The Martin’s Eraser & Grass Concentrate Weed Killers

Erase weeds and grass with the Martin’s Eraser & Grass Concentrate Weed Killers. It works because of the active ingredient 41 percent glyphosate serving as a non-selective killer. Do not spray this product on your lawn unless you are hoping to start from scratch!

Say goodbye to weeds and grass in your walkways, driveways, flower beds, fence lines, and so many other places. Simply buy a sprayer, add some concentrate and water, then spray the weeds completely. You do need to use this spray on pre-existing weeds as it kills living plants and does not prevent those green invaders from spouting up.

Next, make sure the weather is warm, sunny, and dry, then spray away. It dries quickly and can work just an hour before rain. Keep kids and pets away from the law until it’s completely dry. Also, any plants that get hit by the spray accidentally can be rinsed with water while the spray is still wet.

Last of all, you can replant flowers in as little as one day and lawns in seven. A single quart will cover large spaces and least a long time depending on the size of your lawn as that quart translates to 21 gallons of spray. You will want to wear safety equipment with all herbicides for safety.

5. Trimec Lawn Weed Killer

Trimec Lawn Weed Killer review
The Trimec Lawn Weed Killer

Use Trimec Lawn Weed Killer if you want to kill weeds on your grass without killing your grass. The selective killer can reduce over 250 weeds. You can use the spray for spot treating or for massive tracts of land to get your yard beautiful again and the envy of all your neighbor’s thanks to pure grass without intruders.

The three-way herbicide blend effectively kills dandelion, white clover, chickweed, thistle, and more. However, the spray does not work on carpet grass, floratam grass, dichondra grass, or clovers. Also, its rain safe six to eight hours after application. People and animals can re-enter the yard after the mixture has dried completely, which depends on the weather conditions.

To guarantee you have enough mixture to cover your entire lawn, measure the length and width to get your total square footage. One bottle covers up 8,000 square feet of northern grasses and closer to 16,000 square feet of southern grass. For spot treatment, mix one ounce with a gallon of water in a sprayer and treat the individual areas.

Read the directions for how to mix for the different types of grasses you may be treating. Each grass is different and needs a different solution grade for the most effective job. Wait two to three days to mow the lawn after applying this effective weed killer. Finally, you can only apply once a month to maintain the health of your grass. The only complaint is the price as many customers found it on the pricy side.

  • Kills Hard-To-Control Lawn Weeds
  • For Use On Cool-Season Grasses
  • Available In one gallon

6. Spectracide Weed & Grass Killer Concentrate

Spectracide Weed & Grass Killer Concentrate review
The Spectracide Weed & Grass Killer Concentrate

With Spectracide Weed & Grass Killer Concentrate, you get an effective killer ready to destroy weeds and grass with a three-step approach. The first ingredient in the liquid is taken up by the roots and shoots of leafy plants to kill the internal cells. Ingredient number two works on leaves of grassy weeds to inhibit their ability to grow. The third ingredient works on all plant surfaces by absorbing on contact.

Unlike other non-selective weed and grass killers, Spectracide doesn’t use glyphosate and instead uses diquat dibromide, fluazifop-p-butyl, dicamba, and dimethylamine salt as the active ingredients. The vast majority of the ingredients are inactive and help to retain the active ingredients shelf life. However, the product still interferes with photosynthesis to prevent weeds and grass from living in the wrong spots.

What’s fantastic about the product is it’s rainproof in just fifteen minutes, and you get visible results in as little as three hours. Moreover, the concentrate works by killing the root so the weed cannot sprout back up. Also, you can plant new flowers, trees, and shrubs to the treated area the next day.

Buy a sprayer to mix and apply the spray to those tough areas where you need weeds and grass gone. As always, apply in warm, dry conditions with low or no wind. Completely cover the target foliage to see results in one application. Finally, the product comes in multiple sizes to cover both small and large areas.

Spectracide Weed & Grass Killer Concentrate, 64 Fl Oz
  • Kills weeds and grasses: Use on driveways and walkways, and around fences, trees, flower beds, shrubs and other areas in your yard
  • Kills the root: Visible results as fast as 3 hours – replant new flowers, trees and shrubs the same weekend
  • Rain-fast: Rainfall or watering 15 minutes after application will not wash away effectiveness
  • Concentrate: Mix and apply with a tank sprayer – Spray to completely cover the leaves of the target vegetation
  • Money-back: Results or your money back – see product label for details

Buying Guide for Weed Killer

Before you pick a weed killer to get rid of unwanted guests in your lawn, take a look at some important information to help you make the best decision.

Yard Coverage

When you pick a concentrated herbicide, you need to mix it with water first. This means even a small bottle can cover the vast majority of your yard. The larger your yard, the more weed killer you will need. Make sure to read the label before spraying to find the right dilution for the weed killer.

Types of Weed Killer

Weed killers come in a variety of types to kill different plants. Many, like the options on this list, will kill a variety of weeds. Moreover, some weed killers kill both grass and weeds, which you will want if you are trying to kill any plan in pavers, flower beds, or other areas that aren’t your lawn. Instead, you may want a grass safe weed killer instead of the lawn.

Moreover, weed killers can be selective or non-selective. The latter will kill any plant you spray it on while a selective only works on specific plants without killing everything. You can also pick a systemic weed killer to reduce even the roots to dust, while a topical will only kill the top of the plan. Finally, some weed killers are persistent and will stay active to kill even future weed invasions while non-persistent works one time.

Different Types of Weeds

Every location contains different weeds, and not all weed killers work for every kind of lawn. Make sure to check the local weeds and what chemicals kill those specific intruders. Also, check local weather and season as some weed killers only work in dry climates while others will work during rain. Also, if you have a specific plant you want to kill, and it’s resistant to standard broad coverage weed killer, then you may need a specific killer for that weed.

Questions About Weed Killers

How do I apply weed killer?

First things first, make sure to see if your weed killer needs to be diluted. Make sure it’s not going to rain soon, even if some of the weed killers will work right before the storm. From there, follow a systematic pattern to cover your entire lawn without repeating. Apply an even layer across all of the weeds and then wait for the weeds to meet an untimely death.

Will weed killers harm my dog?

Yes, weed killers are herbicides that can kill plants and potentially harm both animals and humans. Check the bottle of your weed killer for instructions on how long before your pets or children can go back out into the yard to prevent issues.

While herbicides’ results may not be immediate, they can cause long-term problems and even lead to cancer. If possible, take your dog for a walk to relieve themselves instead of sending them to the backyard after spraying. Wait a full day if you can before sending your dog back out into a yard filled with weed killer.

Is it possible to be allergic to weed killer?

Yes, it is possible to be allergic to weed killer. Some people experience severe symptoms such as massive swelling, breathing issues, nausea, weakness, dizziness, and more. Even if you don’t have an allergy, it might be smart to wear a mask and eye cover to prevent unnecessary exposure and prevent a possible reaction. Also, you can use organic or natural options to avoid allergies if you know you have a sensitivity as they are safer and vinegar-based.
