Nufarm Change Up, Premium Selective Herbicide
Nufarm Change Up is designed for premium selective control, including oxalis, among more than 200 broadleaf weeds. It offers broad turfgrass tolerance, making it suitable for cool- and warm-season grasses such as Kentucky bluegrass, fescue, bermudagrass, and St. Augustinegrass. This product is best for homeowners and property managers seeking robust broadleaf weed suppression without harming common lawn grasses.
Best for: Home lawns and commercial turf where oxalis is a persistent weed and turf compatibility is essential. Choose this if you want a broad-spectrum result with minimal turf damage. A caution: ensure your turf type is listed on the label before application, as misapplication can affect sensitive grasses.
Monterey Spurge Power Bundled with Measuring Spoon (1 Pint)
Monterey Spurge Power combines three active ingredients to control broadleaf weeds, including oxalis, dandelion, clover, and creeping Charlie. It is effective in both warm- and cool-season lawns, covering a broad spectrum of common yard weeds while maintaining turf health. The bundled measuring spoon helps with accurate mixing for consistent results.
Best for: A versatile option for homeowners who want reliable oxalis control alongside other broadleaf targets, with compatibility across a range of lawn types. Limitation: the product works best when used as directed; misapplication can limit effectiveness or affect desirable grasses.
Monterey Spurge Power Bundled with Measuring Spoon (8 oz)
This smaller bottle of Spurge Power provides the same three-active-ingredient formula in a compact package, suitable for spot treating localized weed patches or for users with smaller lawn areas. It remains a strong option for oxalis control alongside other common broadleaf weeds.
Best for: Homeowners who want a cost-effective, smaller-volume option for targeted oxalis and broadleaf weed control. Limitation: may require more frequent applications for larger lawn areas or heavily infested spots.
Atticus Torocity Herbicide (8 oz)
Torocity uses mesotrione, the same key active ingredient associated with effective, trusted weed control in both newly seeded and established turf. It supports flexible timing with pre- and post-emerge activity and targets a broad spectrum of weeds including oxalis, making it a strong choice for those needing a broader application window and robust weed suppression.
Best for: Lawns where timing flexibility matters, especially if oxalis is a recurring issue. Caution: always follow label timing guidelines to optimize pre- and post-emerge performance and avoid turf stress in sensitive areas.
Whitetail Institute Arrest Max Selective Grass Control
Arrest Max is specifically developed for deer food plots and focuses on selective broadleaf weed and grass control compatible with forage systems. It supports weed management while safeguarding the intended grasses and forages used in food plots. This product is best for land managers balancing weed control with wildlife planting goals.
Best for: Deer food plots and similar forage-based plantings where weed control must align with forage maintenance. Limitation: designed for specialty plots; may not be the most practical choice for typical home lawns where oxalis is the primary concern.
Buying Guide
What should I look for in a selective herbicide for oxalis?
Key factors include turf tolerance, target weed spectrum, timing flexibility, and application method. Look for products labeled for oxalis control, and ensure your grass type is listed on the label to avoid turf injury. Consider whether you need a broadleaf-only approach or a product that also handles other weed groups.
Which product is best for my lawn type?
- Cool-season grasses (bluegrass, fescue): Choose products labeled for cool-season tolerance, such as those with broadleaf weed control suitable for these grasses.
- Warm-season grasses (bermudagrass, zoysia): Opt for formulations labeled for warm-season turf that maintain vigor while suppressing oxalis and other weeds.
- Spot treatments vs. whole-lawn applications: Smaller packages (8 oz) are ideal for targeted patches; larger bottles cover broader areas more efficiently.
How do I apply safely and effectively?
- Always read and follow the label directions, including temperatures, growth stage considerations, and watering instructions after application.
- Apply when weeds are actively growing for best uptake and movement within plant tissues.
- Inspect treated areas after 2–4 weeks to determine if a second application is warranted and safe for the lawn.
What are common limitations or cautions?
- Some products have regional restrictions or are not available in certain states. Check local regulations on sale and use.
- Some formulations may affect particular turf types or forages; avoid spraying on desirable grasses or forage crops not listed on the label.
- Spot treatments can be more precise but may require multiple applications for complete oxalis suppression in heavily infested zones.
How should I compare these products side by side?
- Turf compatibility: Confirm labeled grass species for each product.
- Weed spectrum: Identify whether the target list includes oxalis and other weeds you face.
- Application timing: Note whether pre-emerge, post-emerge, or both are supported.
- Package size and cost-effectiveness: Larger bottles generally offer lower cost per treatment.
