A total vegetation killer is a liquid designed to eliminate all of the plants growing in a specific region, including grass, crabgrass, dandelions, and other weeds. This product is primarily used in areas where plants are not supposed to grow, such as sidewalks and driveways. Because of their highly toxic and often acidic nature, individuals need to be careful when choosing a product and handling this liquid.
However, not all total vegetation killers are the same. Some rely on tough chemicals, while more and more manufacturers are trying to switch to more organic ingredients like vinegar to eliminate plants. Others will prevent future growth for up to a year, while some can only promise six months of freedom.
To help you identify the best total vegetation killer available for residential use, this guide takes a look at the ingredients, efficiency, affordability, and longevity. Take a look at these top four picks of 2021. We’re sure you will find one that suits your needs.
What to Know When Picking Vegetation Killer
Vegetation killers are herbicides, or pesticides designed to kill plants. Herbicides come in numerous shapes and sizes and are not effective on all weeds, grasses, and flowers, so it’s important to pay attention to the ingredients of your product of choice. You should also determine how you want to spread the herbicide, and how long you want the vegetation killer to last.
Most herbicides contain the same central ingredients unless they are meant to be organic, in which case chemicals are avoided in favor of vinegar. The most common ingredients are acetic acid, clethodim, fluazifop-p-butyl, glyphosate, metam sodium, pelargonic acid, sethoxydim. Acetic acid is just the more professional name for vinegar, but the others are compounds that are more toxic and targeted towards a variety of different grasses and weeds. When picking your total vegetation killer, it’s best to know what vegetation you are trying to eliminate and what ingredients will work well.
The spreading method refers to how you intend to use the total vegetation killer. The most common way to apply the herbicide is through a spray, but most chemicals are not sold with a sprayer attached. You then need to determine whether or not you want to use a hand sprayer like a bottle, or an actual machine with a wand that allows you to direct the herbicide to targeted areas. When covering a large area, it is recommended to use a larger backpack sprayer for better coverage.
The majority of total vegetation killers claim to last between six and twelve months, but this number varies considerably in practice. Organic killers tend to have the shortest lifespan because they are not as effective at killing the roots, so they need to be applied more often. Most gardeners can expect these to last between three and four months with frequent reapplications.
If you use a toxic chemical killer, the weeds will often be gone for the maximum year before they sprout again. This is because the ingredients seep underneath concrete and similar substances and can attack the roots directly. In many cases, vegetation will be gone for good. For this reason, a chemical total vegetation killer tends to be the most effective choice, but not the best for the environment.
In terms of longevity, you also want to consider when the product will become rain-ready. When a vegetation killer becomes rain ready, it means the formula won’t be washed away from exposure to moisture. Products vary tremendously, with some being rain-ready in as little as half an hour, while others can take up to 48 hours to be fully integrated into the roots of weeds and brush. Always read the instructions before applying.
