RM43 Total Vegetation Control⁚ An Overview
RM43 is a powerful herbicide designed for total vegetation control, combining glyphosate for immediate kill and a pre-emergent for long-term prevention. It is particularly effective on hard surfaces like driveways and patios, preventing weeds from growing in cracks.
What is RM43?
RM43 is a total vegetation control herbicide, formulated to both kill existing weeds and prevent new ones from emerging. It’s a combination product that leverages the power of glyphosate for immediate, non-selective weed control, targeting a broad spectrum of unwanted plants. What sets RM43 apart is the inclusion of a pre-emergent component, which creates a barrier in the soil to inhibit the germination of weed seeds for an extended period. This dual-action approach makes it suitable for areas where long-lasting bare ground is desired. RM43 is often used on driveways, patios, and other hard surfaces, making it a versatile solution for various weed control needs. It is known for its high concentration and effectiveness, even though it tends to be more expensive than some other herbicides. It is considered a powerful tool for managing unwanted plant growth.
Active Ingredients⁚ Glyphosate and Pre-Emergent
RM43’s effectiveness stems from its two primary active ingredients⁚ glyphosate and a pre-emergent herbicide. Glyphosate is a non-selective, systemic herbicide that works by inhibiting a specific enzyme essential for plant growth. It is absorbed through the leaves and stems, translocating throughout the plant to kill it from the roots up. This provides a quick knockdown of existing weeds and grasses. The pre-emergent component, on the other hand, is designed to prevent weeds from germinating. It works by creating a chemical barrier in the top layer of the soil, inhibiting the development of new seedlings. This combination of glyphosate for immediate control and a pre-emergent for long-term prevention makes RM43 a comprehensive solution for areas requiring total vegetation control. The specific type of pre-emergent used in RM43 is not always explicitly stated, but it is crucial for its extended control capabilities.
RM43 Application Instructions
Proper application is key to RM43’s effectiveness. This section will detail the mixing ratios, application rates, ideal timing, and various methods to ensure optimal results for total vegetation control.
Mixing Ratios and Dilution
When preparing RM43 for application, understanding the correct mixing ratios and dilution is critical for achieving desired results. The standard recommendation often involves mixing 6 to 7.5 fluid ounces of RM43 concentrate per gallon of water. However, some users have found success with a slightly lower concentration, around 3 ounces per gallon, particularly for maintenance applications or when targeting less dense vegetation. It’s essential to note that regardless of the dilution ratio, the maximum annual application rate should not exceed 2.5 gallons per acre. For smaller areas, this translates to approximately 7.4 fluid ounces per 1,000 square feet per year. Always thoroughly mix the solution in a sprayer and ensure even distribution when applying. Refer to the product label for the most accurate and up-to-date instructions, as specific recommendations may vary.
Application Rate Per Area
The application rate of RM43 is crucial for effective weed control while adhering to safety guidelines. The maximum recommended application rate is 2.5 gallons of the product per acre per year. For smaller areas, this translates to about 7.4 fluid ounces of RM43 concentrate per 1,000 square feet annually. It is important to apply the solution evenly across the target area to ensure thorough coverage. When using a hand-operated sprayer, aim for complete coverage of the vegetation and surrounding soil. Avoid applying excess solution that could run off into unintended areas. While some users might opt for a slightly lower dilution, it is essential not to exceed the maximum yearly application rate to prevent potential environmental harm or reduced effectiveness. Always refer to the product label for the most accurate and updated information on application rates.
Best Time to Apply
The optimal time to apply RM43 is when weeds are actively growing, typically during the early summer months. Applying the herbicide during this period ensures that the active ingredients are readily absorbed by the plants, leading to more effective control. Avoid applying RM43 when weeds are stressed, such as during periods of drought or extreme temperatures, as this can hinder the product’s efficacy. It’s also important to consider the weather forecast before application; avoid spraying when rain is expected within 24 hours, as this can wash away the herbicide before it has had time to take effect. For areas where preventative measures are required, apply RM43 before the weeds germinate, usually in late spring or early summer. This pre-emergent action will help prevent new growth, providing longer-lasting control. In general, aim for a time when there is minimal wind to prevent drift onto non-target plants.
