Atticus Torocity Herbicide (8oz) — Dual Pre and Post Emergent
Torocity by Atticus leverages 40.0% mesotrione, the same active ingredient trusted in established weed control. It offers timing forgiveness with both pre- and post-emergence activity, expanding the application window beyond pre-emerge-only products. This broad-spectrum option targets many common lawn weeds, including crabgrass, clover, dandelion, oxalis, and ground ivy, making it suitable for newly seeded areas and mature turf alike. Apply when weeds are actively growing for best results, and monitor regrowth in subsequent seasons to maintain a weed-free lawn.
BASF Drive XLR8 Crabgrass Killer
Drive XLR8 blends a potent active ingredient with a water-based formulation for efficient uptake and rapid action. It provides up to 30 days of residual control, helping keep turf free from troublesome weeds between applications. The product is designed for post-emergent use on lawn and turf areas and demonstrates broad-spectrum weed control, tackling crabgrass, foxtail, and various broadleaf weeds. Its quick rainfast performance minimizes wash-off after inclement weather, making it a practical option for variable climates.
Agrisel Sulfentrazone 4F Weed Killer
Agrisel offers a versatile 8-ounce format with pre-emergent and post-emergent activity, targeting 100+ weeds in a single product. The low usage rates help keep costs down while delivering broad-spectrum weed control. This solution is adaptable for residential lawns, golf courses, roadside areas, and even pre-planting crop spaces, making it a flexible choice for property managers seeking comprehensive weed suppression across diverse settings.
Recognition Post-Emergent Herbicide
Recognition emphasizes turf safety with the safener Metcamifen, supporting use on St. Augustinegrass, zoysiagrass, kikuyugrass, and buffalograss in residential and non-residential settings. It delivers powerful control of sedges, broadleaf weeds, and certain grasses when applied at labeled rates. The product also functions well as a tank-mix partner with Turflon Ester Ultra to target additional weed species, providing a flexible approach for complex weed scenarios in larger landscapes.
Sedgehammer Herbicide
Sedgehammer is a dedicated nutsedge killer designed for use in established lawns and other non-crop areas. It works by moving through the plant to affect underground growing points in rhizomes and tubers, helping suppress nutsedge and related sedges with precision. This product is well-regarded for targeted control in lawns, athletic fields, golf courses, and similar turf settings. It can also suppress green kyllinga, making it a useful tool for sedge-heavy landscapes.
Atticus Sertay Herbicide
Sertay, with 75% sulfosulfuron, targets tough Poa annua and provides post-emergent control for southern lawns. It works on grasses, broadleaf weeds, and sedges like sedge and kyllinga. Applicators are advised to apply during warm, moist conditions to improve uptake and effectiveness, especially in actively growing young Poa. As with any sulfosulfuron-containing product, follow label directions and consider irrigation timing to maximize performance and minimize stress on desirable grasses.
Honcho K6 Post-Emergent Herbicide
Honcho K6 provides a powerful non-selective, post-emergent option with glyphosate as the active ingredient. It is designed for tough weed control in woody and brush areas and is suitable for applications on large areas where broadleaf weeds and woody growth threaten turf boundaries. Its concentrated formula supports robust control across challenging weed species, making it a reliable option for property managers dealing with mixed weed populations.
Buying Guide: Key Purchase Considerations
- Active ingredient and weed targets: Match products to the primary weeds in your turf (nutsedge, crabgrass, broadleaf weeds, sedges). Some formulations offer pre- and post-emergent activity, while others excel at specific weed classes.
- Turf safety and site type: Consider safeners and label guidance for your grass type (St. Augustinegrass, zoysiagrass, bermudagrass, etc.) and non-turf areas like golf courses or golf course roughs.
- Timing and application window: Products with broader application timing provide flexibility in scheduling, especially in climates with variable weed germination patterns.
- Residual control: If weeds reoccur frequently, products with extended residual effects can reduce the need for frequent reapplications, but balance with potential impacts on turf recovery after stress periods.
- Environmental and usage considerations: Some formulations are designed for lawns, while others are suitable for roadside or public areas. Consider safety for pets and children, and follow label directions for watering and re-entry intervals.
- Tank mixing and compatibility: Tank-mix options can simplify management but require checking compatibility and label restrictions to avoid unintended turf damage.
When planning a weed-control strategy, combine cultural practices (mowing height, irrigation management, and soil health) with selected post-emergent products to optimize turf resilience. Always read and follow the product label for rate, timing, and safety considerations to ensure effective and responsible weed control across your lawn or turf project.
