Eraser Maxx Super Concentrate

Two herbicides in one jug. The glyphosate takes down what is standing there now, from bermudagrass and thistle to blackberry and kudzu. The imazapyr stays behind in the soil, and that is what keeps a gravel drive or a fence line clear for up to a year instead of green again by August.

Ground That Is Meant to Stay Bare

Spray it here

  • Gravel driveways, parking areas and paved surfaces
  • Sidewalks, patios and brick walks
  • Fence rows, hedgerows and fencing around paddocks, corrals and livestock pens
  • Farm yards, barn surrounds and uncultivated ground
  • Vacant lots, industrial sites, storage yards, lumberyards and petroleum tank farms
  • Roadsides, curbs, airports and dry ditchbanks
  • Under asphalt, applied before the surfacing goes down

Keep it away from

  • A lawn you want to keep. Nothing in this jug tells a desirable grass from a weed.
  • Vegetable gardens, flower beds and anything you plan to plant within a year
  • The root zone of a tree or shrub you value. Stay back twice the distance from the trunk to the drip line.
  • Slopes above desirable plants, where treated soil and runoff travel downhill
  • Powdery, dry or light sandy soil on a windy day. Let rain or irrigation settle the surface first.
  • Fish pools, ponds, lakes and streams
  • Food crops, feed crops and any ground being prepared for them

A fence does not stop a herbicide

Drift is the obvious risk along a boundary. Soil movement is the one people miss. Imazapyr keeps working in the ground it lands on, so a clean strip on your side of a fence can reach a hedge, an ornamental bed or a neighbor's young trees rooted on the other side.

Walk the line and look at both sides before the first pass. A bare rural fence, a livestock pen or a boundary with nothing planted against it is the situation this product was built for.

How Much Eraser Maxx Per Gallon

Bare ground

7.4 fl oz per 1,000 sq ft

Mix that 7.4 fluid ounces into anywhere from 1 to 10 gallons of water. The water volume follows your sprayer and how much liquid it takes you to cover the ground evenly. The 7.4 fluid ounces does not move.

Treat the area uniformly rather than heavily in patches. Spraying one strip twice does not make up for the strip you skipped, and the annual ceiling is 2.5 gallons of concentrate per acre, which is the same 7.4 fluid ounces per 1,000 square feet per year.

Spot treatment

6 fl oz per gallon of spray

Established weeds, brush and vines get sprayed at this stronger mix. Wet the foliage thoroughly and evenly, right up to the point where it is damp all over and no further.

The annual ceiling still applies. Spot spraying at a concentrated rate does not buy you extra product for the same ground in the same year.

A gallon of concentrate is not a gallon of spray

Start from square footage, never from tank size. Measure the area, take 7.4 fluid ounces for every 1,000 square feet of it, then add whatever water your equipment needs to spread that dose evenly.

A 2 gallon pump-up calibrated to cover 1,000 square feet holds the full dose. So does a tow-behind putting the identical 7.4 fluid ounces into 10 gallons. Extra water carries the same herbicide further without weakening it. One gallon of Eraser Maxx works out to roughly seventeen of those 1,000 square foot doses.

Backpack sprayers, pump-up sprayers, sprinkling cans and ATV or tractor-mounted rigs all apply it. Calibration matters more than capacity: mark out 1,000 square feet, walk it at the pace you actually spray, and measure how much water your equipment put down.

When to Spray

Conditions on the day

  • Sunny, with the temperature above 60°F
  • Wind under 10 mph
  • No temperature inversion, meaning the still, cool layer of air that settles near the ground at dawn and dusk and holds spray in place
  • Nozzle no more than 4 feet above the ground or the plant canopy
  • Coarse droplets or larger, which fall where you aim them instead of drifting

Getting the vegetation ready

  • Weeds actively growing. Early summer gives the strongest result on bare-ground work.
  • Anything over 6 inches tall gets cut or mowed, the debris raked off, then about two weeks to put out fresh growth
  • Brush and vines respond best from late summer into fall, after the fruit has formed
  • Brush that was already cut needs its leaves fully back before spraying is worth the effort
  • Nothing you treat gets mowed or cut for two months afterward

What “up to one year” actually means

Twelve bare months is the ceiling, not the schedule. Sites that take heavy rainfall move the soil-active portion through faster and often want a second pass at six to eight months. Heavy clay holds it longer, sometimes past the year.

Weed species, root depth and how evenly you covered the ground all shift the number. Treat the year as an upper bound and look the site over in late spring.

Give it a week before you judge the result. Nothing collapses on spray day, because both active ingredients have to travel inside the plant before anything shows on the outside.

