness, as it becomes rainproof in just 30 minutes, ensuring it's effective even if it rains shortly after application.

The product is effective and targets many tough weeds, though it may not be selective and can harm desirable plants if not applied carefully. It is a potent chemical herbicide, which may not be suitable for eco-conscious users or those with pets and children. The Roundup Dual Action 365 is a robust and long-lasting solution for weed control in non-lawn areas, with quick action and easy application but should be used with caution regarding environmental and safety concerns.

The RM43 Concentrated Extended Control Weed Killer is a potent herbicide aimed at serious weed control. Its active ingredient, glyphosate, is well-known for its effectiveness in eliminating tough weeds and vegetation. One of its significant advantages is its long residual effect, offering up to one year of weed control. This makes it suitable for users looking for extended vegetation management, particularly in larger areas, given its coverage of 17,297 square feet per container.

The application method is straightforward as it mixes with water and applies using a sprayer, making it user-friendly for those who prefer easy application processes. Additionally, its rainfastness ensures that it remains effective even after rainfall, which is crucial for reliable weed control in varying weather conditions. However, there are some drawbacks to consider. The environmental impact of glyphosate is a concern, as it can affect non-target plants and potentially harm surrounding ecosystems. Users should also handle the product with care to avoid unintended damage to desirable plants.

Another point to note is the weight of the container at 9.4 pounds, which might be cumbersome for some users. The RM43 product has achieved strong customer reviews, boasting a 4.6-star rating from over 6,600 reviews, indicating general satisfaction among users. In summary, this weed killer is highly effective and long-lasting but requires careful handling due to its environmental effects.

The Ortho GroundClear Year Long Vegetation Killer1 Concentrate is designed for effective weed and grass control, boasting a strong residual effect that prevents regrowth for up to one year. The active ingredient, Imazapyr, is known for its potency in killing unwanted vegetation down to the root. This product is particularly suitable for use on driveways, sidewalks, gravel areas, parking areas, rock and desert landscapes, under decks, and along fences, making it versatile for various outdoor spaces.

The application method involves mixing 24 fl. oz. of concentrate per gallon of water and using a tank hose sprayer, which may require careful handling to ensure safety and effectiveness. One gallon of concentrate can cover up to 1,600 sq. ft., offering substantial coverage for larger areas. Rainfastness is a critical factor for herbicides, and this product starts working immediately, which should minimize concerns about rain washing it away soon after application. However, users should still follow instructions closely to achieve optimal results.

In terms of environmental impact, products like these need to be used with caution to avoid unintended damage to surrounding vegetation and ecosystems. This herbicide is best suited for those looking for a strong, long-lasting solution to control persistent weeds and grasses in specific outdoor areas.
