Why Compare?
The short answer is that both products are effective. They will both kill weeds before they have a chance to grow. However, you should be aware of some key differences between the two products.

Glyphosate is a broad-spectrum herbicide, which means it will kill any plant with which it comes in contact. This includes both weeds and desirable plants. Triclopyr is a selective herbicide, which means that it will only kill certain plants. This makes it ideal for use around desirable plants that you don’t want to kill.

Active Ingredient
Glyphosate is the active ingredient in Roundup, and it works by interfering with a plant’s ability to produce amino acids. This ultimately kills the plant. Triclopyr is the active ingredient in Garlon, and it works by causing cell death in plants.

What it Kills?
Garlon 4 Ultra Herbicide uses the active ingredient triclopyr to control 80 different plants! This makes Garlon 4 Ultra one of the most versatile herbicides on the market. This herbicide can kill Cherry, loblolly pine, mesquite, red oak, sweetgum, alder, ash, birch, blackberry, ceanothus, chinquapin, clover, dandelion, dogwood, elm kudzu, maple oak, poison ivy ragweed wild violet and other brush and broadleaf weeds.

Roundup, however, is designed to kill weeds with which Roundup’s glyphosate active ingredient comes into contact. This includes crabgrass, dandelions, and other broadleaf weeds. Roundup will also kill grasses, including Bermuda, St. Augustine, centipede, zoysia grasses, and many more.

For Use In
Triclopyr is the active ingredient in Garlon, and it can be used in pastures, rangelands, rights-of-way, and other non-crop areas to control brush and broadleaf weeds. Glyphosate is the active ingredient in Roundup, and it can be used in agricultural areas, commercial & residential lawns, and gardens to kill weeds.

Garlon may be the better choice if you need to kill brush and broadleaf weeds in pasture, rangeland, or right-of-way areas. Roundup may be the better choice if you need to kill weeds in agricultural areas, commercial & residential lawns, or gardens.

How to Use?
Garlon should be applied with a hand-held or backpack sprayer. Roundup can be applied with a hand-held, backpack or pump sprayer. When using either product, be sure to read and follow the label directions.

For Garlon, you will want to spray the product on the lower 12 to 15 inches of bark around the stem. Make sure to apply it until the bark is wet. Do not apply when the bark is wet from rain or heavy dew. If the product turns white when applied, that is an indicator that the bark is too wet.

When using Roundup, you need to be careful. You must use a mixed solution to spray the weeds and grasses you want to kill. If you are spraying weeds near desirable plants, shield them from the Roundup with a piece of cardboard or plastic. If desirable plants are accidentally sprayed, rinse them off with water right away.

Our Observation
Both products are effective at killing weeds. However, there are some key differences that you should be aware of before choosing one over the other. Garlon is more selective in what it kills, and Roundup will kill any plant it comes into contact with. Garlon is also less likely to harm desirable plants if used as directed.

If you need to kill brush and broadleaf weeds, Garlon is the better choice. If you need to kill grasses or broadleaf weeds near desirable plants, Roundup is the better choice. Be sure to read and follow all label directions before using either product.