Partial control is a real category

Phragmites, torpedograss, alligatorweed and leafy spurge appear with that qualifier attached, and so do several woody species. Finding a plant on a label list is not a promise that one pass removes it.

Growth stage, root reserves and how completely you wet the foliage decide the outcome. Stubborn perennials sometimes need a second treatment, taken out of the same annual allowance rather than added on top of it.

Residual activity is the whole difference. A glyphosate-only concentrate handles whatever is green on the day you spray and then leaves the soil open, which is exactly what you want before replanting a bed. Eraser Maxx adds imazapyr and takes that option off the table for a season.

RM43 sits on the same two numbers as Eraser Maxx, so the choice between those two comes down to container size, price and what your local store keeps in stock rather than to chemistry.

FormLiquid super concentrate, non-selective
Glyphosate43.68% isopropylamine salt, 3.2 lb per gallon acid equivalent
Imazapyr0.78%, 0.062 lb per gallon acid equivalent
Herbicide groupsWSSA Group 9 (glyphosate) and Group 2 (imazapyr)
EPA Registration No.53883-439

Two herbicide groups means two separate ways of stopping a plant. Glyphosate blocks an enzyme plants need in order to build proteins. Imazapyr blocks a different one, and it does that from the soil as well as from the leaf.

Handling It Safely

What to wear

A long-sleeved shirt, long pants, shoes and socks cover anyone mixing, loading or spraying. Wash your hands with soap and water before eating, drinking, chewing gum, using tobacco or using the toilet. If pesticide gets inside your clothing, that clothing comes off immediately, you wash, and you put on something clean. Heavily soaked absorbent clothing is not worth keeping.

If it reaches your eyes

Eraser Maxx carries the signal word CAUTION and can cause moderate eye irritation. Hold the eye open and rinse slowly and gently with water for 15 to 20 minutes. Take contact lenses out after the first five minutes, then keep rinsing. Call a poison control center or a doctor, and keep the container with you so the exact formulation can be identified.

People and pets

Keep everyone out of the area while you spray, and keep them out until the treatment has dried. Drying decides when it is safe to walk back through, which is a separate question from how quickly rain stops mattering.

Storage and empty containers

Store it in the container it came in, somewhere secure, and protect it from freezing. Never let it contact oxidizing agents, which can trigger a hazardous chemical reaction. Containers under 5 gallons cannot be refilled: triple rinse or the equivalent as soon as one is empty, then recycle it where recycling is available. Leftover concentrate, spray mix and rinsate never go down a drain, into a waterway or onto unapproved ground.

Works very well. Takes a few days to notice, but it eliminates most any vegation. Careful with overspray/ mist on plants you want to keep.

About Martin's Eraser Maxx

Eraser Maxx sits at the long-residual end of the Martin's herbicide range. Most of what carries that name is built the same way: a concentrate aimed at one clearly defined job, sold to people who would rather measure and mix than pay for a ready-to-use bottle that is mostly water.

The job here is not killing a weed. Plenty of products kill a weed. This one takes vegetation off non-crop ground and then holds that ground, which is a different problem and needs different chemistry to solve.

A gravel drive that greens over every spring is nothing like a dandelion in a lawn. Neither is a fence row that has to stay clear, a vacant lot perimeter, or an industrial strip where growth gets in the way of maintenance. Those sites are what justifies pairing a high-concentration systemic herbicide with residual soil activity.

That same persistence is the reason to be careful with it. Where nothing is supposed to grow, it is the whole point of the product. Anywhere else it is the problem.

Frequently Asked Questions

Eraser Maxx Super Concentrate Herbicide is a non-selective herbicide for controlling unwanted grass, broadleaf weeds, brush and vines in non-crop areas. It contains 43.68% glyphosate and 0.78% imazapyr. The formula kills existing susceptible vegetation and provides residual activity in treated soil, allowing total vegetation control for up to one year under suitable conditions.

The container reads ERASER MAXX SUPER CONCENTRATE, with two Xs. Eraser Max is how a great many people type it, and both spellings point at the same Martin’s product. To be certain which formulation is in your cart, look for Super Concentrate on the front panel and EPA Reg. No. 53883-439 on the label.

Eraser Maxx can provide total vegetation control for up to one year from a single properly applied treatment. Actual duration depends on rainfall, soil conditions, weed pressure and application coverage. Areas with heavy rainfall may require another treatment after approximately six to eight months. Residual activity can persist longer in some heavy clay soils.

