RM43 Total Vegetation Control is a powerful herbicide designed to eliminate unwanted plants and prevent regrowth for up to one year. It combines glyphosate and imazapyr for long-lasting results.
1.1 Overview of RM43 and Its Purpose
RM43 Total Vegetation Control is a highly effective herbicide designed to eliminate unwanted plants and prevent their regrowth for up to one year. It is a combination of two active ingredients: glyphosate, which kills existing vegetation, and imazapyr, which inhibits seed germination and sprouting. This dual-action formula ensures long-lasting control over weeds and other unwanted plants. RM43 is commonly used for bareground applications, such as fence lines, roadsides, and industrial areas, where no vegetation is desired. The product is also rainfast within two hours of application and leaves no residual soil activity, making it safe for areas where people or pets may frequent; Its versatility and potency make it a popular choice for both residential and commercial use.
1.2 Importance of Proper Mixing Instructions
Proper mixing of RM43 is crucial for effective results and safety. Incorrect ratios can lead to reduced efficacy or potential harm to desirable plants. The recommended mix for total vegetation control is 7.4 ounces of RM43 per gallon of water, while spot control requires 6 ounces per gallon. Adhering to these guidelines ensures optimal herbicide performance and prevents over-application, which could damage the environment or non-target plants. Proper mixing also maintains the product’s integrity, preventing separation or uneven distribution. Always wear personal protective equipment, such as gloves and eye protection, when handling the product. Following the instructions carefully guarantees the best outcome and minimizes risks associated with herbicide use.
Mixing Ratios for Different Applications
For effective weed control, RM43 is mixed at 7.4 oz per gallon for total vegetation control and 6 oz per gallon for spot control, covering up to 1,000 square feet with 1-10 gallons of solution.
2.1 Total Vegetation Control Mix Ratio
The recommended mix ratio for total vegetation control is 7.4 fluid ounces of RM43 per gallon of water. This concentration ensures complete elimination of unwanted plants and prevents regrowth for up to one year. When applied correctly, it covers approximately 1,000 square feet, making it ideal for large areas like driveways, fence lines, and industrial sites. The solution should be uniformly sprayed using hand-operated or mounted sprayers. Always mix with clean water, and adjust the volume between 1 to 10 gallons based on your equipment and application rate. Proper mixing is crucial for effectiveness and safety, so follow the instructions carefully to achieve optimal results.
2.2 Spot Control Mix Ratio
For spot control applications, the recommended mix ratio is 6 ounces of RM43 per gallon of water. This concentration is ideal for targeting individual weeds or small areas where selective vegetation control is needed. It ensures precise application without affecting surrounding plants. When using this ratio, apply the solution directly to the foliage of the target weeds until they are thoroughly wet. This method is effective for managing specific problem areas while minimizing herbicide use. Always ensure the solution is applied to actively growing weeds for the best results. The spot control mix is a cost-efficient way to maintain smaller spaces without treating entire areas. Proper application ensures safety and effectiveness, making it suitable for yards, gardens, and other non-crop spaces.
Application Methods for RM43
RM43 can be applied using hand-operated sprayers, backpack sprayers, pump sprayers, or ATV/tractor-mounted equipment. These methods ensure uniform coverage for effective weed control across various areas.
3.1 Using Hand-Operated Spray Equipment
Hand-operated spray equipment, such as backpack sprayers or pump sprayers, is ideal for precise application of RM43; Fill the sprayer with the recommended mix of 7.4 oz of RM43 per gallon of water for total vegetation control or 6 oz for spot treatment. Ensure the nozzle is set to a fine spray to cover the target area evenly. Walk steadily, holding the wand 12-18 inches above the foliage, and spray uniformly to wet leaves thoroughly. This method is effective for smaller areas or where larger equipment cannot reach. Always follow the label instructions for optimal results and safety. Proper application ensures long-lasting weed control and prevents regrowth for up to a year.
3.2 Using ATV/Tractor Mounted Sprayers
For larger areas, ATV or tractor-mounted sprayers are ideal for applying RM43. Begin by filling the tank with water and adding the recommended 7.4 oz of RM43 per gallon for total vegetation control or 6 oz for spot treatments. Ensure the sprayer is calibrated to deliver the correct application rate. Attach the spray boom or nozzle setup, adjusting the height to 12-18 inches above the target area. Operate at a steady speed to maintain uniform coverage, typically spraying at pressures between 20-40 PSI. This method is efficient for covering vast spaces like fields or fence lines. Always follow the label instructions and safety precautions to achieve optimal results and prevent overspray on desirable plants. Proper application ensures long-lasting control and prevents weed regrowth for up to one year.
Safety Precautions and Protective Gear
Wear long sleeves, pants, closed-toe shoes, chemical-resistant gloves, goggles, and a face mask. Follow EPA guidelines for category A on the chemical-resistance selection chart to ensure safety.
4.1 Personal Protective Equipment (PPE) Requirements
Wearing proper PPE is crucial when handling RM43 to ensure safety. This includes long sleeves, pants, closed-toe shoes, chemical-resistant gloves, goggles, and a face mask. Follow EPA category A guidelines for chemical resistance. Avoid skin and eye contact, as RM43 is potent. Ensure all protective gear is worn during mixing, loading, and application to minimize exposure risks; Additionally, the herbicide is rainfast within two hours of application, meaning no entry restrictions apply for people or pets afterward. Always refer to the product label for detailed PPE requirements and safety precautions to handle RM43 effectively and safely.
Coverage Area and Application Rates
RM43 provides effective coverage depending on the mixing ratio and application method. For total vegetation control, 7.4 fl. oz. of RM43 mixed with 1–10 gallons of water covers approximately 1,000 square feet. This solution is ideal for larger areas like fence lines, paths, and open spaces. For spot control, 6 fl. oz. of RM43 per gallon of water is sufficient, targeting smaller, specific areas. The maximum application rate is 7.4 fl. oz. of product per 1,000 square feet annually. Ensure uniform spraying to achieve optimal results. Applying the solution when weeds are actively growing, typically in early summer, enhances effectiveness. Proper coverage ensures long-lasting control, preventing regrowth for up to a year. Always follow label instructions to avoid over-application and maintain environmental safety.
Best Practices for Mixing and Applying RM43
For optimal results with RM43, start by wearing appropriate PPE, including gloves and eye protection. Begin by filling your sprayer tank with clean water, then add the recommended amount of RM43 concentrate. Stir the mixture thoroughly for 5–10 minutes to ensure even distribution. Apply the solution uniformly, targeting actively growing weeds in early summer for best efficacy. Avoid spraying during windy or rainy conditions to prevent drift and runoff. For total vegetation control, apply 7;4 fl. oz. of RM43 per 1,000 square feet, using 1–10 gallons of water depending on your sprayer type. For spot control, use 6 fl. oz. per gallon of water. Always follow the manufacturer’s guidelines and local regulations to ensure safe and effective application.
Additional Tips for Effective Weed Control
To maximize the effectiveness of RM43, apply it during optimal weather conditions, such as sunny, windless days, to ensure proper absorption and minimize drift. Ensure thorough coverage by using the correct spray nozzle and maintaining a consistent walking or driving speed. For hard-to-reach areas, consider using hand-operated sprayers for precise application. Regularly inspect and clean your equipment to prevent clogging and maintain performance. After application, avoid watering treated areas for at least 24 hours to allow the herbicide to take effect. For long-term results, reseed or replant only after the recommended waiting period, typically several months, to ensure the area is weed-free. These tips enhance the efficacy of RM43 and help achieve lasting vegetation control.
