Nufarm Change Up: Premium Selective Herbicide
Nufarm Change Up is positioned as a premium selective herbicide designed to deliver robust control over more than 200 broadleaf weeds, including oxalis. It features labeled tolerance across a wide range of cool- and warm-season turfgrasses, making it suitable for residential lawns, commercial lawns, and other turf settings. The product emphasizes broad turf compatibility, allowing application in various turf types without excessive risk to desired grass.
Key features include broad-spectrum broadleaf weed control and turfgrass tolerance. When applying, follow label rates and timing guidance to optimize control while protecting desirable grasses. For best results on oxalis, coordinate with proper mowing height and irrigation practices to support herbicide activity and weed uptake.
Monterey Spurge Power (1 Pint)
Monterey Spurge Power combines three active ingredients to address broadleaf weeds including oxalis. It is formulated for post-emergent use and is designed for both warm- and cool-season lawns, covering common grasses like bluegrass, fescue, ryegrass, bentgrass, and Bermuda varieties. This product targets stubborn broadleaf invaders while generally minimizing stress to turf when applied according to label directions.
Users should consider spray timing during active weed growth and ensure thorough coverage of emerging oxalis patches. As with all selective herbicides, calibrate sprayer to apply even misting rather than heavy spot treatments to avoid turf stress. Always wear appropriate protective equipment and observe re-entry intervals as recommended by the label.
Monterey Spurge Power (8 oz)
This smaller 8-ounce bottle variant offers the same three-active-ingredient formulation as the pint size for targeted use or smaller lawn areas. It is suitable for homeowners who need to treat patch-by-patch oxalis clumps or for routine maintenance in mixed turf. As with larger volumes, ensure accurate mixing, label-compliant rates, and uniform coverage to maximize control while protecting grass health.
Atticus Torocity Herbicide
Torocity is a mesotrione-based selective herbicide designed for lawn and turf use, marketed as a flexible pre- and post-emergent option. It targets a broad spectrum of weeds, including oxalis and dandelion, with a focus on timing forgiveness—allowing some application flexibility to catch emerging weeds. The product is positioned as a trusted option for newly seeded areas and established turf alike, offering a reliable tool in weed management programs.
Whitetail Institute Arrest Max
Arrest Max is specifically developed for deer food plots, offering selective grass control with consideration for forage crops. It aims to suppress broadleaf and grassy weeds while supporting the growth of preferred forage species. For users integrating weed control into managed food plots, Arrest Max provides a targeted approach that minimizes unintended damage to clover or alfalfa plantings commonly used in these plots.
Buying Guide: Key Purchase Considerations and Comparisons
- Weed spectrum and selectivity: Choose a product whose labeled target weeds align with oxalis and other problem species in your lawn or plot. Some formulations emphasize broadleaf control, while others provide broader grass safety in the same area.
- Turf compatibility: Check the labeled tolerance for your grass types (bluegrass, fescue, bermudagrass, zoysia, etc.). A product with strong turf tolerance reduces the risk of crop injury or turf discoloration.
- Application timing: Consider whether a pre-emergent, post-emergent, or flexible pre/post approach suits your weed cycle. Products offering timing forgiveness can be advantageous for busy schedules.
- Volume and cost efficiency: Larger volumes may be more economical per acre, but consider the size of the treatment area and frequency of applications to determine true cost efficiency.
- Safety and compatibility: Review any regional label restrictions (such as certain states limiting sales or use). Ensure compatibility with existing lawn care programs and fertilizers.
- Re-entry and watering instructions: Note required waiting periods before foot traffic or irrigation after application to avoid exposure or wash-off.
- Resistance management: Rotate active ingredients when possible to reduce weed resistance risk and maintain long-term efficacy.
When evaluating options, compile a simple comparison based on weed targets, turf compatibility, and application flexibility. For oxalis-heavy lawns, products with proven oxalis control in post-emergent use and broadleaf activity are often most effective, particularly when paired with proper lawn care practices like mowing height management, aeration, and balanced irrigation.