Eraser Maxx controls a broad range of grasses, broadleaf weeds, vines and woody plants. Labeled targets include bermudagrass, dallisgrass, johnsongrass, quackgrass, tall fescue, nutsedge, dandelion, ragweed, Canada thistle, field bindweed, blackberry, honeysuckle, kudzu, poison ivy and poison oak. Some difficult species are listed for partial rather than complete control, so results can vary by plant and growth stage.

No. Eraser Maxx is non-selective and can kill desirable lawn grasses along with the weeds growing among them. It is intended for areas where vegetation is not wanted, such as gravel surfaces, fence lines and similar non-crop sites. A selective lawn herbicide is a better choice when the grass itself needs to survive.

No. This is a non-selective herbicide, which means it kills whatever green tissue the spray lands on, bermudagrass and fescue included. The full directions rule out treating established turf you intend to keep, and they rule out seeding a new lawn for up to a year afterward. Reach for a selective turf herbicide when the grass has to come through the treatment alive.

Eraser Maxx is labeled for total vegetation control in many non-crop areas, including driveways, sidewalks, patios, gravel paths, fence rows, vacant lots, farm premises, parking areas, industrial sites and certain roadsides. Always check the current product label before application, because permitted sites and restrictions determine where the herbicide may legally be used.

The correct amount depends on the type of treatment. For spot treatment of established weeds, brush and vines, use 6 fluid ounces of Eraser Maxx per gallon of finished spray. Bare-ground treatment is calculated by area rather than by gallon of water. Apply 7.4 fluid ounces of concentrate per 1,000 square feet using enough water, from 1 to 10 gallons, to cover that area uniformly.

A 32-fluid-ounce quart contains enough concentrate for approximately 4,300 square feet of bare-ground treatment when applied at the labeled rate of 7.4 fluid ounces per 1,000 square feet. Coverage refers to the amount of concentrate required. The quantity of water used to distribute it can vary according to sprayer calibration and application conditions.

Eraser Maxx is rainfast within one hour after application. Rain falling after that hour does not wash the treatment off the foliage. One hour describes resistance to rainfall, not how fast the plants die.

Eraser Maxx contains systemic herbicides that move within susceptible plants rather than only burning exposed leaves. Glyphosate is absorbed primarily through foliage and interferes with a plant process required for growth. Imazapyr also has systemic activity and contributes residual soil control. This makes Eraser Maxx better suited to established perennial vegetation than contact-only products that damage only the tissue directly sprayed.

Eraser Maxx should not be applied over the root systems of desirable trees or shrubs. Keep the treatment away from valuable woody plants, and measure the spacing from the tree’s drip line rather than from its trunk. Roots often extend well beyond the trunk and can grow beneath gravel, driveways and apparently bare areas. Because imazapyr remains active in soil, avoiding direct spray contact with the trunk alone is not enough to protect a nearby tree.

Eraser Maxx should not be used where desirable plants will be established soon after treatment. Its residual soil activity can prevent or damage future plant growth for up to one year, and potentially longer under some soil conditions. Do not use it as a preparation treatment for a lawn, vegetable garden, flower bed or other area that needs to be replanted shortly afterward.

A conventional glyphosate-only herbicide primarily controls vegetation that is already growing when it is sprayed. Eraser Maxx combines glyphosate with imazapyr. The imazapyr component adds residual soil activity, allowing the treatment to suppress vegetation long after the initial application. That makes Eraser Maxx more appropriate for long-term bare-ground control and less appropriate for areas that will soon be replanted.

Yes. RM43 and Eraser Maxx carry the same headline active ingredient concentrations, 43.68% glyphosate isopropylamine salt with 0.78% imazapyr, and Control Solutions treats RM43 as the direct comparison for Eraser Maxx. Follow the label on the container you actually buy. Similar active ingredients do not automatically make every application rate, restriction or state registration interchangeable.

Eraser Maxx is part of the Martin’s product line from Control Solutions Inc., a U.S.-based specialty chemical company headquartered in Pasadena, Texas. Control Solutions develops products for consumer lawn and garden use, professional pest management, turf and ornamental applications, and animal health markets. The company operates brands including Martin’s and is part of the ADAMA Group.

Eraser Maxx is available in three concentrate sizes: 1 quart, 1 gallon and 2.5 gallons. The quart is suited to smaller residential or property-maintenance jobs. One gallon provides approximately 17,300 square feet of bare-ground coverage at the labeled rate, and the 2.5-gallon container provides approximately 43,200 square feet. Container size does not equal finished spray volume. Eraser Maxx is diluted with water before use, so each package can produce substantially more spray solution than the amount of concentrate in the container.

Measure the Area, Then Mix

Work out the square footage first. The dose follows from that number, and so does the container size worth buying.
