RM43 Mixing Ratio Guide

Whether using RM43 to treat individual plants or specified regions, consistent herbicide application is critical for successful weed control. Changing the application rate or dilution ratios even minimally may result in a poor outcome or needless waste of product—both of which are a loss of time, money, and effort.

The RM43 Weed Killer promises to kill weeds fast, but does it really perform efficiently? The RM43 herbicide has a glyphosate complement of 43%. As a result, it may effectively kill undesired plants at the root level. Many additional labels work by physically damaging the vegetative component of the weed. By eliminating the organisms at the root, you may get rid of them for up to a year.

RM43 43-Percent Glyphosate Plus Weed Preventer Total Vegetation ControlRM43 43-Percent Glyphosate Plus Weed Preventer is a powerful herbicide designed to kill and prevent the growth of weeds for up to a year. With the ability to treat over 17,000 square feet, it is perfect for use along fence rows, driveways, sidewalks, and around farm buildings and barns.

RM43 is sold in 3 different sizes. Here’s a helpful chart that shows how much each bottle covers:

  • 1 quart can cover up to 4,324 sq. ft.;
  • 1 gallon can cover up to 17,300 sq. ft.;
  • 2.5 gallons can cover up to 43,243 sq. ft.;

The manufacturer’s recommendation on the RM43 mixing ratio

7.4 ounces of RM43 mixed with 1–10 gallons of water is suggested. This will span 1,000 square feet, about the size of ten parking spots or a four-car garage. Read the label for full information. Combine 6 ounces of RM43 weed killer with 1 gallon of water for spot weed control.

How to mix RM43 properly?

The most essential aspect is coverage, or how much product is applied over a particular surface area. To achieve the best coverage with RM43, you must have the proper dilution and amount of spray, as well as move at the proper speed:

Figure out the proper dilution ratio

The appropriate ratio will be determined by your weed control objectives. Combine 7.4 fluid ounces of product with whatever much water is required to cover 1,000 sq. ft. using your gear for complete vegetation control when a bare ground outcome is desired. Depending on the kind of sprayer and the pace of the sprayer, this may range from 1 to 10 gallons of water. Combine 6 oz of product per 1 gallon of spray for spot treatment.

Use the right rate and volume of spray

Of course, the amount of chemical mixed per gallon is just one aspect of the application process. The most essential aspect is coverage, or how much product is applied over a particular surface area. Understanding the dilution ratio and coverage levels is critical for avoiding over- and under-application and optimizing your time, effort, and funds. Use some water to have the solution through the pebbles to the ground on gravel driveways.

According to FlowersProfy, RM43 is best sprayed with a coarse droplet size or, if applying a spinning atomizer nozzle, a volume mean diameter of 385 micros or more, while keeping the sprayer nozzle height below 4 ft. above the ground or plant canopy. Whether you’re spot treating or looking for bare ground control, the objective here is complete, even coverage over all current leaf structures and enough substance reaching the ground to provide 12-month control.

Go slowly

Once per year, RM43 has the limit of the application rate of 2.5 gallons per acre, regardless of dilution ratio. Remember this while calculating your rate of dispersion. The variation between 1mph and 4mph may be attributed to speed. Using a dye can also help you evaluate whether you’re getting the right droplet size and density. When calculating the proper sprayer speed, consider the chemical dilution and spray volume.


How to mix RM43 Total Vegetation Control properly?

Herbicides that destroy all the unwanted vegetation also prohibit them from growing in a particular region for up to a year. Handheld sprayers, such as backpack/pump-up/ATV/tractor-mounted sprayers or sprinkling cans should be used. Apply a spray solution with 6 oz. of product diluted in 1 gallon of water. To moisten the leaves of woody plants, thoroughly and evenly spray the solution.

Can RM43 destroy trees?

It can. But be cautious when spraying near young and established trees. If you wish to kill a tree, RM43 can destroy and prevent it from growing back; but, based on the size of the tree, there may be simpler, faster, and more cost-effective methods.

How much RM43 is in one gallon of water?

The suggested concentration for complete vegetation control, which means weed-free down to the bare ground, is 7.4 fl. oz of RM43 per gallon of water – no more than ten gallons.

Do you need to mow the lawn before spreading RM43?

Mow down weeds taller than 6 inches to make RM43 more effective. After mowing, remove any waste and wait 2 weeks for fresh weed growth and complete leaf formation on woody vines or bushes.

How quickly does RM43 require work?

In 2 or 3 days, you will begin to notice the effects. Total plant removal will take longer and will be determined by the kind of weeds present as well as weather conditions, especially temperature. In warmer weather, RM43 has been shown to function quicker.

One of the benefits of utilizing RM43 is how fast it operates. Because plant protein synthesis is hindered, the formula quickly travels throughout the whole plant until eaten, and the target weed’s development is reduced soon after contact. Plants absorb RM43 via both their roots and their leaves. It also rapidly prevents vulnerable weeds from developing.

And, although visible indications may take some time to appear, weed growth stops within 24 hours after a single treatment. The sensitive weeds will become yellow or brown in 2 to 3 weeks. In warm, wet settings, rather than cold, dry ones, the herbicidal impact would be enhanced.

According to several user reports, the following are the RM43 weed killer results:

  • After 36 hours – no visible results;
  • After 7 days – you will start to notice the discoloration of the affected weeds;
  • After 2 weeks  – the complete destruction of weeds;
Tips for users: rain or irrigation within 2 hours of application may rinse this product off the leaves, requiring a repeat application for efficient weed control.

What equipment do you need for the RM43 application?

A handheld sprayer or an ATV/tractor-mounted spreader may be used with this product. Read the label for instructions on application rate and machine cleaning.
