Speed Zone Weed Killer is a fast-acting, 4-way herbicide containing 2,4-D, mecoprop-p, dicamba, and carfentrazone. Effective against broadleaf weeds like clover, dandelions, and plantain. Labeled for use on cool-season turfgrasses such as Kentucky bluegrass, perennial ryegrass, and tall fescue.

Application Instructions

Apply Speed Zone Weed Killer evenly using broadcast or spot treatments. Follow label instructions for proper spraying techniques and equipment setup to ensure effective weed control.

2.1. Broadcast Treatments

For broadcast treatments, apply Speed Zone Weed Killer evenly across the entire lawn using a sprayer. Ensure thorough coverage to target all broadleaf weeds effectively. The product is labeled for use on cool-season turfgrasses, such as Kentucky bluegrass, perennial ryegrass, and tall fescue. Spray when weeds are actively growing and during calm conditions to minimize drift. Use flat fan nozzles for optimal results. The recommended application rate ensures control of weeds like clover, dandelions, and plantain without harming the grass. Avoid applying during extreme heat or when turf is under stress. Allow the product to dry completely before irrigation or rainfall. Broadcast treatments are most effective when applied in the fall for improved control of certain weeds like clover. Always follow label instructions for the best outcomes and to maintain turf health.

2.2. Spot Treatments

For spot treatments, Speed Zone Weed Killer can be applied directly to individual weeds or small clusters using a hand sprayer. This method is ideal for isolated weed growth, reducing the amount of product needed and minimizing exposure to healthy grass. Apply the solution at a rate of 1 ounce per gallon of water, ensuring thorough coverage of the target weeds. Avoid overspray on desirable plants, as the herbicide may cause damage. Spot treatments are particularly effective for controlling weeds like dandelions, clover, and plantain. For best results, treat weeds during active growth and under calm conditions. Allow the product to dry completely before watering or mowing. This targeted approach helps maintain a healthy lawn while managing weed populations efficiently.

Mixing Guidelines

Speed Zone Weed Killer should be mixed at 1 oz per gallon of water. Agitate the spray tank thoroughly and maintain continuous agitation during application.

3.1. Correct Ratio (1 oz per gallon)

For optimal effectiveness, mix Speed Zone Weed Killer at a ratio of 1 ounce per gallon of water. This ensures proper concentration for targeting weeds without harming turf. Always measure accurately to avoid under or over-application. Using less than 1 oz per gallon may reduce weed control efficacy, while exceeding this ratio can stress or damage grass. The 1 oz per gallon ratio is specifically designed to balance effectiveness and safety for cool-season turfgrasses like Kentucky bluegrass, perennial ryegrass, and tall fescue. Maintain this ratio whether applying as a broadcast treatment or spot treatment to ensure consistent results. Proper mixing is critical for achieving the desired weed control while protecting your lawn.

3.2. Agitation Requirements

Proper agitation is essential when mixing Speed Zone Weed Killer to ensure the active ingredients remain evenly distributed. Before application, thoroughly agitate the mixture to prevent separation of the emulsion. When preparing the spray solution, add the required amount of Speed Zone to water in the tank while maintaining continuous agitation. This step is crucial to avoid settling and ensure uniform application. During spraying, keep the agitation active, especially if using flat fan nozzles, to maintain consistency. Proper agitation ensures effective weed control and prevents damage to the turfgrass. Always follow the label instructions for agitation to achieve optimal results and lawn safety.

Tank Mixing with Other Herbicides

Tank mixing Speed Zone Weed Killer with other herbicides requires careful consideration to avoid potential interactions. It is generally not recommended to mix Speed Zone with herbicides like Triclopyr, as Speed Zone is a 4-way herbicide already formulated for broadleaf weed control. However, if tank mixing is necessary, ensure compatibility by consulting the product labels and following all safety precautions. Always conduct a small-scale test before applying tank-mixed solutions to ensure no adverse reactions occur. Over-application or improper mixing can damage turfgrass or reduce effectiveness. When mixing, maintain proper agitation to keep the solution uniform. Prioritize using Speed Zone alone for most broadleaf weed control needs, as its formulation is designed for comprehensive coverage without additional herbicides.

