Buying Guide for Weed Killers in Pastures
Choosing the right weed killer for your pasture requires consideration across several factors to ensure effective control of unwanted plants while preserving desirable grasses.
Target Weed and Brush Types
Identify the prevalent troublesome weeds in your pasture—broadleaf weeds, thistles, woody brush, or vines. Products like Southern Ag Amine 2,4-D and Hi-Yield 2,4-D excel against broadleaf weeds, while Remedy Ultra and Southern AG Brush Weed Killer are designed for woody brush and vine control. Monterey Thistledown is highly effective for specific thistle species.
Selectivity and Safety
Look for herbicides that are selective, meaning they target weeds without harming your pasture grass. Most 2,4-D products are selective for grasses. Remember to avoid products that may harm sensitive ornamentals or vegetable plants if these are nearby. Always follow label instructions for safe application sites and times.
Application Rate and Coverage
Consider the product’s coverage per container and application rates. Economical use rates, such as 1 to 4 pints per acre found in Southern Ag 2,4-D, can extend the product’s use over larger areas. Concentration and formulation impact whether you will apply via sprayer, mix with other herbicides, or need additional spreader stickers.
Environmental Impact and Residual Effects
Pasture herbicides vary in odor, residual soil activity, and effects on non-target species. Products like Remedy Ultra have low odor and long-lasting control on roots and tops. Consider product breakdown time for timing subsequent planting or grazing. Avoid contamination of water sources and carefully read precautions for irrigation ditches.
Compatibility With Other Herbicides
Some herbicides allow tank-mixing for enhanced control, such as Remedy Ultra with GrazonNext. Combining products can broaden weed control but requires adherence to label guidance on safe mixtures and timing.
Ease of Use and Application Equipment
Ease of mixing and applying the herbicide varies. Ready-to-use or concentrated liquids require different sprayer setups. Products like Southern Ag Brush Weed Killer highlight ease of use and stump treatment capabilities. Evaluate your equipment compatibility before purchase.
