Nufarm Change Up Selective Herbicide
Nufarm Change Up is positioned as a premium selective herbicide designed to control more than 200 broadleaf weeds, including oxalis, while maintaining turfgrass tolerance. It is labeled for a wide range of cool- and warm-season grasses like Kentucky bluegrass, Bermuda grass, fescue, and more. Ideal for residential and commercial lawns, Change Up aims to balance robust weed control with turf safety. Application timing and rate should follow label guidelines to maximize oxalis suppression without stressing desirable grasses. This product is suitable for established lawns experiencing moderate weed pressure and can be part of an ongoing weed-management program.
Monterey Spurge Power (1 Pint)
Spurge Power from Monterey provides post-emergent, selective broadleaf weed control with three active ingredients targeting weeds like oxalis, dandelion, and spurge. It is described as suitable for both warm- and cool-season lawns including bluegrass, fescue, ryegrass, and bermudagrass. The bundled measuring spoon helps ensure precise dosing. For oxalis, this product offers targeted suppression while preserving turf when used according to label directions. Consider weather and mowing schedules to optimize efficacy and minimize turf stress after application.
Monterey Spurge Power (8 oz)
The 8-ounce version of Spurge Power offers the same broadleaf weed control benefits in a smaller package, making it a practical choice for homeowners who manage smaller lawns or want to test the product before committing to larger quantities. It targets oxalis and other common broadleaf lawn weeds while supporting compatibility with a range of turfgrasses. As with the pint size, follow label instructions for timing, application rate, and protective measures to minimize turf injury and maximize weed suppression outcomes.
Atticus Torocity Herbicide
Torocity from Atticus uses 40% mesotrione—the same active ingredient found in Tenacity—to deliver broad-spectrum weed control in lawns and turf. It supports flexible timing with pre- and post-emergent activity, enabling treatment windows that can accommodate newly seeded or mature lawns. Oxalis control is among the weed targets, but efficacy can depend on weed size and turf health. This product suits homeowners seeking a versatile option that can suppress both annual bluegrass and other broadleaf species alongside oxalis, with careful attention to label specifics and safety precautions.
Whitetail Institute Arrest Max
Arrest Max is a selective grass-control product designed for deer food plots but is also used in managed turf scenarios. It aims to reduce grass competition while preserving the broader lawn plantings such as clover or alfalfa in compatible settings. When considering oxalis, Arrest Max may contribute to overall weed management in mixed plantings, though it is essential to verify turf compatibility and any crop-specific restrictions. This option provides a targeted approach for weed control in specialty plots or multi-species landscapes, with appropriate safety and timing considerations.
Buying Guide: Key Purchase Considerations And Comparisons
- Turf compatibility: Check whether the product is labeled for cool- or warm-season grasses in your region, and confirm it is suitable for your specific lawn mix to avoid damage.
- Weed spectrum: If oxalis is your primary target, verify that the product provides strong oxalis suppression and also controls other common broadleaf weeds you encounter.
- Application timing: Some products are pre- or post-emergent, while others offer flexible timing. Plan around weed growth stage and your mowing schedule to maximize efficacy.
- Active ingredients: Mesotrione-based options (like Torocity) offer flexibility but require careful use with newly seeded lawns. Compare with concentrates (Spurge Power) that provide adjustable dosing for larger areas.
- Form and packaging: Larger bottles may be cost-effective for bigger lawns, while smaller sizes are convenient for trial use or smaller plots. Ensure you have the proper measuring tools and safety gear.
- Safety and restrictions: Some products have regional sales restrictions or require EPA registrations. Always follow label instructions and local regulations, particularly on sensitive turf varieties and seasonal timing.
- Environmental considerations: Consider impact on non-target plants and nearby ornamentals. Use spot treatments or targeted applications when possible to minimize collateral effects.
- Reapplication window: Some products allow multiple applications per season; others require longer intervals. Plan a weed-management schedule that aligns with growth cycles and weather conditions.