Waiting Period Before Reseeding

After applying Speed Zone Weed Killer, it is essential to wait at least two weeks before reseeding. This allows the herbicide to degrade in the soil, reducing the risk of harming new seedlings. The product label specifies this waiting period to ensure safe reseeding without interfering with the herbicide’s effectiveness. During this time, mow the lawn at least twice to promote healthy turfgrass recovery. Properly preparing the soil before reseeding, such as loosening the soil and applying a starter fertilizer, will help establish new grass effectively. Always follow the label instructions to avoid any potential damage to your lawn. Reseeding too soon can lead to poor germination or stunted growth due to residual herbicide activity. Patience during this waiting period ensures a successful lawn renovation.

Effectiveness on Specific Weeds

Speed Zone Weed Killer is highly effective against a wide range of broadleaf weeds, including clover, dandelions, and plantain. It is particularly noted for its ability to control creeping charlie due to its active ingredient, carfentrazone. Wild violets, however, may require multiple applications for optimal control, as initial treatments may only cause temporary damage. The herbicide works quickly, often showing visible results within hours, but full control of certain weeds like violets may take several weeks. For tough-to-control species, follow-up treatments are recommended to ensure complete eradication. The product is most effective when applied during active weed growth, typically in spring or fall. Always ensure proper application and timing to maximize its effectiveness on target weeds while minimizing impact on desirable turfgrass.

Proper Spray Nozzle Selection

Proper spray nozzle selection is crucial for effective application of Speed Zone Weed Killer. Flat fan nozzles are recommended for optimal coverage, especially when wind conditions are calm and favorable. Drift reduction nozzles should generally be avoided unless necessary, as they may reduce the product’s efficiency. The nozzles should be chosen to ensure an even distribution of the herbicide, minimizing drift and overspray. It’s important to maintain the recommended spray pressure to achieve the desired droplet size, which helps in accurate targeting of weeds. Always clean and calibrate the nozzles before use to ensure consistent performance. Proper nozzle selection and maintenance are key to achieving the best results while protecting desirable turfgrass from unintended damage.

Seasonal Application Timing

Seasonal application timing plays a vital role in the effectiveness of Speed Zone Weed Killer. For optimal results, apply the herbicide during the active growth stages of target weeds. Fall applications are particularly effective for controlling broadleaf weeds like clover, as cooler temperatures enhance uptake. Spring and early summer applications are ideal for addressing weeds like dandelions and plantain. Avoid applying during extreme heat or drought, as this can stress turfgrass. Post-emergent applications should be made when weeds are young and actively growing. For best results, apply in the early morning or late afternoon to minimize evaporation and ensure better absorption. Fall treatments are also recommended for pre-emergent control of certain weeds, ensuring a healthier lawn in the following spring. Always consider local weather conditions and turfgrass type before applying.

Coverage Area and Usage

Speed Zone Weed Killer is designed to cover large areas efficiently, with a single application typically treating between 14,000 to 18,000 square feet. This makes it ideal for homeowners with extensive lawns or commercial properties. The product is highly concentrated, requiring precise measurement to ensure optimal coverage without over-application. For broadcast treatments, mix the recommended amount with water in a spray tank and apply evenly across the lawn. For smaller areas or spot treatments, adjust the mixture ratio accordingly to avoid wasting product. The herbicide is suitable for most cool-season turfgrasses, including Kentucky bluegrass, perennial ryegrass, and tall fescue. Always ensure even distribution to achieve consistent weed control and maintain lawn health. Proper usage ensures effective results while minimizing environmental impact.

Visible Results Timeline

Speed Zone Weed Killer delivers rapid results, with visible effects often appearing within hours of application. Weeds typically begin to wilt and show signs of discoloration within 12-24 hours. Full control of targeted broadleaf weeds, such as dandelions and clover, is usually achieved within 1-2 weeks. For tougher weeds like wild violets, it may take up to 3-4 weeks to assess complete effectiveness. Users should wait at least 3-4 weeks before determining if a follow-up application is necessary. The product works quickly to eliminate unsightly weeds, allowing lawns to recover and regain their healthy appearance. This rapid action makes Speed Zone a popular choice for homeowners seeking efficient weed control solutions. Always follow label instructions to ensure optimal results and avoid over-application.
