10 Best Herbicide For Pastures 2025 in the United States

Round Up Pro Concentrate is a widely-used herbicide with an active ingredient of 50.2% Glyphosate. This non-selective herbicide effectively controls a broad range of unwanted weeds in various settings, from agricultural farms to residential areas and industrial sites. The systemic nature of Glyphosate means that it is absorbed by plants and moves throughout, killing them completely.

One of the key strengths of this product is its quick rainfastness, being resistant to wash-off just an hour after application, which is particularly useful in unpredictable weather conditions. The 2.5-gallon jug format also ensures that it can cover large areas efficiently. However, being a non-selective herbicide, Round Up Pro will kill almost any plant it comes into contact with, which can be a drawback if not used carefully.

Furthermore, while Glyphosate is effective, its environmental impact is a point of concern as it can potentially affect non-target species and contribute to long-term soil health issues. It is important to follow proper application timing and guidelines to mitigate these environmental risks. This product is particularly suitable for those who need a reliable, fast-acting solution for large-scale weed control and are comfortable managing its non-selective nature and potential environmental effects.

The Dow AgroSciences RTU548 Tordon RTU Herbicide is a ready-to-use liquid herbicide designed mainly for controlling unwanted trees and brush in non-crop areas like fence lines, roadsides, and forest boundaries. Its key strength lies in its targeted application method—applying it directly to cut stumps helps effectively kill regrowth without spraying large areas, which minimizes impact on surrounding plants. This precise use means it’s selective and suitable for maintaining pastures without harming desirable grasses. The product’s coverage allows treatment of around 50 to 100 stumps per quart depending on stump size.

Tordon products typically contain picloram, known for longer residual activity that keeps treated areas free from regrowth for a while, which can be a plus for pasture management but requires careful use to avoid affecting nearby sensitive plants. Application timing is flexible as it targets cut stumps rather than foliar spraying, making it practical for spot treatments as needed. Environmental impact should be considered because long residual activity means it can persist in soil and potentially affect nearby non-target vegetation if not used carefully.

This herbicide serves as a strong choice for controlling woody plants in pastures and non-crop fence lines, especially for those wanting a ready-to-use product with proven effectiveness. Users should follow instructions carefully to reduce environmental risks.

The Hi-Yield (21416) 2,4-D Selective Weed Killer is a reliable choice for managing broadleaf weeds in pastures, rangelands, and other areas. Its active ingredient, 2,4-D acid, is effective against common weeds like Dandelion, Arrowhead, Buckhorn, and Aster. This selective herbicide targets broadleaf weeds while sparing grasses, making it suitable for pasture use.

The product is easy to apply and is compatible with Hi-Yield Spreader Sticker for enhanced effectiveness, ensuring thorough weed control. The product also covers a large area, which is beneficial for expansive pasturelands. Application timing and rates are crucial, so it's best to follow the label instructions to avoid any potential harm to desirable plants.

It is important to consider the environmental impact, as 2,4-D can affect aquatic life; therefore, care should be taken when using near ponds and waterways. This product is not discontinued and is well-ranked among weed killers. The Hi-Yield 2,4-D Selective Weed Killer is effective for pasture weed management but requires careful application to minimize environmental impact.
