Monterey Weed Whacker

Weed Whacker is a three-way selective post-emergent herbicide for use on residential turf and non-crop areas to control over 140 broad-leaf weeds like spurge, oxalis, dandelions, and others. The concentrated formula is an economical way to kill unwanted broad-leaf weeds and can be used in cool and warm season grasses.

Determine area to be sprayed. Apply at a rate of 32 fluid ounces (1 quart) per 10,000 square feet for Cool Season grasses or 20,000 square feet for Warm Season grasses.


Cool Season Grasses - such as Bluegrass, Fescue, and Rye: To kill Dandelion, Wild onion, Pennywort, Plantain, Healall and similar weeds: use 8 to 13 fluid ounces in 6 gallons of water and apply with pump or hose-end sprayer or sprinkling can to 2,500 square feet of lawn. For smaller areas - use 3 teaspoons in 2 quarts of water applied to 100 square feet.

To kill undesirable weeds such as Thistle, Bindweed, Dock and Ragweed, use 8 fluid ounces in 6 gallons of water (or 3 teaspoon in 2 quarts of water), and apply directly to plants, wetting them thoroughly.

To kill undesirable plants such as Poison ivy and Poison oak, use 2 fluid ounces in 1 quart of water and drench plants when they are fully leaved. Repeat in about 4 weeks if necessary. Certain hard-to-control weeds such as Poison ivy, Poison oak and English daisy may require a Fall application.

Warm Season Grasses - St. Augustine, Bahia, common Bermuda, Centipede, Zoysia, also for Bent: Use a one-half rate which is 4 to 6 1/2 ounces in 6 gallons of water to treat 2,500 square feet (3 teaspoons in 4 quarts of water applied to 200 square feet). Make two applications 30 days apart. Do not spray grasses if stressed from heat, drought, etc. Slight turf yellowing should disappear after about 1 week.

Note: Some hybrid Bermuda grasses may be sensitive to Weed Whacker.

For Spot Treatment: Put 3 teaspoons of Weed Whacker into an empty quart container with trigger sprayer. Then add 30 fluid ounces of tap water. Trigger Sprayer - Adjust spray nozzle to give coarse spray. Aim at center of weed and spray to wet. One application should be sufficient. Effects begin to show after a few days and weeds gradually die. A repeat application may be required in 4 weeks for hard-to-control weeds.

  • 4 of 5 stars  Weed Whacker Works
    By Larry in Central Wisconsin, WI on 09/17/2016

    Some stubborn weeds developed in my lawn that didn't seem to be affected by the off the shelf products. After doing some research it seemed that Weed Whacker would do the job and, after one application, more than half of the weeds are gone. I plan a second application. I've ordered from Do My Own Pest Control before. It is a great company to work with. They ship everything quickly and correctly. No problems!

QDo you water Weed Whacker before application?

AIf the lawn needs watering, water thoroughly before application of Weed Whacker. Otherwise, apply at 4 - 13 oz. per 6 gallons of water per 2,500 sq. ft. Do not water 48 hours after application per the product label instructions.

QCan Monterey Weed Whacker be used in flower beds or will it kill the flowers?


Monterey Weed Whacker cannot be used in flower beds. We do carry Fertilome Over the Top II Weed Killer that can be applied around flowers, bedding plants, ornamental groundcovers, trees, shrubs and listed edibles on the label. Please check the product label to see if this will work for the weeds you need to control.

Can Weed Whacker be used on Floratam, Palmetto, St. Augustine in temps above 85 degrees?

AAccording to the Weed Whacker product label, you can use this product up to 90 degrees. It states that is is safe for St Augustine grass however it does not state if it is safe for all blends. We know Floratam is the most sensitive species of grass and we dont want you to potentially harm it. Please contact the manufacturer Monterey Lawn & Garden to make sure it is safe for your turf species: 1-559-499-2100. Please let us know if you have any other questions.
