Mode of Action
Application Method

Most important from
7129 reviews

Type of Herbicide
Spectracide Weed And Grass Killer Concentrate is an effective and less-costly approach to controlling weed growth on patios, walkways, and driveways.
Mode of Action
This product works great as long as you mix the concentration with the correct amount of water, effectively killing whatever plant, weed, or grass it is sprayed on.
Application Method
For stubborn weeds, using a more concentrated mix ensures thorough elimination even during the rainy season.

The Spectracide Weed And Grass Killer Concentrate is designed for use on patios, walkways, and driveways. It's a fast-acting herbicide, with visible results in as little as 3 hours, making it convenient for quick garden projects. One of its key strengths is that it becomes rainfast just 15 minutes after application, ensuring that rain or watering won't diminish its effectiveness.

This product is a concentrate, requiring mixing and application with a tank sprayer to cover target vegetation thoroughly. It effectively kills weeds and grasses down to the root, ensuring long-term results. Additionally, it is a non-selective broad-spectrum herbicide, meaning it will kill almost any plant it is applied to, which is suitable for areas where complete weed removal is needed but may not be ideal for areas with desirable plants that could be accidentally affected.

Its non-selective nature requires careful application to avoid damaging nearby plants. Also, it is worth noting the environmental impact, as the product may affect soil health and nearby water sources if not used responsibly. This herbicide is a powerful and quick solution for clearing unwanted weeds and grasses in specific areas, but it requires careful use to avoid harming other plants and the environment.

Ortho GroundClear Year Long Vegetation Killer2 Concentrate, Kills and Prevents Weeds Up to 12 Months, 1 gal.

Rating

Residual Activity
Weed Spectrum
Application Method

Most important from
5005 reviews

Residual Activity
Delivers powerful, long-lasting weed control that keeps areas clear for up to a year.
Weed Spectrum
Effectively kills all unwanted vegetation down to the root, preventing quick regrowth.
Application Method
Has a strong odor during application, which some may find unpleasant.

Ortho GroundClear Year Long Vegetation Killer2 is a liquid herbicide designed for areas where you want to prevent any plant growth for up to a year, such as driveways, sidewalks, and gravel areas. It works by killing existing weeds and grasses down to the root, which helps stop them from coming back quickly. You apply it by mixing the concentrate with water and using a hose sprayer, making it easy to cover up to 300 square feet per gallon of mixed solution.

A key advantage of this product is its long-lasting effect—once applied, new weeds typically do not appear for about 12 months, making it a convenient low-maintenance solution for tough areas. The herbicide acts quickly, providing visible results soon after application. However, since it prevents all plant growth, it should not be used near plants or lawns you want to keep. Additionally, the coverage area per gallon is limited, so treating larger spaces might require multiple purchases.

While the product is effective, users should be cautious about its environmental impact because it eliminates all vegetation, and repeated use could negatively affect soil health. This herbicide is a strong choice for powerful, long-lasting weed control on hard surfaces where no plants are desired, but it is not appropriate for garden beds or areas where some greenery should be maintained.

Buying Guide for the Best Herbicides

Choosing the right herbicide can be crucial for maintaining a healthy and productive garden, lawn, or agricultural field. Herbicides are chemicals used to control unwanted plants, commonly known as weeds. The right herbicide will help you manage weeds effectively without harming your desired plants. To make an informed decision, you need to understand the key specifications and how they align with your specific needs. Here are the key specs to consider when selecting a herbicide:
Type of HerbicideHerbicides can be classified into two main types: selective and non-selective. Selective herbicides target specific types of weeds while leaving other plants unharmed, making them ideal for lawns and gardens where you want to protect certain plants. Non-selective herbicides kill all plants they come into contact with, which is useful for clearing areas completely. Choose selective herbicides if you need to protect certain plants, and non-selective if you need to clear an area entirely.
Mode of ActionThe mode of action refers to how the herbicide affects the plant. Systemic herbicides are absorbed by the plant and move throughout its tissues, killing it from the inside out. Contact herbicides, on the other hand, kill only the parts of the plant they touch. Systemic herbicides are effective for perennial weeds with deep root systems, while contact herbicides are suitable for annual weeds and quick results. Consider the type of weeds you are dealing with and their growth patterns when choosing the mode of action.
Application MethodHerbicides can be applied in various ways, including sprays, granules, and liquids. Sprays are easy to apply and can cover large areas quickly, making them ideal for lawns and fields. Granules are spread over the soil and are activated by water, which can be useful for pre-emergent weed control. Liquids can be mixed with water and applied directly to the soil or plants. Choose the application method that best fits your area size, weed type, and convenience.
Residual ActivityResidual activity refers to how long the herbicide remains active in the soil after application. Some herbicides break down quickly and have no lasting effect, while others can remain active for months, preventing new weeds from growing. Short-residual herbicides are suitable for areas where you plan to replant soon, while long-residual herbicides are ideal for areas where you want prolonged weed control. Consider your planting schedule and the need for long-term weed prevention when selecting residual activity.
Environmental ImpactHerbicides can have varying levels of environmental impact. Some are designed to break down quickly and have minimal impact on the environment, while others can persist and potentially harm non-target plants, animals, and water sources. Look for herbicides that are labeled as environmentally friendly or have low toxicity if you are concerned about the impact on your surroundings. Consider the proximity to water sources, wildlife, and other sensitive areas when evaluating environmental impact.
Weed SpectrumThe weed spectrum refers to the range of weed species that the herbicide can control. Some herbicides are broad-spectrum and can control a wide variety of weeds, while others are narrow-spectrum and target specific types. Broad-spectrum herbicides are useful for general weed control, while narrow-spectrum herbicides are better for targeting specific problem weeds. Identify the types of weeds you are dealing with and choose a herbicide that effectively targets those species.