Application Methods
RM43 is typically applied using hand-operated spray equipment, such as backpack sprayers or handheld sprayers. This allows for precise application, especially in targeted areas like cracks in pavement or along fence lines; When applying, ensure even coverage of the area, wetting the foliage of the weeds thoroughly without causing excessive runoff. For larger areas, a tank sprayer may be more efficient, but ensure that the application rate does not exceed 2.5 gallons per acre per year. For spot control of brush, vines, and weeds, a directed spray is recommended, focusing on the unwanted vegetation to avoid harming desirable plants. Always refer to the product label for specific instructions and recommended application techniques. When applying, it is important to avoid spraying on windy days to prevent the herbicide from drifting to non-target areas. Use proper safety equipment, like gloves and eye protection, during application. Do not apply when rain is expected within 24 hours.
RM43 Effectiveness and Limitations
RM43 offers both immediate weed kill and extended control with its pre-emergent component. However, its effectiveness can vary depending on application and environmental conditions. The duration of prevention is not a full 12 months as some expect.
Duration of Control
While RM43 is marketed for long-lasting vegetation control, the actual duration can vary significantly based on several factors. While some users expect a full year of prevention, many report that effective control typically lasts for about three to four months, especially in areas with higher weed pressure or frequent rainfall. The pre-emergent component provides a barrier to new weed growth, but this barrier’s effectiveness diminishes over time. The type of weeds targeted also plays a role, with some species being more resistant or quicker to re-establish. Furthermore, the application method and rate, as well as environmental factors like temperature and moisture levels, will impact how long RM43 remains effective. The use of the product as a spot treatment versus a broadcast spray also influences its longevity. It’s essential to monitor treated areas and reapply as needed to maintain desired control.
Targeted Areas
RM43 is primarily designed for use in areas where total vegetation control is desired, such as gravel driveways, walkways, parking lots, and fence lines. It is highly effective on hard surfaces like concrete and asphalt, where weeds often grow in cracks and crevices. It’s also suitable for industrial sites, around power plants, and other non-crop areas where vegetation needs to be eliminated. Users often apply it along borders, edges of buildings, and in other places where weeds are unwanted. However, care must be taken to avoid spraying RM43 in areas where desirable plants are present, as it will kill all vegetation it comes into contact with. It is crucial to apply RM43 in targeted areas to prevent runoff or overspray from damaging desirable grasses, flowers, or crops. It is not recommended for lawns or garden beds.
Restrictions and Limitations
RM43 has certain restrictions and limitations that users must be aware of. Firstly, its maximum application rate is 2.5 gallons per acre per year, or 7.4 fluid ounces per 1,000 square feet per year. Applying more than this can damage the soil and potentially cause runoff into unintended areas. It is also crucial to remember that RM43 is a non-selective herbicide, meaning it will kill any vegetation it comes into contact with, including desirable plants. Therefore, extreme caution should be taken to avoid overspray or drift. Additionally, it is not recommended to apply RM43 to areas where seeding or planting is planned in the near future, as the pre-emergent properties can inhibit seed germination. Also, application to areas near bodies of water should be avoided to prevent potential water contamination. It is also important not to cut or mow treated areas for at least two months after application to allow the herbicide to fully take effect and prevent regrowth.
RM43 Availability and Cost
RM43 is available at various retailers, including Tractor Supply and online stores like Amazon, though shipping restrictions may apply in some areas. It is generally more expensive than glyphosate-only herbicides due to the inclusion of a pre-emergent.
Where to Purchase
RM43 can be found at a variety of retail locations and online marketplaces. Major farm supply stores like Tractor Supply often carry RM43 in various sizes, catering to both small and large-scale needs. You might also find it at home improvement stores, though availability can vary by region. Online retailers, such as Amazon, are another avenue for purchasing RM43, however, it is important to be aware of potential shipping restrictions, particularly in states like California where regulations may limit herbicide deliveries. Additionally, checking the websites of agricultural product distributors can sometimes yield local suppliers. It’s advisable to compare prices across different vendors and consider factors such as shipping costs and local availability before making a purchase. Keep an eye out for promotions or membership discounts that may lower the overall expense of the product.
Price Comparison with Other Herbicides
RM43 typically costs more than standard glyphosate-only herbicides like Roundup, particularly when comparing equivalent volumes. This higher price is largely attributed to RM43’s dual-action formula that includes a pre-emergent component, providing both immediate weed kill and longer-term prevention. While Roundup might be more cost-effective for simple weed control, RM43’s pre-emergent capabilities offer a higher value proposition for areas where extended control is desired, such as patios, driveways, or gravel areas. Some users have mentioned RM43 being about twice the cost of Roundup for similar quantities, highlighting the premium associated with its combined action. Other options, such as mixing glyphosate with imazapyr, can achieve similar results but may not be as cost-effective or convenient as using a pre-mixed solution like RM43. It’s important to consider the total cost of control when making a decision, factoring in the need for repeat applications and the desired duration of weed prevention.
