Tenacity Turf Herbicide 8 oz by Syngenta Systemic Weed Killer for Lawn

Description

Product Overview

Tenacity Turf Herbicide is a professional‑grade, systemic solution designed specifically for the selective control of a broad spectrum of weeds that threaten the health and appearance of turfgrass. Formulated by Syngenta, a trusted name in agricultural science, this product combines the powerful active ingredient mesotrione at a 40% concentration with a convenient 8 oz liquid carrier that can be easily mixed and applied using standard spray equipment.

The chemistry of mesotrione works by inhibiting the enzyme 4‑hydroxyphenylpyruvate dioxygenase (HPPD), a pathway essential for carotenoid biosynthesis in susceptible plants. By disrupting this pathway, Tenacity causes rapid bleaching and death of targeted weeds while leaving desirable turfgrass largely unaffected. This mode of action provides both pre‑emergence and post‑emergence activity, giving homeowners and grounds‑keepers the flexibility to treat weeds at different stages of development.

Key specifications include an 8 fluid‑ounce container, a product weight of 8 ounces, and a shelf life of five to eight years when stored in a cool, dry place away from direct sunlight. The formulation is ready‑to‑use after dilution, and the label provides clear guidance on mixing rates, application timing, and safety precautions to ensure optimal performance.

Usage

Tenacity Turf Herbicide is ideally suited for residential lawns, commercial turf, golf courses, and sports fields where a uniform, weed‑free surface is essential. The product can be applied as a pre‑emergent treatment, allowing emerging weed seedlings to absorb the herbicide directly from the soil surface. This early intervention helps prevent the establishment of problematic species such as crabgrass, foxtail, and yellow nutsedge before they become visible.

When used as a post‑emergent, Tenacity targets actively growing weeds, delivering rapid control of broadleaf species like dandelion, clover, and chickweed, as well as grassy weeds that have already emerged. The dual‑mode capability means a single product can cover multiple stages of weed development, reducing the need for separate pre‑ and post‑emergent chemicals and simplifying the overall weed‑management program.

Application rates typically range from 0.5 to 1.0 fl oz per 1,000 sq ft, depending on the severity of infestation and the specific weed species present. For best results, apply Tenacity when soil temperatures are consistently above 55 °F (13 °C) and before the target weeds reach the 2‑leaf stage. Uniform coverage is critical; uneven application can lead to patchy control and may allow some weeds to survive.

Safety considerations include wearing appropriate personal protective equipment (PPE) such as gloves, goggles, and long‑sleeved clothing during mixing and application. The product should be kept out of reach of children and pets, and any runoff should be prevented from entering water bodies to protect aquatic life.

FAQ

What types of weeds can Tenacity control?

Tenacity is effective against many common turf weeds, including crabgrass (both large and smooth varieties), dandelion, yellow nutsedge, foxtail, goosegrass, henbit, purslane, thistle, wild carrot, and a variety of broadleaf species such as clover and chickweed. It targets both grassy and broadleaf weeds, making it a versatile choice for mixed‑species infestations.

Can I use Tenacity on all types of turfgrass?

Tenacity is safe for use on most cool‑season and warm‑season turfgrasses, including Kentucky bluegrass, perennial ryegrass, tall fescue, bermudagrass, zoysiagrass, and St. Augustinegrass. However, it is always recommended to test a small area first and follow label instructions for specific grass species to avoid any unintended injury.

How often should I reapply Tenacity?

For pre‑emergent applications, a single treatment early in the season is often sufficient, but a second application may be needed if weed pressure is high. Post‑emergent treatments can be repeated every 14‑21 days as needed, provided the label’s maximum annual application limits are not exceeded. Always adhere to the recommended rates and timing to maintain efficacy and safety.

Is Tenacity safe for pets and children?

When applied according to label directions and allowed to dry, Tenacity poses minimal risk to pets and children. It is important to keep the treated area off‑limits until the spray has fully dried and to store the product out of reach of children and animals. If accidental contact occurs, rinse the area with water and seek medical advice if irritation persists.

What should I do with leftover product?

Store any remaining Tenacity in its original container, tightly sealed, in a cool, dry place away from direct sunlight and extreme temperatures. Do not dispose of the product in storm drains or waterways. Follow local regulations for hazardous waste disposal if you need to discard the product or its container.
